Non autorisée lors de l'appel de Google GCM

Que j'essaie d'utiliser Google GCM pour l'envoi de notifications push. Mais obtenir un WebException qui dit que le serveur distant renvoie 401 interventions non autorisées. Je ne peux pas foung pourquoi il ne débite pas de travail.

Quelqu'un qui sait pourquoi ça ne marche pas?

Voici mon code:

            ServicePointManager.ServerCertificateValidationCallback += new RemoteCertificateValidationCallback(ValidateServerCertificate);

           HttpWebRequest Request = (HttpWebRequest)WebRequest.Create("https://android.googleapis.com/gcm/send");


            Request.Method = "POST";
            Request.KeepAlive = false;

            string postData = "{ 'registration_ids': [ '"+registrationId+"' ], 'data': {'message': '"+message+"'}}";

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

            Request.ContentType = "application/json";
            //Request.ContentLength = byteArray.Length;


            //Request.Headers.Add(HttpRequestHeader.Authorization, "GoogleLogin auth=" + AuthString);
            Request.Headers.Add(HttpRequestHeader.Authorization, "Authorization: key=AIzaSyCEygavdzrNM3pWNPtvaJXpvW66CKnjH_Y");
            //-- Delegate Modeling to Validate Server Certificate --//


            //-- Create Stream to Write Byte Array --//
            Stream dataStream = Request.GetRequestStream();
            dataStream.Write(byteArray, 0, byteArray.Length);
            dataStream.Close();

            //-- Post a Message --//
            WebResponse Response = Request.GetResponse();
            HttpStatusCode ResponseCode = ((HttpWebResponse)Response).StatusCode;
            if (ResponseCode.Equals(HttpStatusCode.Unauthorized) || ResponseCode.Equals(HttpStatusCode.Forbidden))
            {
                var text = "Unauthorized - need new token";

            }
            else if (!ResponseCode.Equals(HttpStatusCode.OK))
            {
                var text =  "Response from web service isn't OK";
            }

            StreamReader Reader = new StreamReader(Response.GetResponseStream());
            string responseLine = Reader.ReadLine();
            Reader.Close();
