here is the code in c#

        tRequest = WebRequest.Create("https://android.googleapis.com/gcm/send");
        tRequest.Method = "post";
        tRequest.ContentType = "application/x-www-form-urlencoded";
        tRequest.Headers.Add(string.Format("Authorization: key={0}", GoogleAppID));
String collaspeKey = Guid.NewGuid().ToString("n");
String postData=string.Format("registration_id={0}&data.payload={1}&collapse_key={2}", DeviceID, "Pickup Message" + DateTime.Now.ToString(), collaspeKey);
Byte[] byteArray = Encoding.UTF8.GetBytes(postData);
tRequest.ContentLength = byteArray.Length;

Stream dataStream = tRequest.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();

WebResponse tResponse = tRequest.GetResponse();

dataStream = tResponse.GetResponseStream();

StreamReader tReader = new StreamReader(dataStream);

String sResponseFromServer = tReader.ReadToEnd();

tReader.Close();
dataStream.Close();
tResponse.Close();
