Converting Normal Parameter Values to JSON Parameter values and Vice Versa

From normal values to Json Parameters:

using (MemoryStream ms = new MemoryStream())

{

DataContractJsonSerializer serializer = new DataContractJsonSerializer(objuser1.GetType());

serializer.WriteObject(ms, objuser1);
ms.Position = 0;
using (StreamReader reader = new StreamReader(ms))
{
string JsonString= reader.ReadToEnd();
Label11.Text = JsonString;
}
}

From Json parameters to normal parameters:

string url = Server.MapPath("~/App_Data/JsonResult.txt");

System.IO.StreamReader myFile = new System.IO.StreamReader(url);
string myString = myFile.ReadToEnd();
myFile.Close();
Stream stream = new MemoryStream(Encoding.Unicode.GetBytes(myString.ToString()));
User1 objuser = new User1();

DataContractJsonSerializer objSerializer = new DataContractJsonSerializer(typeof(User1));

objuser = (User1)objSerializer.ReadObject(stream);

public class User1

{
public string UserName { get; set; }
public string FOUnit { get; set; }
public string CashLimit { get; set; }
public string TotalCollected { get; set; }
public string TotalRemitted { get; set; }

}
