来自 GCM 的响应是什么意思，为什么通知不起作用

我有一些将通知c#推送到GCM的代码。当我运行代码 c# 时，GCM 会像这样回复我一个 id：id=0：145310308361%a68blablad6cf16 。但是状态代码：确定。这个id和另一个问题是什么意思：推送通知功能中的此响应，但是当我运行此功能时，我的设备不接受通知？

C# 代码如下所示：

 public string SendAndroidPushNotification(string RegistrationID, string message)
{
    string GoogleAppID = "ServerId";
    var SENDER_ID = "ProjectId";
    var value = message;
    WebRequest tRequest;
    tRequest = WebRequest.Create("https://android.googleapis.com/gcm/send");
    tRequest.Method = "post";
    tRequest.ContentType = " application/x-www-form-urlencoded;charset=UTF-8";
    tRequest.Headers.Add(string.Format("Authorization: key={0}", GoogleAppID));
    tRequest.Headers.Add(string.Format("Sender: id={0}", SENDER_ID));
    string postData = "collapse_key=score_update&time_to_live=108&delay_while_idle=1&data.message=" + value.ToString() + "&data.time=" + System.DateTime.Now.ToString() + "&registration_id=" + RegistrationID + "";
    //Console.WriteLine(postData);
    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();
    HttpWebResponse httpResponse = (HttpWebResponse)tResponse;
    string statusCode = httpResponse.StatusCode.ToString();
    tReader.Close();
    dataStream.Close();
    tResponse.Close();
    return sResponseFromServer;
}
protected void Button1_Click(object sender, EventArgs e)
{
    string device_Id = "myRegisteredId";
    string msj = "";
    msj = TextBox1.Text.ToString();
    string strResponse = SendAndroidPushNotification(device_Id, msj);
}
