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.
So I created a class using json2csharp
public class ResponseType
{
public class Query
{
public string q { get; set; }
public object sku { get; set; }
public int limit { get; set; }
public object reference { get; set; }
public object mpn_or_sku { get; set; }
public string mpn { get; set; }
public object brand { get; set; }
public string __class__ { get; set; }
public int start { get; set; }
public object seller { get; set; }
}
public class Request
{
public bool exact_only { get; set; }
public string __class__ { get; set; }
public List<Query> queries { get; set; }
}
public class Seller
{
public string display_flag { get; set; }
public bool has_ecommerce { get; set; }
public string name { get; set; }
public string __class__ { get; set; }
public string homepage_url { get; set; }
public string id { get; set; }
public string uid { get; set; }
}
public class Prices
{
public List<List<object>> USD { get; set; }
public List<List<object>> JPY { get; set; }
public List<List<object>> CNY { get; set; }
}
public class Offer
{
public string sku { get; set; }
public string packaging { get; set; }
public string on_order_eta { get; set; }
public string last_updated { get; set; }
public int? order_multiple { get; set; }
public int in_stock_quantity { get; set; }
public string eligible_region { get; set; }
public int? moq { get; set; }
public int? on_order_quantity { get; set; }
public object octopart_rfq_url { get; set; }
public string __class__ { get; set; }
public Seller seller { get; set; }
public string product_url { get; set; }
public object factory_order_multiple { get; set; }
public string _naive_id { get; set; }
public int? factory_lead_days { get; set; }
public Prices prices { get; set; }
public bool is_authorized { get; set; }
public bool is_realtime { get; set; }
}
public class Brand
{
public string homepage_url { get; set; }
public string __class__ { get; set; }
public string name { get; set; }
public string uid { get; set; }
}
public class Manufacturer
{
public string homepage_url { get; set; }
public string __class__ { get; set; }
public string name { get; set; }
public string uid { get; set; }
}
public class Item
{
public List<Offer> offers { get; set; }
public string uid { get; set; }
public string mpn { get; set; }
public List<object> redirected_uids { get; set; }
public Brand brand { get; set; }
public string octopart_url { get; set; }
public string __class__ { get; set; }
public Manufacturer manufacturer { get; set; }
}
public class Result
{
public List<Item> items { get; set; }
public int hits { get; set; }
public string __class__ { get; set; }
public object reference { get; set; }
public object error { get; set; }
}
public class RootObject
{
public int msec { get; set; }
public Request request { get; set; }
public string __class__ { get; set; }
public List<Result> results { get; set; }
}
}
The problem is at design-time, when I declare a variable with the type of my class:
ResponseType Response = new ResponseType();
Intellisense does not allow me to access the subclasses RootObject.results list. It only shows Equals, GetHashCode, GetType and ToString. I am assuming I did something wrong in my class declaration.
Thank you in advance!
Edit -- I am fairly new to C Sharp. I am trying to parse a response from a REST API. I took the JSON provided by the Rest API and converted it using json2csharp into a class. My intent was to do something like this
Within a function return:
public ResponseType ExecuteSearch(String PartNumber)
{
~ ALL CODE FOR GENERATING req
// Perform the search and obtain results
var data = client.Execute(req).Content;
JSON = data;
return JsonConvert.DeserializeObject<ResponseType>(data);
}
Then being able to access the response as an object outside of the function
Edit 2:
I figured out what I did. Instead of nesting everything within the ResponseType I should have simply renamed RootObject to ResponseType.
Intellisense does not allow me to access the subclasses RootObject.results list
it is because the property results is not static and you try to acces it this way. A static property is accessed via ClassName.PropertyName. For more information on static variables check the link.
It only shows Equals, GetHashCode, GetType and ToString
This is the basic set of methods that every object in C# inherits from the class object. This is why you can see it.
Intellisense will allow you to do this:
ResponseType.RootObject ro = new ResponseType.RootObject();
ro.results.First();
because you will need an Instance of that class to acces the property results.
I am assuming I did something wrong in my class declaration.
It depends. Basically if the compiler does not complain then you declared your classes as supposed to be. But the declaration of the properties commands you to access them in a specific way. So if you still want to access results with RootObject.results you need to make it static:
public class RootObject
{
public static List<Result> results { get; set; }
}
But note that this list will exist only once! and is not individual to each instance of RootObject! Since you have embedded classes you need to call it like this:
ResponseType.RootObject.results.WhatEver();
EDIT
I guess you would like to get the Object of type RootObject inside the Object of type ResponseType. If I am right then it is not necessary to declare the classes inside ResponseType but you have to declare variables of each type inside it like:
public class ResponseType
{
public RootObject MyRootObject{ get; set; }
}
public class RootObject
{
public int msec { get; set; }
public Request request { get; set; }
public string __class__ { get; set; }
public List<Result> results { get; set; }
}
Now you will be able to access the results variable inside the ResponseType object:
ResponseType rt = new ResponseType();
rt.MyRootObject.results.WhatEver();
For more information on how to deserialize JSON to classes please read the Deserialize JSON to C# Classes post
1) Object with ResponseType class isn't contain any fields(event static one).
