如何在Windows Phone 8.1中反序列化json对象？

Question

I want to bind json obect to my properties When I deserialize the json object and bind into the properties ,properties shows null values,please some one help me to resolve this.

this is my code

string s = "{\"response\":{\"status\":\"fail\",\"content\":{\"user_id\":\"56\",\"first\":\"kiran\",\"last\":\"kumar\",\"username\":\"kirankumar\"},\"msg\":\"shggh\"}}";

var jsonObj = JObject.Parse(s);

response myDeserializedObj = (response)Newtonsoft.Json.JsonConvert.DeserializeObject(jsonObj.ToString(), typeof(response));

this is properties

public class response
{
    public string status { get; set; }
    public content content { get; set; }
}

public class content
{
    public string user_id { get; set; }
    public string first { get; set; }
    public string last { get; set; }
    public string username { set; get; }
}

Thanks, karthik

Answer 1

I copied you code and tested it in my machine and I could solve your problem here is the solution

add the following class

public class ResponseWrapper
{
    public response response { get; set; }
}

replace your code with the following

string s = "{\"response\":{\"status\":\"fail\",\"content\":{\"user_id\":\"56\",\"first\":\"kiran\",\"last\":\"kumar\",\"username\":\"kirankumar\"},\"msg\":\"shggh\"}}";

response my = JsonConvert.DeserializeObject<ResponseWrapper>(s).response;

I am sure this will work.

UPDATE

Another solution (Which is tested also) and better than the first one because it is more clean, and in this way you have not to create new wrapper class.

the solution is replace your string with the following string.

and all of your previous code will stay the same here is the correct JSON string

string s = "{\"status\":\"fail\",\"content\":{\"user_id\":\"56\",\"first\":\"kiran\",\"last\":\"kumar\",\"username\":\"kirankumar\"},\"msg\":\"shggh\"}";

UPDATE 2

in the comments below of this answer you asked a completely a new question. here is your new question (I copied this from your comments)

public class responseWraper
{
    public response response { get; set; }
}

public class response
{
    public string status { get; set; }
    public content content { get; set; }
}

public class content
{
    public Employees Employees { get; set; }
}

public class Employees
{
    public string Employee_id { get; set; }
    public string Employee_name { get; set; }
    public string status { get; set; }
}      

and here is how you are trying to deserialize this (also this copied from your comments)

string s = "{\"response\":{\"status\":\"success\",\"content\":{\"Employees\":[{\"Employee_i‌​d\":\"1\",\"Employee_name\":\"Sravan\",\"status\":\"1\"},}]}}}"; 
response my = Newtonsoft.Json.JsonConvert.DeserializeObject<responseWraper>(s).response;

ANSWER your code has two problem

the first is you are using the Employees as array in the JSON string, but the type of the Employees property is not an array

the second problem that the JSON string itself is not valid. it has an errors there is 4 { character but you have 5 } character inside it.

so you have to fix those two problem as the following

public class content
{
    public List<Employees> Employees { get; set; }
}

and the string is

 string s = "{\"response\":{\"status\":\"success\",\"content\":{\"Employees\":[{\"Employee_id\":\"1\",\"Employee_name\":\"Sravan\",\"status\":\"1\"},]}}}";

and if you have any other question , I will be happy to help you :)

Answer 2

Try your JSON with http://json2csharp.com/ . Your current code would deserialize the following JSON:

{  
   "status":"fail",
   "content":{  
      "user_id":"56",
      "first":"kiran",
      "last":"kumar",
      "username":"kirankumar"
   },
   "msg":"shggh"
}

You are missing a root class with a single Property "response" with the type "Response"
