I'm currently trying to read Json file (named initial_data.json) which reside in the folder DataModels in my Project folder. The problem I'm having is it won't read the file. I have tried the following code to read the file to json string (which I will use it to deserialize later, so I've tried to display it into resultTextBlock) and nothing has came out.
Here's my Json file format
{
"brands": [
{
"id": "AUD",
"name": "AUDI",
"sort": "99",
"active": true
},
{
"id": "BEN",
"name": "MERCEDES-BENZ",
"sort": "6",
"active": true
},
{
"id": "BMW",
"name": "BMW",
"sort": "7",
"active": true
},
{
"id": "CHE",
"name": "CHEVROLET",
"sort": "8",
"active": true
}
],
"models": [
{
"id": "100",
"name": "CIVIC",
"brandID": "HON",
"size": null,
"year": "-",
"active": true
},
{
"id": "101",
"name": "CRV",
"brandID": "HON",
"size": null,
"year": "-",
"active": true
},
{
"id": "102",
"name": "CRVEXI",
"brandID": "HON",
"size": null,
"year": "-",
"active": true
},
{
"id": "103",
"name": "GDYSSEY",
"brandID": "HON",
"size": null,
"year": "-",
"active": true
}
]
}
Here's my json Class
public class Brand
{
[JsonProperty("id")]
public string id { get; set; }
[JsonProperty("name")]
public string name { get; set; }
[JsonProperty("sort")]
public string sort { get; set; }
[JsonProperty("active")]
public bool active { get; set; }
[JsonProperty("path")]
public string path { get; set; }
}
public class Model
{
[JsonProperty("id")]
public string id { get; set; }
[JsonProperty("name")]
public string name { get; set; }
[JsonProperty("brandID")]
public string brandID { get; set; }
[JsonProperty("size")]
public object size { get; set; }
[JsonProperty("year")]
public string year { get; set; }
[JsonProperty("active")]
public bool active { get; set; }
}
And here's how I write my reading function
private async Task readJsonAsync()
{
// Notice that the write **IS** identical ... except for the serializer.
string content = String.Empty;
var myStream = await ApplicationData.Current.LocalFolder.OpenStreamForReadAsync(JSONFILENAME);
using (StreamReader reader = new StreamReader(myStream))
{
content = await reader.ReadToEndAsync();
}
resultTextBlock.Text = content;
}
Any help would be appreciated
think there might be some issue with the path you specified for the file name.
Please put your file in assets folder and follow the below code
var fileStream = File.OpenRead("Assets/" + "sampleJson.txt");//You can specify your file name here.
using (StreamReader reader = new StreamReader(fileStream))
{
var content = await reader.ReadToEndAsync();
}

OK. I have sent a GET request to SharePoint and received a string back:

What I ultimately want to do is create a dropdown that is populated with the SerialNumber. When the SerialNumber is selected in the dropdown, it will return the id so that I can then plug that into a GET request to retrieve the appropriate listitems.
I am trying to figure out if I need to do a foreach to create a LIST<> or something else all together.
I do have this class setup, but wasn't sure if I could use it the way I thought I could.
public class Lookup
{
string id { get; set; };
string SerialNumber { get; set; }
}
This is the final working code:
private async void GetButton_Click(object sender, RoutedEventArgs e)
{
var (authResult, message) = await Authentication.AquireTokenAsync();
ResultText.Text = message;
if (authResult != null)
{
var httpClient = new HttpClient();
HttpResponseMessage response;
var request = new HttpRequestMessage(HttpMethod.Get, geturl);
//Add the token in Authorization header
request.Headers.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", authResult.AccessToken);
response = await httpClient.SendAsync(request);
var content = await response.Content.ReadAsStringAsync();
JObject json = JObject.Parse(content);
var result = JsonConvert.DeserializeObject<SharePointListItems.RootObject>(content);
foreach (var d in result.value)
{
Lookups.Add(new SharePointListItems.Lookup() { id = d.fields.id, SerialNumber = d.fields.SerialNumber });
}
TestComboBox.ItemsSource = Lookups;
}
}
private void TestComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
if (TestComboBox.SelectedIndex != -1)
{
var mylookupId = (TestComboBox.SelectedItem as SharePointListItems.Lookup).id;// get your id and do further processing here.
