Windows 8 C#/XAML SuspensionManager failed - c#

I'm writing simple imageviewer for one imageboard. I'm using these 2 classes for navigation(navigation parameter for Frame.Navigate() method) in my app:
public class KonaParameter
{
public int page { get; set; }
public string tags { get; set; }
public KonaParameter()
{
page = 1;
}
}
public class Post
{
public int id { get; set; }
public string tags { get; set; }
public int created_at { get; set; }
public int creator_id { get; set; }
public string author { get; set; }
public int change { get; set; }
public string source { get; set; }
public int score { get; set; }
public string md5 { get; set; }
public int file_size { get; set; }
public string file_url { get; set; }
public bool is_shown_in_index { get; set; }
public string preview_url { get; set; }
public int preview_width { get; set; }
public int preview_height { get; set; }
public int actual_preview_width { get; set; }
public int actual_preview_height { get; set; }
public string sample_url { get; set; }
public int sample_width { get; set; }
public int sample_height { get; set; }
public int sample_file_size { get; set; }
public string jpeg_url { get; set; }
public int jpeg_width { get; set; }
public int jpeg_height { get; set; }
public int jpeg_file_size { get; set; }
public string rating { get; set; }
public bool has_children { get; set; }
public object parent_id { get; set; }
public string status { get; set; }
public int width { get; set; }
public int height { get; set; }
public bool is_held { get; set; }
public string frames_pending_string { get; set; }
public List<object> frames_pending { get; set; }
public string frames_string { get; set; }
public List<object> frames { get; set; }
public object flag_detail { get; set; }
}
The problem I faced is that suspending doesn't work. SuspensionManager throws "SuspensionManager failed" exception after await SuspensionManager.SaveAsync(); call(I googled that it's because of using complex types).
I tried to use string as a navigation parameter. It works, but I need more than 1 string for my parameter(List<string> doesn't work, I tried to use it).
How to suspend my app correctly?

The problem is that SuspensionManager uses Frame.GetNavigationState() to get the history of the Frame. It then tries to serialise the navigation history to a string, unfortunately it has no way to know how to serialise custom complex types as parameters like Post or KonaParameter and fails with an exception.
If you want to use SuspensionManager then you'll need to restrict yourself to simple types like int or string as parameters.
If you do need complex types then it's best to store them in some background service / repository with an identifier. You can then pass the identifier as the parameter.

The recommended approach is to serialize your "state" object, so it can be saved/restored as a string. You can use Json.NET to do this:
//save state
Post post = //...;
string state = JsonConvert.Serialize(post)
//restore state
Post post = JsonConvert.Deserialize<Post>(state);
If you want to use two objects (a Post and a KonaParameter), I'd consider creating an "aggregate" class that encapsulates both, and serializing/deserializing that instead:
public class State
{
public Post post {get; set;}
public KonaParameter param {get; set;}
}

