        TcpClient client = new TcpClient("127.0.0.1", 4554);
        try
        {
            Stream s = client.GetStream();
            StreamReader sr = new StreamReader(s);
            StreamWriter sw = new StreamWriter(s);
            sw.AutoFlush = true;
 // Create an instance of StreamReader to read from a file.
            // The using statement also closes the StreamReader.
            StreamReader srt = new StreamReader("trame.txt");
            String line;
 // Read and display lines from the file until the end of 
           // the file is reached.
 
 
            while ((line = srt.ReadLine()) != null)
            {
                sw.WriteLine(line);
 
            }
            s.Close();
        }
        finally
        {
            // code in finally block is guranteed 
 
            // to execute irrespective of 
 
            // whether any exception occurs or does 
 
            // not occur in the try block
 
             client.Close();

Tu as mis 2 fois le code du client, il n'y a pas celui du serveur...

Sinon il manque un client.Connect avant le client.GetStream
