Como dice el título, tengo un problema con UDP en C #. Estoy tratando de construir una biblioteca para el protocolo rcon del juego DayZ.

Mi problema es que no recibo todos los paquetes que debo recibir. Después de enviar un comando, el servidor responde con una respuesta dividida. El encabezado del paquete contiene el recuento total de paquetes y el índice del paquete actual. Ahora, si obtengo 17 paquetes, solo obtengo 8-15 paquetes en mi aplicación.

Después de realizar pruebas con WireShark, ahora sé que todos los paquetes llegan a mi computadora. Simplemente no son reconocidos por mi aplicación o algo así.

Mi pregunta real es: ¿Es posible evitar perder los paquetes entre mi tarjeta de red y mi aplicación? o ¿Por qué sucede eso?

Aquí está mi código actual. Está bastante sucio porque lo destrozé después de no funcionar como se esperaba:

    private Socket _udpClient;
    private Thread _receiverThread;
    private Thread _workerThread;
    private Queue<byte[]> _packetQueue;
    private PacketBuffer[] MessageBuffer;
    private byte SenderSequence = 0;
    private IPEndPoint connection;

    public RCon(IPAddress ip, int port)
    {
        connection = new IPEndPoint(ip, port);
        _udpClient = new Socket(connection.Address.AddressFamily, SocketType.Dgram, ProtocolType.Udp);
        _udpClient.Connect(connection);
        MessageBuffer = new PacketBuffer[256];
        _packetQueue = new Queue<byte[]>();

        _receiverThread = new Thread(new ThreadStart(ReceiveCallback));
        _receiverThread.IsBackground = true;
        _receiverThread.Priority = ThreadPriority.AboveNormal;
        _receiverThread.Start();
        _workerThread = new Thread(new ThreadStart(WorkerCallback));
        _workerThread.IsBackground = true;
        _workerThread.Start();
    }

    public void Login(string password)
    {
        LoginPacket packet = new LoginPacket(password);

        _udpClient.Send(packet.Bytes);
    }

    public void SendCommand(string command)
    {
        CommandPacket packet = new CommandPacket(SenderSequence, command);
        SenderSequence++;

        _udpClient.Send(packet.Bytes);
    }

    private void ReceiveCallback()
    {

        while (true)
        {
                byte[] buffer = new byte[1036];
                if (_udpClient.Receive(buffer) > 0)
                    _packetQueue.Enqueue(buffer);
        }
    }

    private void WorkerCallback()
    {
        while (true)
        {
            if (_packetQueue.Count > 0)
            {
                byte[] buffer = _packetQueue.Dequeue();

                if (buffer != null)
                {
                    try
                    {
                        Packet receivedPacket = Packet.ParseIncoming(buffer);

                        OnPacketReceived(new PacketReceivedEventArgs(receivedPacket));

                        switch (receivedPacket.Type)
                        {
                            case PacketType.Message:
                                OnMessageReceived(new MessageReceivedEventArgs(receivedPacket.Content));
                                MessageCallbackPacket packet = new MessageCallbackPacket(receivedPacket.SequenceNumber);
                                _udpClient.Send(packet.Bytes);
                                break;
                            case PacketType.CommandCallback:
                                if (MessageBuffer[receivedPacket.SequenceNumber] == null)
                                    MessageBuffer[receivedPacket.SequenceNumber] = new PacketBuffer(receivedPacket);
                                else
                                    MessageBuffer[receivedPacket.SequenceNumber].AddPacket(receivedPacket);

                                if (MessageBuffer[receivedPacket.SequenceNumber].IsComplete)
                                    OnCommandCallback(new CommandCallbackEventArgs(MessageBuffer[receivedPacket.SequenceNumber].GetContent()));
                                break;
                        }
                    }
                    catch (ArgumentException) { }
                    catch (OverflowException) { }
                    catch (FormatException) { }
                }
            }
        }
    }