ResultText.Text = mylookupId;
}
}
public class SharePointListItems
{
public class Lookup
{
public string SerialNumber { get; set; }
public string id { get; set; }
public override string ToString()
{
return SerialNumber;
}
}
public class Value
{
public Lookup fields { get; set; }
}
public class Fields
{
[JsonProperty("#odata.etag")]
public string ODataETag { get; set; }
...
}
public class RootObject
{
[JsonProperty("#odata.context")]
public string ODataContext { get; set; }
[JsonProperty("#odata.etag")]
public string ODataETag { get; set; }
[JsonProperty("fields#odata.context")]
public string FieldsODataContext { get; set; }
public Fields Fields { get; set; }
public List<Value> value { get; set; }
}
}
There are two way can create model easily.
You can use Web Essentials in Visual Studio, use Edit > Paste special > paste JSON as class, you can easier to know the relation between Json and model.
If you can't use Web Essentials you can instead of use http://json2csharp.com/ online JSON to Model class.
You can try to use those models to carry your JSON Format.
public class Lookup
{
public string SerialNumber { get; set; }
public string id { get; set; }
}
public class Value
{
public Lookup fields { get; set; }
}
public class RootObject
{
public List<Value> value { get; set; }
}
Then you can use obj.value property collection directly.
var obj = JsonConvert.DeserializeObject<RootObject>(jsonData);
foreach (var item in obj.value)
{
//item.fields.id
//item.fields.SerialNumber
}
A good example of how to bind a list of data to Combobox ( dropdown ) is here : https://www.c-sharpcorner.com/article/data-binding-in-xaml-uwp-using-combobox/
in this example the class is a Student with id and Name and it shows how u can show the name in combobox.
I will modify it a little for your scenario but if you want to go in depth than you can visit the provided link above.
This is the class
public class Fields
{
public string SerialNumber { get; set; }
public string id { get; set; }
public override string ToString()
{
return this.SerialNumber; // so that we can just bind to the object and get serial number in the ui.
}
}
Backend for adding items to the List
public sealed partial class MainPage: Page
{
List<Lookup> Lookups = new List<Lookup>();
public MainPage()
{
this.InitializeComponent();
Lookups.Add(new Lookup() {id = 1, SerialNumber = "S1"});
Lookups.Add(new Lookup() {id = 2, SerialNumber = "S2"});
Lookups.Add(new Lookup() {id = 3, SerialNumber = "S3"});
Lookups.Add(new Lookup() {id = 4, SerialNumber = "S4"});
//add as many items here as u want, u can even use a for loop or foreach loop or a Deserializer with newsoft json to get objects from ur json like below.
//var data = JsonConvert.DeserializeObject<RootObject>(jsonData);
//foreach (var d in data.value)
//{
// //d.fields.id //this is how u can get the inside properties.
//}
yourComboBox.ItemSource = Lookups;//setting item source to UI.
}
}
after you successfully bind the data with UI you can use SelectionChanged event of your combobox to do further logic as you require,
void MyComboBox_SelectionChanged(object sender, object args)
{
if(MyCombobox.SelectedIndex!=-1)
{
var mylookupId = (MyCombobox.SelectedItem as Lookup).id;// get your id and do further processing here.
}
}
I think this will be easy when using newtonsoft:
var dynamicObject = JObject.Parse(yourstring);
var list = new List<Lookup>();
//now you have a dynamic object containing an array.
//this should be doable with linq as well.
//note, the type is dynamic
foreach (dynamic thing in dynamicObject )
{
list.Add(new Lookup()
{
id = thing.fields.id,
SerialNumber = thing.fields.SerialNumber
});
}
disclaimer: not tested in any way ;-)
I tried to send a Dictionary.
