Conversion between json and object

      public static string ObjToJson<T>(T obj)
      {
         DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
         string retVal = Constant.strNullString;
         using (MemoryStream ms = new MemoryStream())
         {
            serializer.WriteObject(ms, obj);
            retVal = Encoding.UTF8.GetString(ms.ToArray());
         }
         return retVal;
      }

      public static T JsonToObj<T>(string json)
      {
         T obj;
         using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
         {
            DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T));
            obj = (T)serializer.ReadObject(ms);
         }
         return obj;
      }

Object should be defined as follows (add attributes "[DataContract]" and "[DataMember]" ): 

 

   [DataContract]
   public class MyObject
   {
      [DataMember]
      public int Member1{ get; set; }
      [DataMember]
      public string Member2 { get; set; }
   }
