C# - How convert json string to class

How can I convert my json-string to class

this is my json

{
"$id": "1",
"Result": {
"$id": "2",
"dateTime": 23821964,
"list": [{
"$id": "3",
"UserId": 302,
"UID": "302_UID",
"Title": "شیدکو",
"Sender": "شیدکو",
"Answer": "",
"Comment": "test 2",
"ProductTitle": null,
"CommentId": 77,
"Logo": "http://www.asankharid.ir/persianCommercial/User/302/Logo/tmpF0BF.jpg",
"Date": 24302057,
"AnswerDate": -2123661683,
"AnswerEdit": false,
"CommentEdit": false,
"ForfeitCount": 0,
"RewardCount": 0,
"ThisCountReport": 2,
"Reported": [{
"$id": "4",
"BlockerId": 355,
"Title": "محتوای غیر اخلاقی",
"Date": -19527396,
"ForfeitCount": 0,
"RewardCount": 0
}, {
"$id": "5",
"BlockerId": 355,
"Title": "محتوای غیر مرتبط",
"Date": -19527382,
"ForfeitCount": 0,
"RewardCount": 0
}],
"Gem": 0
}, {
"$id": "6",
"UserId": 302,
"UID": "302_UID",
"Title": "شیدکو",
"Sender": "شیدکو",
"Answer": "",
"Comment": "test 2",
"ProductTitle": null,
"CommentId": 77,
"Logo": "http://www.asankharid.ir/persianCommercial/User/302/Logo/tmpF0BF.jpg",
"Date": 24302057,
"AnswerDate": -2123661683,
"AnswerEdit": false,
"CommentEdit": false

}]

},
"StatusCode": "Created",
"Description": null
}


And I do these step, but nothing happens

JObject json1 = JObject.Parse(strMyJson);
_CommentAdmindto flight = Newtonsoft.Json.JsonConvert.DeserializeObject<_CommentAdmindto>(json1.ToString());
_CommentAdmindto deserializedProduct = JsonConvert.DeserializeObject<_CommentAdmindto>(json);
_CommentAdmindto deserializedProduct1 = ConvertJsonToClass<_CommentAdmindto>(strMyJson);
JsonSerializer serializer = new JsonSerializer();
_CommentAdmindto p = (_CommentAdmindto)serializer.Deserialize(new JTokenReader(strMyJson), typeof(_CommentAdmindto));


And here is my class and function:

public static T ConvertJsonToClass<T>( string json)
{
System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
return serializer.Deserialize<T>(json);
}

}



public class _CommentAdmindto
{
public long dateTime { get; set; }

public IQueryable<CommentDtoAdmin> list { get; set; }


}


public class CommentDtoAdmin
{
public long UserId { get; set; }
public string UID { get; set; }
public string Title { get; set; }
public string Sender { get; set; }
public string Answer { get; set; }
public string Comment { get; set; }

public string ProductTitle { get; set; }
public long CommentId { get; set; }

public string Logo { get; set; }
public long Date { get; set; }

public long AnswerDate { get; set; }

public bool AnswerEdit { get; set; }

public bool CommentEdit { get; set; }


}

Answer

You seem to be trying to deserialize in a lot of different ways but you don't have a full structure to actually match the json. You miss the outer class (representing the full object) and at least Newtonsoft.Json cannot deserialize to an IQueryable so I changed that to IEnumerable.

string strMyJson = "{\"$id\":\"1\",\"Result\":{\"$id\":\"2\",\"dateTime\":23826985,\"list\":[{\"$id\":\"3\",\"UserId\":302,\"UID\":\"302_UID\",\"Title\":\"شیدکو\",\"Sender\":\"شیدکو\",\"Answer\":\"\",\"Comment\":\"test 2\",\"ProductTitle\":null,\"CommentId\":77,\"Logo\":\"http://www.domain.com/Commercial/User/302/Logo/tmpF0BF.jpg\",\"Date\":24307078,\"AnswerDate\":-2123656662,\"AnswerEdit\":false,\"CommentEdit\":false,\"ForfeitCount\":0,\"RewardCount\":0,\"ThisCountReport\":2,\"Reported\":[{\"$id\":\"4\",\"BlockerId\":355,\"Title\":\"محتوای غیر اخلاقی\",\"Date\":-19527396,\"ForfeitCount\":0,\"RewardCount\":0},{\"$id\":\"5\",\"BlockerId\":355,\"Title\":\"محتوای غیر مرتبط\",\"Date\":-19527382,\"ForfeitCount\":0,\"RewardCount\":0}],\"Gem\":0},{\"$id\":\"6\",\"UserId\":302,\"UID\":\"302_UID\",\"Title\":\"شیدکو\",\"Sender\":\"شیدکو\",\"Answer\":\"\",\"Comment\":\"test 2\",\"ProductTitle\":null,\"CommentId\":77,\"Logo\":\"http://www.domain.com/Commercial/User/302/Logo/tmpF0BF.jpg\",\"Date\":24307078,\"AnswerDate\":-2123656662,\"AnswerEdit\":false,\"CommentEdit\":false}],\"StatusCode\":\"Created\",\"Description\":null}}";


var result = JsonConvert.DeserializeObject<Wrapper>(strMyJson);

with classes looking like this:

public class Wrapper
{
    public _CommentAdmindto Result { get; set; }
}
public class _CommentAdmindto
{
    public long dateTime { get; set; }

    public IEnumerable<CommentDtoAdmin> list { get; set; }
}

CommentDtoAdmin is looking the same. Though I must say that this only helps you with the deserialization.