This is the structure of my Dictionary:
var gridsAndCountriesByShipper = new Dictionary<Organisation, List<Grid>>();
And this is the class which the namespace appears instead of the object value:
namespace ez.webservice.PublicRestApi.DTO.References
{
[DataContract(Name = "organisation", Namespace = "")]
public class Organisation
{
[DataMember(Name = "id")]
public int Id { get; set; }
[DataMember(Name = "longName")]
public string LongName { get; set; }
[DataMember(Name = "shortName")]
public string ShortName { get; set; }
}
}
Finally this is the result when I send this object:
return Ok(gridsAndCountriesByShipper);
{
"ez.webservice.PublicRestApi.DTO.References.Organisation": [
{
"owner": {
"$id": "1",
"id": 2,
"longName": null,
"shortName": "Test"
},
"calendar": {
"id": 3,
"name": null,
"dotNetName": null,
"mySqlName": null,
"offset": 0
},
"country": {
"id": 13,
"name": "France",
"alpha2": "FR",
"alpha3": "FRA",
"grids": [],
"logo": {
"id": 13,
"name": "France",
"shortName": "FR"
}
},
"countryFlag": null,
"flag": "",

I didn't find a solution.
Your Organisation doesn't override ToString() method and the default behavior is to return the class name with namespace
im facing a problem with probably selfreference Looping:
Model:
public class ProtectedAccount
{
public int Id { get; set; }
[DatabaseGenerated(DatabaseGeneratedOption.Computed)]
public DateTime Created { get; private set; }
public DateTime? Changed { get; set; }
public bool Disabled { get; set; }
public virtual ICollection<ProtectedAccountMember> Members { get; set; }
public virtual ProtectedAccountType Type { get; set; }
}
public class ProtectedAccountMember
{
public int Id { get; set; }
[StringLength(300)]
public string Name { get; set; }
[Index]
public virtual ProtectedAccount ProtectedAccount { get; set; }
}
Controller:
[ResponseType(typeof(ProtectedAccount))]
[Route("ProtectedAccounts/{id}/Members")]
[HttpGet]
public IHttpActionResult GetProtectedAccountMembers(int id)
{
var protectedAccount = db.ProtectedAccounts.Find(id);
if (protectedAccount == null)
{
return NotFound();
}
return Ok(protectedAccount.Members.ToList());
}
the data wich i receive for an GET seems to Loop recursive through all navigations:
[
{
"ProtectedAccount": {
"Members": [
{
"Id": 2,
"Name": "XXX, XX",
},
{
"Id": 3,
"Name": "XX, XX",
}
],
"Type": null,
"Id": 25,
"ObjectGUID": "76bf65e7-af60-4fe8-b3e1-90afbfd65b65",
"Name": "XXX",
},
"Id": 1,
"Name": "test",
},
{
"ProtectedAccount": {
"Members": [
{
"Id": 1,
"Name": "test",
},
{
"Id": 3,
"Name": "XX, XX",
"SamAccountName": "XX",
"Disabled": false
}
],
"Type": null,
"Id": 25,
"ObjectGUID": "76bf65e7-af60-4fe8-b3e1-90afbfd65b65",
"Name": "XXXX",
},
"Id": 2,
"Name": "XX, XX",
},
{
"ProtectedAccount": {a
"Members": [
{
"Id": 1,
"Name": "test",
"SamAccountName": "XXX",
"Disabled": false
},
{
"Id": 2,
"Name": "XX, XX",
"SamAccountName": "XX",
"Disabled": false
}
],
"Type": null,
"Id": 25,
"ObjectGUID": "76bf65e7-af60-4fe8-b3e1-90afbfd65b65",
"Name": "XXX",
},
"Id": 3,
"Name": "XX, XX",
}
]
There is only one "ProtectedAccount" in the database. DO i have to use DTO to overcome this issue? I tried some configuration via the json formatsettings but didnt get any better results.