2) You declare ResponseType object, but results is field of RootObject object.
So if you want to work with results you should do something like this:
ResponseType.RootObject rootObject = new ResponseType.RootObject();
rootObject.results.DoWork();
Below is what I think you are trying to do. I would only use it in this form if this is some kind of Data Transfer Object (DTO) because otherwise it is pretty bad practice for a class that would be used in code (mostly because of the public getters and setters on all of the fields and the field names matching the class name), but it does show your main mistake and that is that classes need to be defined outside of your main class and if you need that type of class in your top level class you need to define a public field to access it.

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 created these classes from the recommendation given in this link:
recommendation
I used this to create the classes: json2csharp
Response class:
class Response
{
bool success;
IList<Customer> data;
}
Customer class:
class Customer
{
public int Id { get; set; }
public string CustomerGuid { get; set; }
public string UserName { get; set; }
public string Email { get; set; }
public List<CustomerRole> CustomerRoles { get; set; }
public object AdminComment { get; set; }
public bool IsTaxExempt { get; set; }
public int AffiliateId { get; set; }
public int VendorId { get; set; }
public bool HasShoppingCartItems { get; set; }
public bool Active { get; set; }
public bool Deleted { get; set; }
public bool IsSystemAccount { get; set; }
public object SystemName { get; set; }
public string LastIpAddress { get; set; }
public DateTime CreatedOnUtc { get; set; }
public DateTime? LastLoginDateUtc { get; set; }
public DateTime LastActivityDateUtc { get; set; }
public List<object> ExternalAuthenticationRecords { get; set; }
public List<object> ShoppingCartItems { get; set; }
}
CustomerRole class:
class CustomerRole
{
public int Id { get; set; }
public string Name { get; set; }
public string SystemName { get; set; }
}
ExternalAuthenticationRecord class:
class ExternalAuthenticationRecord
{
public int Id { get; set; }
public int CustomerId { get; set; }
public string Email { get; set; }
public object ExternalIdentifier { get; set; }
public object ExternalDisplayIdentifier { get; set; }
public object OAuthToken { get; set; }
public object OAuthAccessToken { get; set; }
public string ProviderSystemName { get; set; }
}
ShoppingCartItem class:
class ShoppingCartItem
{
public int Id { get; set; }
public int StoreId { get; set; }
public int ShoppingCartTypeId { get; set; }
public int CustomerId { get; set; }
public int ProductId { get; set; }
public object AttributesXml { get; set; }
public double CustomerEnteredPrice { get; set; }
public int Quantity { get; set; }
public DateTime CreatedOnUtc { get; set; }
public DateTime UpdatedOnUtc { get; set; }
public bool IsFreeShipping { get; set; }
public bool IsShipEnabled { get; set; }
public double AdditionalShippingCharge { get; set; }
public bool IsTaxExempt { get; set; }
}
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
Found an odd issue when trying to deserialize a JSON string into a C# Object. It "seems" to perform the operation successfully (as in it does not throw any exception etc), however the outputted POCO contains does not contain any data from the JSON string, it only contains type default data (nulls,"", 0 etc). I have tried this process with other JSON and it works fine.

Any ideas - Im sure I have missed something glaringly obvious but I cannot see it. Using .NET 4.5
Help appreciated.
Cheers
I used http://json2csharp.com/, and the code is like this, so you should look at it.

Look like you JSON string is not in correct format that you are trying to deserialize. For example i have not find show property in the C# class but it present in JSON.
So this issue I couldn't figure out in the night or early in the morning - it took me till this afternoon until I realised that I was had the wrong JSON!!, so no wonder it wasn't working! I got mixed up with a few different apis that provided JSON. Thanks to those who had pointed out that the class looks wrong, made me double check my code and realise the simplicity of this issue. Kinda needed some rubber ducking to spot the problem. Cheers
I am trying to deserialize an object, the type is populated but I am getting null for the List<Sport>. Any ideas?
