Odeslani XML pres TCP/IP

C# .NET

public void HandleClient(object tcpClient) {

  TcpClient client = (TcpClient) tcpClient;
  var stream = client.GetStream();

  string data = null;
  byte[] bytes = new Byte[2560];

  while ((i = stream.Read(bytes, 0, bytes.Length)) != 0) {

    var serializer = new XmlSerializer(typeof (AlarmMessage));

    using(TextReader reader = new StringReader(data)) {
      var result = (AlarmMessage)serializer.Deserialize(reader);

      if (result != null) {
        
        // ulozeni dat z result

        // ZDE ODESILAM POTVRZENI KLIENTOVI
        byte[] reply = ConfirmReceive(result.Ref);
        stream.Write(reply, 0, reply.Length);

        client.Close();

      }
    }

    if (!client.Connected)
      break;

  }

}

// vytvori xml odpoved ve formatu <ack ref="refId" />
