            {
                sslStream.AuthenticateAsClient(hostname, certificatesCollection, SslProtocols.Ssl3, false);
                MemoryStream memoryStream = new MemoryStream();
                BinaryWriter writer = new BinaryWriter(memoryStream);
                writer.Write((byte)0);  //The command
                writer.Write((byte)0);  //The first byte of the deviceId length (big-endian first byte)
                writer.Write((byte)32); //The deviceId length (big-endian second byte)
                writer.Write(HexStringToByteArray(deviceID.ToUpper()));
                String payload = "{'"aps'":{'"alert'":'"" + Mesaj + "'",'"badge'":1,'"sound'":'"default'"}}";
                writer.Write((byte)0);
                writer.Write((byte)payload.Length);
                byte[] b1 = System.Text.Encoding.UTF8.GetBytes(payload);
                writer.Write(b1);
                writer.Flush();
                byte[] array = memoryStream.ToArray();
                sslStream.Write(array);
                sslStream.Flush();

                lblResponse.Text = "Sucess..";
            }
            catch (System.Security.Authentication.AuthenticationException ex)
            {
                client.Close();
                lblResponse.Text = ex.Message;
            }   
            catch (Exception e)
            {
                client.Close();
                lblResponse.Text = e.Message;
            }
        }
        // The following method is invoked by the RemoteCertificateValidationDelegate. 
        public static bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
        {
            if (sslPolicyErrors == SslPolicyErrors.None)
                return true;
            else // Do not allow this client to communicate with unauthenticated servers. 
                return false;
        }
        private static byte[] HexStringToByteArray(String DeviceID)
        {
            //convert Devide token to HEX value.
            byte[] deviceToken = new byte[DeviceID.Length / 2];
            for (int i = 0; i < deviceToken.Length; i++)
                deviceToken[i] = byte.Parse(DeviceID.Substring(i * 2, 2), System.Globalization.NumberStyles.HexNumber);
            return deviceToken;
        }
    }
}

以上是我发送通知的后端源代码。我的代码调试成功并获得消息。但是我无法在iPhone上获得通知。

我遵循这个http://blog.serverdensity.com/how-to-build-an-apple-push-notification-provider-server-tutorial/。我不知道问题出在哪里。你能帮我解决这个问题吗?

通过本教程，它解释了从开始到结束所需的一切，并且工作完美。它解释了如何设置服务器端和ios设备上的所有内容，以及如何在开发人员门户中整理所有证书。
