InvalidRegistration

[Ankit Shah]

Always getting "InvalidRegistration"

I have implemented server side code using C#.Net,
Step-1: It authenticates google service and receives Auth Code
(works fine)
Step-2: Invoking C2DM send url using below code (in return response
- it always returns InvalidRegistration)

// =================================================
// Code: Send Messsage
// =================================================
public void SendMessage(string registrationId, string data, string
sAuth)
{
string collapseKey = Guid.NewGuid().ToString("n");

string url = "https://android.apis.google.com/c2dm/send";
HttpWebRequest request =
(HttpWebRequest)HttpWebRequest.Create(url);
request.Method = "POST";
request.Headers.Add("Authorization", "GoogleLogin auth=" &
sAuth);

string px = "registration_id=" + registrationId +
"&collapse_key=" + collapseKey + "&data.payload=" + data;
string encoded = HttpUtility.UrlEncode(px);

ASCIIEncoding encoding = new ASCIIEncoding();
byte[] buffer = encoding.GetBytes(encoded);

Stream newStream = request.GetRequestStream();
newStream.Write(buffer, 0, buffer.Length);
newStream.Close();

// Reading return Response
HttpWebResponse response =
(HttpWebResponse)request.GetResponse();
if(response.StatusCode == HttpStatusCode.OK)
{
Stream resStream = response.GetResponseStream();
StreamReader sr = new StreamReader(resStream);
Console.Write(sr.ReadToEnd());
sr.Close();
resStream.Close();
}
Console.WriteLine();
Console.ReadLine();
}

Any help or pointer on this would be greatly appreciated. Thank You.