i'm trying to run through some JSON seralisation into some objects. pretty straight forward stuff.
for some reason i have the first part working as expected, it seralises perfectly.
the moment i wrap this JSON in an additional element the Deseralize Object passes, but the object is empty... i cannot spot the issue and i cannot seem to debug what's going on here.
string UIElement = "{\"Name\":\"X1144\",\"Order\":1,\"Tvalue\":\"int\",\"BindValue\":null,\"Default\":null,\"Disabled\":false,\"Mandatory\":true,\"MandatoryMessage\":\"this is a mandatory field\",\"Label\":\"<B> THIS is a HTML</b> label\",\"ToolTip\":\"just a tooltip\",\"PolicyProcess\":[{\"URL\":\"https://google.com\"}],\"Type\":\"RadzenColorPicker\",\"TypeOptions\":[{\"Name\":\"showHSV\",\"Value\":\"True\"},{\"Name\":\"showRGBA\",\"Value\":\"True\"},{\"Name\":\"ShowColors\",\"Value\":\"True\"},{\"Name\":\"showButton\",\"Value\":\"True\"}],\"ItemsType\":null,\"Items\":[],\"Scorable\":false,\"Score\":0,\"Visibility\":true,\"VisibilitySettings\":{\"Condition\":\"OR\",\"Rules\":[{\"Id\":\"X1234\",\"Value\":\"Yes\"},{\"Id\":\"X1222\",\"Value\":\"Yes\"}]},\"KMRs\":false,\"KMRsSettings\":[],\"Docs\":false,\"DocsSettings\":[],\"AutoFill\":true,\"AutoFillSettings\":{\"Value\":\"#999999\",\"Condition\":\"AND\",\"Rules\":[{\"Id\":\"X1234\",\"Value\":\"No\"},{\"Id\":\"X1234\",\"Value\":\"No\"}]}}";
RadzenUIElement element = JsonConvert.DeserializeObject<RadzenUIElement>(UIElement);
Console.WriteLine("UIElement " + element.Name);
foreach (var item in element.VisibilitySettings.Rules)
{
Console.WriteLine( item.Value.ToString());
}
string RadzenPanel = "{\"RadzenPanel\":{\"Id\":\"asfdgsertw34t43t34\",\"RadzenUiElement\":{\"Name\":\"X1144\",\"Order\":1,\"Tvalue\":\"int\",\"BindValue\":null,\"Default\":null,\"Disabled\":false,\"Mandatory\":true,\"MandatoryMessage\":\"this is a mandatory field\",\"Label\":\"<B> THIS is a HTML</b> label\",\"ToolTip\":\"just a tooltip\",\"PolicyProcess\":[{\"URL\":\"https://google.com\"}],\"Type\":\"RadzenColorPicker\",\"TypeOptions\":[{\"Name\":\"showHSV\",\"Value\":\"True\"},{\"Name\":\"showRGBA\",\"Value\":\"True\"},{\"Name\":\"ShowColors\",\"Value\":\"True\"},{\"Name\":\"showButton\",\"Value\":\"True\"}],\"ItemsType\":null,\"Items\":[],\"Scorable\":false,\"Score\":0,\"Visibility\":true,\"VisibilitySettings\":{\"Condition\":\"OR\",\"Rules\":[{\"Id\":\"X1234\",\"Value\":\"Yes\"},{\"Id\":\"X1222\",\"Value\":\"Yes\"}]},\"KMRs\":false,\"KMRsSettings\":[],\"Docs\":false,\"DocsSettings\":[],\"AutoFill\":true,\"AutoFillSettings\":{\"Value\":\"#999999\",\"Condition\":\"AND\",\"Rules\":[{\"Id\":\"X1234\",\"Value\":\"No\"},{\"Id\":\"X1234\",\"Value\":\"No\"}]}}}}";
RadzenPanel panels = JsonConvert.DeserializeObject<RadzenPanel>(RadzenPanel);
Console.WriteLine("elements in panels " + panels.Id);
the output from this code is below;
UIElement X1144
Yes
Yes
elements in panels
as i progress i'm looking to enhance the RadzenPanel to hold an array of the UIElements, but right now i cannot get it to parse a single item..
the object structure looks like this;
public class RadzenPanel
{
public string Id { get; set; }
public RadzenUIElement RadzenUiElement { get; set; }
}
public class RadzenUIElement
{
public string Name { get; set; }
public int Order { get; set; }
public string Tvalue { get; set; }
public string BindValue { get; set; }
public string Default { get; set; }
public bool Disabled { get; set; }
public bool Mandatory { get; set; }
public string MandatoryMessage { get; set; }
public string Label { get; set; }
public string ToolTip { get; set; }
public PolicyProcessLink[] PolicyProcess{ get; set; }
public string Type { get; set; }
public TypeOptions[] TypeOptions { get; set; }
public string ItemsType { get; set; }
public Items[] Items { get; set; }
public bool Scorable { get; set; }
public double ContributionScore { get; set; }
public bool Visibility { get; set; }
public VisibilitySettings VisibilitySettings { get; set; }
public bool KMRs { get; set; }
public KMRsSettings[] KMRsSettings { get; set; }
public bool Docs { get; set; }
public DocsSettings[] DocsSettings{ get; set; }
public bool AutoFill { get; set; }
public AutoFillSettings AutoFillSettings { get; set; }
}
public class PolicyProcessLink
{
public string URL { get; set; }
}
public class TypeConstants
{
public const string RadzenCheckbox = "RadzenCheckbox";
public const string RadzenCheckboxList = "RadzenCheckboxList";
public const string RadzenColorPicker = "RadzenColorPicker";
public const string RadzenDatePicker = "RadzenDatePicker";
public const string RadzenDropDown = "RadzenDropDown";
}
public class TypeOptions
{
public string Name { get; set; }
public string Value { get; set; }
}
public class Items
{
public string Name { get; set; }
public string Value { get; set; }
public string BGColor { get; set; }
public string TColor { get; set; }
public bool IsScore { get; set; }
public double Score { get; set; }
public bool IsNa { get; set; }
public string KMRIndicator{ get; set; }
public string DocsIncicator { get; set; }
}
public class VisibilitySettings
{
public bool Value { get; set; }
public string Condition { get; set; }
public Rules[] Rules { get; set; }
}
public class Rules
{
public string Id { get; set; }
public string Value { get; set; }
}
public class KMRsSettings
{
public Guid Id { get; set; }
public double Weighting { get; set; }
}
public class DocsSettings
{
public Guid Id { get; set; }
public double Weighting { get; set; }
}
public class AutoFillSettings
{
public string Value { get; set; }
public string Condition { get; set; }
public Rules[] Rules { get; set; }
}

