JSON parsing in windows phone 8 - json

Question

i am new to windows phone development and so by references implemented some code but i am not able to get the desired result.
i want to parse a JSON that is received as a response from the server.
Please find below my code.
class JSONParsing
{
public Status response { get; set; }
public static void webClient1_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
if (!String.IsNullOrEmpty(e.Result))
{
try
{
JSONParsing root = JsonConvert.DeserializeObject<JSONParsing>(e.Result);
// root is null here
JObject obj = root.response.statusDetail;
// from here it goes to Catch block
foreach (KeyValuePair<string, JToken> pair in obj)
{
string key = pair.Key;
foreach (JObject detail in pair.Value as JArray)
{
string Code = detail["Code"].ToString();
string Msg = detail["Msg"].ToString();
string RegistrationID = detail["RegistrationID"].ToString();
string Name = detail["Name"].ToString();
string Phone = detail["Phone"].ToString();
string email = detail["email"].ToString();
string password = detail["password"].ToString();
}
}
}
catch (Exception ex)
{
Console.WriteLine("Cause of Exception is " + ex.Message);
// exception is-- "Object reference not set to an instance of an object."
}
} // if for empty
}
}
public class Status
{
public string Code { get; set; }
public string Msg { get; set; }
public object RegistrationID { get; set; }
public string Name { get; set; }
public string Phone { get; set; }
public string email { get; set; }
public string password { get; set; }
[JsonProperty("")]
public JObject statusDetail { get; set; }
}
public class RootObject
{
public List<Status> Status { get; set; }
public int success { get; set; }
}
}
Please Help.

If root is null the class 'JSONParsing' is not having same class structure as the json
and since root is null, accessing property inside a null('root.response.statusDetail') will throw an exception
you can use http://json2csharp.com/ to get the class structure of the json