From your code, you are only returing the protectedAccount.Members, hence you could do a projection query as below
var results = ctx.ProtectedAccountMembers
.Where(member => member.ProtectedAccount.Id == protectedAccount.Id)
.Select(member => new { member.Id, member.Name }).ToList();
I'm trying to deserialize a json string and I'm getting the error End element 'caption' from namespace '' expected. Found element 'created_time' from namespace ''. when calling
InstagramObject test = (InstagramObject) instagramObject.ReadObject(instagramWebResponse.GetResponseStream());
The json from Instagram returns many elements but there are only a few that I need. My DataContract will be posted below.
Basically I need {data:[{caption: string, link: string, images: {...}}]}
Here's an example of the json...
{
"data": [{
"comments": {
"data": [],
"count": 0
},
"caption": {
"created_time": "1296710352",
"text": "Inside le truc #foodtruck",
"from": {
"username": "kevin",
"full_name": "Kevin Systrom",
"type": "user",
"id": "3"
},
"id": "26621408"
},
"likes": {
"count": 15,
"data": [{
"username": "mikeyk",
"full_name": "Mike Krieger",
"id": "4",
"profile_picture": "..."
}, {...subset of likers...}]
},
"link": "http://instagr.am/p/BWrVZ/",
"user": {
"username": "kevin",
"profile_picture": "http://distillery.s3.amazonaws.com/profiles/profile_3_75sq_1295574122.jpg",
"id": "3"
},
"created_time": "1296710327",
"images": {
"low_resolution": {
"url": "http://distillery.s3.amazonaws.com/media/2011/02/02/6ea7baea55774c5e81e7e3e1f6e791a7_6.jpg",
"width": 306,
"height": 306
},
"thumbnail": {
"url": "http://distillery.s3.amazonaws.com/media/2011/02/02/6ea7baea55774c5e81e7e3e1f6e791a7_5.jpg",
"width": 150,
"height": 150
},
"standard_resolution": {
"url": "http://distillery.s3.amazonaws.com/media/2011/02/02/6ea7baea55774c5e81e7e3e1f6e791a7_7.jpg",
"width": 612,
"height": 612
}
},
"type": "image",
"filter": "Earlybird",
"tags": ["foodtruck"],
"id": "22721881",
"location": {
"latitude": 37.778720183610183,
"longitude": -122.3962783813477,
"id": "520640",
"street_address": "",
"name": "Le Truc"
}
}]
}
and here's my DataContract...
[DataContract]
public class InstagramObject {
[DataMember(Name = "data")]
public IEnumerable<InstagramData> instagramData { get; set; }
}
[DataContract]
public class InstagramData {
[DataMember(Name = "images")]
public List<InstagramImage> instagramImages { get; set; }
[DataMember(Name = "caption")]
public string caption { get; set; }
[DataMember(Name = "link")]
public string link { get; set; }
}
[DataContract]
public class InstagramImage {
[DataMember(Name = "low_resolution")]
public InstagramImageInfo lowResolutionImage { get; set; }
[DataMember(Name = "thumbnail")]
public InstagramImageInfo thumbnail { get; set; }
[DataMember(Name = "standard_resolution")]
public InstagramImageInfo standardResolution { get; set; }
}
[DataContract]
public class InstagramImageInfo {
[DataMember(Name = "url")]
public string url { get; set; }
[DataMember(Name = "width")]
public int width { get; set; }
[DataMember(Name = "height")]
public int height { get; set; }
}
In the data contract caption is declared as a string, but in the JSON caption is a record with various fields - caption should be declared to be an object with a compatible structure:
[DataContract]
public class InstagramCaption {
[DataMember(Name = "text")]
public string Text {get; set;}
}
. . .
[DataMember(Name = "caption")]
public InstagramCaption caption { get; set; }
. . .