not sure what the exact problem was, but i solved it by working through the c# model and progressively built the JSON to suit.
the full debug process started with an approach that debugged the core element. RadzenUiElement (bottom up) followed by building out the wrapper for the whole lot top down.

I've been searching around for a long while for this, I haven't found any solutions to my issue which is:
I've been trying get a json data individually from a whole source seen here:
{"TargetId":0,"ProductType":null,"AssetId":1239281845,"ProductId":0,"Name":"❤️🍀𝐒𝐀𝐋𝐄❗️🍀❤️ Red&Black Flannel + Backpack","Description":"Shirt Image","AssetTypeId":1,"Creator":{"Id":124026176,"Name":"TheDestroyerPeter","CreatorType":"User","CreatorTargetId":124026176},"IconImageAssetId":0,"Created":"2017-12-12T19:48:24.693Z","Updated":"2017-12-12T19:48:24.693Z","PriceInRobux":null,"PriceInTickets":null,"Sales":0,"IsNew":false,"IsForSale":false,"IsPublicDomain":false,"IsLimited":false,"IsLimitedUnique":false,"Remaining":null,"MinimumMembershipLevel":0,"ContentRatingTypeId":0}
now what I've been trying to do with it is get the Product Name using C# and the product name is "❤️🍀𝐒𝐀𝐋𝐄❗️🍀❤️ Red&Black Flannel + Backpack", my issue is that I haven't found a way to extract the data, and when I have I haven't been able to get the right data, because instead if gives me "TheDestroyerPeter"
I've written up code, and deleted it, it was really sloppy and it would take awhile to rewrite, I appreciate any solutions
-whoever I am

