Stream os = null;
try
{ // Send the Post Data 
    webRequest.ContentLength = bytes.Length;   
    os = webRequest.GetRequestStream();
    os.Write(bytes, 0, bytes.Length);    

    Console.WriteLine(String.Format(@"{0}", byteString));     // <- This matches the Json object
}
catch (WebException ex)
{ //Handle Error }

try
{ // Get the response
    WebResponse webResponse = …
