Below is my code.. tiwari-mike public void SendMessageiOS(string deviceID, string message) { int port = 2195; String hostname = 'gateway.push.apple.com'; //C:\Windows\System32\inetsrv //load certificate string certificatePath = System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, 'Loyalty_Prod_Certi.p12'); string certificatePassword = '1234'; // string certificatePath = System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, '_DistriCertificates.p12'); // X509Certificate2 clientCertificate = new X509Certificate2(System.IO.File.ReadAllBytes(certificatePath), '1234'); X509Certificate2 clientCertificate = new X509Certificate2(certificatePath); X509Certificate2Collection certificatesCollection = new X509Certificate2Collection(clientCertificate); TcpClient client = new TcpClient(hostname, port); SslStream sslStream = new SslStream( client.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null ); try { sslStream.AuthenticateAsClient(hostname, certificatesCollection, SslProtocols.Tls, true); } catch (Exception ex) { client.Close(); return; } 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) //byte[] AppID = Encoding.UTF8.GetBytes(deviceID.ToUpper()); writer.Write(StringToByteArrayFastest(deviceID.ToUpper())); //writer.Write(AppID); String payload = '{\'aps\':{\'alert\':\'Message\',\'badge\':0,\'sound\':\'default\'}}'; payload = payload.Replace(' Message ', message); 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(); client.Close(); }

Hi, I have used the below code, public class PushNotification { // private static readonly Logger Logger = LogManager.GetCurrentClassLogger(); private TcpClient _apnsClient; private SslStream _apnsSSLStream; private X509Certificate2 _clientCertificate; private X509CertificateCollection _certificatesCollection; private bool _conected = false ; private Dictionary int , string> _errorList = new Dictionary int , string>(); private List _rejected = new List (); // private List _loglist = new List (); public void PushMessage(List DeviceTokens, string Messagetext, byte[] Certificate, string Certificatepassword, string HostName, int Port) { try { // Loading Apple error response list. _errorList.Add(0, "No errors encountered" ); _errorList.Add(1, "Processing error" ); _errorList.Add(2, "Missing device token" ); _errorList.Add(3, "Missing topic" ); _errorList.Add(4, "Missing payload" ); _errorList.Add(5, "Invalid token size" ); _errorList.Add(6, "Invalid topic size" ); _errorList.Add(7, "Invalid payload size" ); _errorList.Add(8, "Invalid token" ); _errorList.Add(255, "None (unknown)" ); Messagetext = Messagetext.Replace( "