You can use JavaScriptSerializer class, which is part of the System.Web.Script namespace.
For example :
var jsonString = #"{""name"":""John Doe"",""age"":20}";
var JSONObj = new JavaScriptSerializer().Deserialize<Dictionary<string, string>>(jsonString );
and then JSONObj["name"]; gives you "John Doe"
in this case you can use it :
public class Creator
{
public int Id { get; set; }
public string Name { get; set; }
public string CreatorType { get; set; }
public int CreatorTargetId { get; set; }
}
public class RootObject
{
public int TargetId { get; set; }
public object ProductType { get; set; }
public int AssetId { get; set; }
public int ProductId { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public int AssetTypeId { get; set; }
public Creator Creator { get; set; }
public int IconImageAssetId { get; set; }
public DateTime Created { get; set; }
public DateTime Updated { get; set; }
public object PriceInRobux { get; set; }
public object PriceInTickets { get; set; }
public int Sales { get; set; }
public bool IsNew { get; set; }
public bool IsForSale { get; set; }
public bool IsPublicDomain { get; set; }
public bool IsLimited { get; set; }
public bool IsLimitedUnique { get; set; }
public object Remaining { get; set; }
public int MinimumMembershipLevel { get; set; }
public int ContentRatingTypeId { get; set; }
}
use Newtonsoft.Json
var jsonString = #"{""TargetId"":0,""ProductType"":null,""AssetId"":1239281845,""ProductId"":0,""Name"":""❤️🍀𝐒𝐀𝐋𝐄❗️🍀❤️ Red&Black Flannel + Backpack"",""Description"":""Shirt Image"",""AssetTypeId"":1,""Creator"":{""Id"":124026176,""Name"":""TheDestroyerPeter"",""CreatorType"":""User"",""CreatorTargetId"":124026176},""IconImageAssetId"":0,""Created"":""2017-12-12T19:48:24.693Z"",""Updated"":""2017-12-12T19:48:24.693Z"",""PriceInRobux"":null,""PriceInTickets"":null,""Sales"":0,""IsNew"":false,""IsForSale"":false,""IsPublicDomain"":false,""IsLimited"":false,""IsLimitedUnique"":false,""Remaining"":null,""MinimumMembershipLevel"":0,""ContentRatingTypeId"":0}";
var obj = JsonConvert.DeserializeObject<RootObject>(jsonString);
Console.WriteLine(obj.Creator.Name); //"TheDestroyerPeter"

I'm trying to deserialize some JSON code in a c# applicatie. I use the DataContractJsonSerializer class to do this. All works fine, until I get nested jsonobjects,
I recieve the following json from an external API:
[{"name":"Beeldscherm","json":"{\"onHomeEnter\":{\"state\":0,\"delay\":0,\"fadeTime\":0,\"active\":false,\"updatedAt\":1487166732440},\"onHomeExit\":{\"state\":0,\"delay\":120,\"fadeTime\":0,\"active\":false,\"updatedAt\":1487163669388},\"onRoomEnter\":{\"state\":1,\"delay\":0,\"fadeTime\":0,\"active\":false,\"updatedAt\":1},\"onRoomExit\":{\"state\":0,\"delay\":120,\"fadeTime\":0,\"active\":false,\"updatedAt\":1},\"onNear\":{\"state\":1,\"delay\":0,\"fadeTime\":0,\"active\":false,\"updatedAt\":1487164911729},\"onAway\":{\"state\":0,\"delay\":2,\"fadeTime\":0,\"active\":false,\"updatedAt\":1487164909184}}","id":"58a44fa04f40b016004ffca2","sphereId":"58a44c0a4f40b016004ffc9d","createdAt":"2017-02-15T13:52:12.783Z","updatedAt":"2017-02-15T12:55:05.332Z"}]
Which I edit with the following code:
responJsonText = responJsonText.Replace("\\", "").Replace("\"{", "{").Replace("}\"", "}");
and it then looks like this:
[{"name":"Beeldscherm","json":{"onHomeEnter":{"state":0,"delay":0,"fadeTime":0,"active":false,"updatedAt":1487166732440},"onHomeExit":{"state":0,"delay":120,"fadeTime":0,"active":false,"updatedAt":1487163669388},"onRoomEnter":{"state":1,"delay":0,"fadeTime":0,"active":false,"updatedAt":1},"onRoomExit":{"state":0,"delay":120,"fadeTime":0,"active":false,"updatedAt":1},"onNear":{"state":1,"delay":0,"fadeTime":0,"active":false,"updatedAt":1487164911729},"onAway":{"state":0,"delay":2,"fadeTime":0,"active":false,"updatedAt":1487164909184}},"id":"58a44fa04f40b016004ffca2","sphereId":"58a44c0a4f40b016004ffc9d","createdAt":"2017-02-15T13:52:12.783Z","updatedAt":"2017-02-15T12:55:05.332Z"}]
and try to parse this using the following classes:
[DataContract]
class Appliance
{
[DataMember]
public String name { get; set; }
[DataMember]
public ApplianceJson json { get; set; }
[DataMember]
public String id { get; set; }
[DataMember]
public String sphereId { get; set; }
[DataMember]
public String createdAt { get; set; }
[DataMember]
public String updatedAt { get; set; }
}
[DataContract]
class ApplianceJson
{
[DataMember]
public ApplianceEvents onHomeEnter { get; set; }
[DataMember]
public ApplianceEvents onHomeExit { get; set; }
[DataMember]
public ApplianceEvents onRoomEnter { get; set; }
[DataMember]
public ApplianceEvents onRoomExit { get; set; }
[DataMember]
public ApplianceEvents onNear { get; set; }
[DataMember]
public ApplianceEvents onAway { get; set; }
}
[DataContract]
class ApplianceEvents
{
[DataMember]
public int state { get; set; }
[DataMember]
public int delay { get; set; }
[DataMember]
public int fadeTime { get; set; }
[DataMember]
public bool active { get; set; }
[DataMember]
public int updatedAt { get; set; }
}
and the following code for the deserialization:
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(List<Appliance>));
MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(responJsonText));
The error I get is:
Exception thrown: 'System.Runtime.Serialization.SerializationException' in System.Private.DataContractSerialization.dll
Exception thrown: 'System.Runtime.Serialization.SerializationException' in mscorlib.ni.dll
Does anybody see something that is wrong and how I could fix it?
Update
I checked the json string and its correct now, I've put the correct version in the question
Update 2
added the original JSON

