Manual Serializaion / Deserialization of Datacontract classes

In the example given below, we will first serialize an object in memory and then deserializeit.

MemoryStream mStream = new MemoryStream();


-- Seriailize an Object

public  void WriteObject(ClassTest objTest)
         {
           
             DataContractSerializer ser =
                 new DataContractSerializer(typeof(ClassTest ));
             ser.WriteObject(mStream, objTest);
            
         }

-- Deserialize the object in memory

 public void ReadObject(ClassTest objTest)
         {
            
             DataContractSerializer ser = new DataContractSerializer(typeof(ClassTest ));

            string result = Encoding.UTF8.GetString(mStream.GetBuffer(), 0, (int)mStream.Position);
             MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(result));

             EntityObj deserializedObj =
                 (EntityObj)ser.ReadObject(ms);
             mStream.Close();
            
         }
