HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://Server:8000/sap/opu/odata/sap/ZCUST_TESTING_SRV/post_cust");

//byte[] byteArray = Encoding.UTF8.GetBytes(postXml);

byte[] byteArray = Encoding.ASCII.GetBytes(jsonnew);

request.Credentials = new NetworkCredential("mobtest","welcome1");

request.ContentType = "application/atom+xml";

request.Method = "GET";

//request.Headers["Authorization"] = "Basic " + System.Convert.ToBase64String(auth);

request.Headers["X-CSRF-Token"] = "Fetch";

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

xToken = responseH.Headers["X-CSRF-Token"];

Console.WriteLine("xToken : " + xToken.ToString());

responseH.Close();

Stream dataStream1 = request_post.GetRequestStream();

dataStream1.Write(byteArray, 0, byteArray.Length);

Console.WriteLine("byteArray : "+byteArray);

dataStream1.Close();

Console.WriteLine("datastream1");

HttpWebResponse response1 = (HttpWebResponse)request.GetResponse();

Console.WriteLine("Post response : " + response1.ToString());

dataStream1 = response1.GetResponseStream();

StreamReader reader1 = new StreamReader(dataStream1);

Console.WriteLine(" Console.WriteLine(reader1 : " + reader1);

string responseFromServer1 = reader1.ReadToEnd();

Console.WriteLine(" Console.WriteLine(responseFromServer1 : " + responseFromServer1);