if you notice the Original Json, You can see " is not \" but if you go deep into json, the Json Node itself has " as \". So i cleaned up all \" first and then again replaced " with \" Used Newtonsoft Json and then it parsed successfully. See my answer.
Using This Site and your JsonString, Below are the proper Json Class Structure that I created.
public class Appliance
{
public string name { get; set; }
public Json json { get; set; }
public string id { get; set; }
public string sphereId { get; set; }
public string createdAt { get; set; }
public string updatedAt { get; set; }
}
public class OnHomeEnter
{
public int state { get; set; }
public int delay { get; set; }
public int fadeTime { get; set; }
public bool active { get; set; }
public long updatedAt { get; set; }
}
public class OnHomeExit
{
public int state { get; set; }
public int delay { get; set; }
public int fadeTime { get; set; }
public bool active { get; set; }
public long updatedAt { get; set; }
}
public class OnRoomEnter
{
public int state { get; set; }
public int delay { get; set; }
public int fadeTime { get; set; }
public bool active { get; set; }
public int updatedAt { get; set; }
}
public class OnRoomExit
{
public int state { get; set; }
public int delay { get; set; }
public int fadeTime { get; set; }
public bool active { get; set; }
public int updatedAt { get; set; }
}
public class OnNear
{
public int state { get; set; }
public int delay { get; set; }
public int fadeTime { get; set; }
public bool active { get; set; }
public long updatedAt { get; set; }
}
public class OnAway
{
public int state { get; set; }
public int delay { get; set; }
public int fadeTime { get; set; }
public bool active { get; set; }
public long updatedAt { get; set; }
}
public class Json
{
public OnHomeEnter onHomeEnter { get; set; }
public OnHomeExit onHomeExit { get; set; }
public OnRoomEnter onRoomEnter { get; set; }
public OnRoomExit onRoomExit { get; set; }
public OnNear onNear { get; set; }
public OnAway onAway { get; set; }
}
Once Done, I used Json.Net
to Parse the JsonString to Appliance Object
Below is the Final Json String and Parser.
"[{\"name\":\"Beeldscherm\",\"json\":{\"onHomeEnter\":{\"state\":0,\"delay\":0,\"fadeTime\":0,\"active\":false,\"updatedAt\":1487166732440},\"onHomeExit\":{\"state\":0,\"delay\":120,\"fadeTime\":0,\"active\":false,\"updatedAt\":1487163669388},\"onRoomEnter\":{\"state\":1,\"delay\":0,\"fadeTime\":0,\"active\":false,\"updatedAt\":1},\"onRoomExit\":{\"state\":0,\"delay\":120,\"fadeTime\":0,\"active\":false,\"updatedAt\":1},\"onNear\":{\"state\":1,\"delay\":0,\"fadeTime\":0,\"active\":false,\"updatedAt\":1487164911729},\"onAway\":{\"state\":0,\"delay\":2,\"fadeTime\":0,\"active\":false,\"updatedAt\":1487164909184}},\"id\":\"58a44fa04f40b016004ffca2\",\"sphereId\":\"58a44c0a4f40b016004ffc9d\",\"createdAt\":\"2017 - 02 - 15T13: 52:12.783Z\",\"updatedAt\":\"2017 - 02 - 15T12: 55:05.332Z\"}]";
And Below is how I was able to successfully Parse Json.
List<Appliance> appJson = JsonConvert.DeserializeObject<List<Appliance>>(JsonData);
Good Luck.

