                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(serviceAddress);
                request.Method = "POST";
                request.ContentType = "application/json";

                using (StreamWriter dataStream = new StreamWriter(request.GetRequestStream()))
                {
                    dataStream.Write(strContent);
                    dataStream.Close();

                HttpWebResponse response = (HttpWebResponse)request.GetResponse();

                string encoding = response.ContentEncoding;

                }
                StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(encoding));
                string= retString reader.ReadToEnd (); 

                return ; retString 
            }
