Merci

Salut,

Se connecter avec les asp.net a du tcp? Ca veut dire quoi exactement? Tu as TcpClient mais faudrait que tu donnes plus de détails.

Je veux recuperer des datas qui se trouvent sur un server dont le protocole est du tcp.

Le meme code fonctionne en application Console mais impossible avec les asp.net :

public string SetServerConnection()
        {
            try
            {
                server = new TcpClient("00.00.00.00", 1000);
                networkStream = server.GetStream();

 public string SetLogin()
        {
            try
            {
                if (server.Connected)
                {
                    input = "Command de login - pwd";
 
                    ASCIIEncoding aSCIIEncoding = new ASCIIEncoding();
                    byte[] message = aSCIIEncoding.GetBytes(input);
 
                    networkStream.Write(message, 0, message.Length);
                    byte[] bb = new byte[256];
 
                    int k = networkStream.Read(bb, 0, bb.Length);
 
                    for (int i = 0; i < k; i++)
                    {
                        if (bb[i] != 16 && bb[i] != 17)
                        {
                            result += Convert.ToChar(bb[i]);
                        }
                    }
 
                    return result;
                }
                return "You are not connected";
            }
            catch (Exception e)
            {
                return e.Message;
            }
        }

J'ai l'impression que je recupere uniquement que le stream de la SetServerConnection et non de SetLogin.


Je comprends plus rien !!!!