I am getting Json data from a web server, but when I try to deserialize it to objects, I am not getting any data. The Json string looks like this:

I am using this statement to deserialzie the Json string: Response res = (Response)JsonConvert.DeserializeObject(customerJson, (typeof(Response)));
When I stop it in the debugger, it shows "res" as data: null and success: false.
I am not getting any errors. It is just not giving me the data from the Json string.
Any help that anybody can provide to figure out why I'm not getting the data I want in "res", would be gratefully appreciated.
Thanks,
Tony

The problem is related to the accessibility level in your Response class. By default the fields, property and method are private so JsonConvert is not able to fill the properties.
Change the class as follow:
class Response
{
public bool success {get; set;}
public IList<Customer> data {get; set;}
}
And it wil works.
Another improvement is related to the JsonConvert use. To avoid the explicit cast use this type conversion: JsonConvert.DeserializeObject<T>(string) where T will be Response

Pardon any misspeaking I may do. I am just learning asp.net c#, OOP, and MVC 4.
I am using the Annotator plugin on my site and I am trying to store and retrieve the results from a data base. When a new annotation is created it sends information like this to the controller.
{
"text":"asdas sd a dasd as dasd",
"ranges":
[{
"start":"/div/p[3]",
"startOffset":195,
"end":"/div/p[3]",
"endOffset":532
}],
"quote":"Some quote that was selected.",
"UserID":"1",
"ProjectDocID":"1"
}
Now, I hoped something like this would load all the data into a nice easy object.
// GET: /Annotation/Create
public ActionResult Create(Comment comment)
{
db.Comments.Add(comment);
db.SaveChanges();
return Json(comment);
}
The model I had looked like this (and I am change it however it needs to be changed).
public class Comment
{
[Key]
public int CommentID { get; set; }
public int ProjectDocID { get; set; }
public int UserID { get; set; }
public string text { get; set; }
public string Annotation { get; set; }
public string quote { get; set; }
public string start { get; set; }
public string end { get; set; }
public string startOffset { get; set; }
public string endOffset { get; set; }
public DateTime DateCreated { get; set; }
public virtual ICollection<CommentVote> CommentVote { get; set; }
public virtual ICollection<CommentReply> CommentReply { get; set; }
public ProjectDoc ProjectDoc { get; set; }
public virtual User User { get; set; }
}
What do I need to do to get the data from the server and map it to the model. I also need to be able to send it back in the format at the top so the plugin understands it when it asks for it from the Details action in the controller.

Not sure if this is the right way to do it or not, but it lets me store it in the database and that's all that matter for the moment. I updated my model as follows.
public class Comment
{
[Key]
public int CommentID { get; set; }
public int ProjectDocID { get; set; }
public int UserID { get; set; }
public string text { get; set; }
public string quote { get; set; }
public DateTime DateCreated { get; set; }
public virtual ICollection<CommentVote> CommentVote { get; set; }
public virtual ICollection<CommentReply> CommentReply { get; set; }
public ProjectDoc ProjectDoc { get; set; }
public virtual User User { get; set; }
public List<ranges> ranges { get; set; }
}
public class ranges {
public int ID { get; set; }
public string start { get; set; }
public string end { get; set; }
public string startOffset { get; set; }
public string endOffset { get; set; }
}
This matches the JSON object I am sending in to the controller with Ajax. Once it matches exactly the controller action above works.