My classes:
class Sports
{
public MsgTypes type { get; set; }
public List<Sport> Sport { get; set; }
}
class Sport
{
public int Id { get; set; }
public int Import_id { get; set; }
public string Name { get; set; }
public int Active { get; set; }
public int Order { get; set; }
public int Min_bet { get; set; }
public int Max_bet { get; set; }
public int Updated { get; set; }
public string Feed_type { get; set; }
public string Locale { get; set; }
}
The command for deserialization:
Sports _sports = (Sports) JsonConvert.DeserializeObject<Sports>(jsonObj);
This is my JSON object:
"{\"code\":0,\"type\":4,\"Sports\":[{\"Sport\":{\"id\":\"1\",\"import_id\":\"1\",\"name\":\"Soccer\",\"active\":true,\"order\":\"1\",\"min_bet\":\"0\",\"max_bet\":\"0\",\"updated\":\"1403194889\",\"feed_type\":\"Betradar\",\"locale\":\"en_us\"}},{\"Sport\":{\"id\":\"2\",\"import_id\":\"5\",\"name\":\"Tennis\",\"active\":true,\"order\":\"3\",\"min_bet\":\"0\",\"max_bet\":\"0\",\"updated\":\"1403194771\",\"feed_type\":\"Betradar\",\"locale\":\"en_us\"}},{\"Sport\":{\"id\":\"3\",\"import_id\":\"6\",\"name\":\"Handball\",\"active\":true,\"order\":\"6\",\"min_bet\":\"0\",\"max_bet\":\"0\",\"updated\":\"1403152901\",\"feed_type\":\"Betradar\",\"locale\":\"en_us\"}},{\"Sport\":{\"id\":\"4\",\"import_id\":\"4\",\"name\":\"Ice Hockey\",\"active\":true,\"order\":\"4\",\"min_bet\":\"0\",\"max_bet\":\"0\",\"updated\":\"1403080245\",\"feed_type\":\"Betradar\",\"locale\":\"en_us\"}},{\"Sport\":{\"id\":\"7\",\"import_id\":\"2\",\"name\":\"Basketball\",\"active\":true,\"order\":\"2\",\"min_bet\":\"0\",\"max_bet\":\"0\",\"updated\":\"1403194830\",\"feed_type\":\"Betradar\",\"locale\":\"en_us\"}},{\"Sport\":{\"id\":\"8\",\"import_id\":\"23\",\"name\":\"Volleyball\",\"active\":true,\"order\":\"5\",\"min_bet\":\"0\",\"max_bet\":\"0\",\"updated\":\"1403194591\",\"feed_type\":\"Betradar\",\"locale\":\"en_us\"}},{\"Sport\":{\"id\":\"9\",\"import_id\":\"12\",\"name\":\"Rugby\",\"active\":true,\"order\":\"7\",\"min_bet\":\"0\",\"max_bet\":\"0\",\"updated\":\"1403194710\",\"feed_type\":\"Betradar\",\"locale\":\"en_us\"}},{\"Sport\":{\"id\":\"12\",\"import_id\":\"11\",\"name\":\"Motorsport\",\"active\":true,\"order\":\"12\",\"min_bet\":\"0\",\"max_bet\":\"0\",\"updated\":\"1403065699\",\"feed_type\":\"Betradar\",\"locale\":\"en_us\"}},{\"Sport\":{\"id\":\"13\",\"import_id\":\"3\",\"name\":\"Baseball\",\"active\":true,\"order\":\"13\",\"min_bet\":\"0\",\"max_bet\":\"0\",\"updated\":\"1403194834\",\"feed_type\":\"Betradar\",\"locale\":\"en_us\"}},{\"Sport\":{\"id\":\"14\",\"import_id\":\"16\",\"name\":\"American Football\",\"active\":true,\"order\":\"14\",\"min_bet\":\"0\",\"max_bet\":\"0\",\"updated\":\"1403143326\",\"feed_type\":\"Betradar\",\"locale\":\"en_us\"}},{\"Sport\":{\"id\":\"16\",\"import_id\":\"34\",\"name\":\"Beach Volley\",\"active\":true,\"order\":\"16\",\"min_bet\":\"0\",\"max_bet\":\"0\",\"updated\":\"1403194417\",\"feed_type\":\"Betradar\",\"locale\":\"en_us\"}}]}"
You need one more level of nesting and different class names. You should be able to deserialize to such structure:
class SportsParent
{
//Code for MsgTypes was not provided so it is commented out
public List<SportGroup> Sports { get; set; }
}
class SportGroup
{
public SportItem Sport { get; set; }
}
class SportItem
{
public int Id { get; set; }
public int Import_id { get; set; }
public string Name { get; set; }
public bool Active { get; set; } //need to be converted to bool instead of int
public int Order { get; set; }
public int Min_bet { get; set; }
public int Max_bet { get; set; }
public int Updated { get; set; }
public string Feed_type { get; set; }
public string Locale { get; set; }
}
You can deserialize using such code:
SportsParent _sports = JsonConvert.DeserializeObject<SportsParent>(jsonObj);