No need to declare those clases If you want to go with Json.Net + Linq
var obj = (JObject)JsonConvert.DeserializeObject(json);
var result = obj["data"]
.Select(x => new {
Caption = (string)x["caption"]["text"],
Link = (string)x["link"],
Images = x["images"].Children()
.Select(y=>(string)y.First()["url"]).ToArray()
})
.ToArray();
I have the following JSon:
{ "Test": {"Header": {"Description": "OK", "Status": "000", "Timestamp": "1338805752" }, "Results": {"Sport": {"Country": { "League": [ {"Name": "ECB 40 League", "TargetURL": "\/Cricket\/International\/ECB 40 League", "Total": "5" }, {"Name": "Friends Life T20 2012", "TargetURL": "\/Cricket\/International\/Friends Life T20 2012", "Total": "0" }, {"Name": "Sri Lanka vs Pakistan (ODI Series)", "TargetURL": "\/Cricket\/International\/Sri Lanka vs Pakistan (ODI Series)", "Total": "0" }, {"Name": "Sri Lanka vs Pakistan 1st ODI", "TargetURL": "\/Cricket\/International\/Sri Lanka vs Pakistan 1st ODI", "Total": "1" }, {"Name": "Test Series", "TargetURL": "\/Cricket\/International\/Test Series", "Total": "1" } ], "Name": "International", "TargetURL": "\/Cricket\/International", "Total": "6" }, "Name": "Cricket", "Total": "5" } } }}
And when I return it from my C# Code, I get it this way:
<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">{ "HotOdds": {"Header": {"Description": "OK", "Status": "000", "Timestamp": "1338805752" }, "Results": {"Sport": {"Country": { "League": [ {"Name": "ECB 40 League", "TargetURL": "\/Cricket\/International\/ECB 40 League", "Total": "5" }, {"Name": "Friends Life T20 2012", "TargetURL": "\/Cricket\/International\/Friends Life T20 2012", "Total": "0" }, {"Name": "Sri Lanka vs Pakistan (ODI Series)", "TargetURL": "\/Cricket\/International\/Sri Lanka vs Pakistan (ODI Series)", "Total": "0" }, {"Name": "Sri Lanka vs Pakistan 1st ODI", "TargetURL": "\/Cricket\/International\/Sri Lanka vs Pakistan 1st ODI", "Total": "1" }, {"Name": "Test Series", "TargetURL": "\/Cricket\/International\/Test Series", "Total": "1" } ], "Name": "International", "TargetURL": "\/Cricket\/International", "Total": "6" }, "Name": "Cricket", "Total": "5" } } }}</string>
Here is the function's definition:
[OperationContract(Name = "GetHOSports")]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
string GetSportsList(DateTime date, int sportID);
I dont get why I am getting the JSON inside XML element, anyone?.
Have you done the serialization:
TestRootObject testRootObject = new TestRootObject();
......................
..............YOUR CODE..............
..................
System.Web.Script.Serialization.JavaScriptSerializer oSerializer =
new System.Web.Script.Serialization.JavaScriptSerializer();
return oSerializer.Serialize(testRootObject);
Your C# Classes:
public class Header
{
public string Description { get; set; }
public string Status { get; set; }
public string Timestamp { get; set; }
}
public class League
{
public string Name { get; set; }
public string TargetURL { get; set; }
public string Total { get; set; }
}
public class Country
{
public List<League> League { get; set; }
public string Name { get; set; }
public string TargetURL { get; set; }
public string Total { get; set; }
}
public class Sport
{
public Country Country { get; set; }
public string Name { get; set; }
public string Total { get; set; }
}
public class Results
{
public Sport Sport { get; set; }
}
public class Test
{
public Header Header { get; set; }
public Results Results { get; set; }
}
public class TestRootObject
{
public Test Test { get; set; }
}
You shouldn't return a string with json return the object you want serialized to json. You should also be able to remove ResponseFormat it's default setting is json.
Have a look at this answer: [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
Explains how to get your script method working.
If you don't have the object model to serialize this from your going to have a hard time using WCF. It's designed around the principle of serializing .net objects to json or xml.
If you have json strings I would go with something like Nancy which gives you much more freedom to do things as you like :), which includes if you want json strings.
A nancy module for somehting like this would look like this:
public class SampleModule : Nancy.NancyModule
{
public SampleModule()
{
Get["/GetHOSports"] = parameters => {
Response.ContentType = "application/json"
Response.Content = s => {
var sw = new StreamWriter(s) { AutoFlush = true };
sw.Write("your json here");
}
}
}
}
