Question

I am attempting to write text out to a text file:

        byte[] b = new byte[100];
        int k = s.Receive(b);
        Console.WriteLine("Recieved...");
        for (int i = 0; i < k; i++)
        {
            Console.Write(Convert.ToChar(b[i]));
            //TextWriter tw = new StreamWriter("output.txt");
            //tw.WriteLine(Convert.ToChar(b[i]));

        }

Although the Console.Write method works perfectly, and text output is displayed on screen, but when I use the TextWriter method the application produces 100’s of errors (continues) and does not output anything to the output file specified

Is there any other way of getting the output of “Console.Write(Convert.ToChar(b[i]));” to a text file?

Below is a sample of the errors:

The full code follows:

  try
    {

        IPAddress ipAd = IPAddress.Parse("172.16.0.37"); //use local m/c IP address, and use the same in the client

        /* Initializes the Listener */
        TcpListener myList = new TcpListener(ipAd, 8111);

        /* Start Listeneting at the specified port */
        myList.Start();


            Console.WriteLine("The server is running at port 8111...");
            Console.WriteLine("The local End point is  :" + myList.LocalEndpoint);
            Console.WriteLine("Waiting for a connection.....");


        Socket s = myList.AcceptSocket();
        Console.WriteLine("Connection accepted from " + s.RemoteEndPoint);

        byte[] b = new byte[100];
        int k = s.Receive(b);
        Console.WriteLine("Recieved...");
        using (var txt = File.OpenWrite("output.txt"))
        {
            for (int i = 0; i < k; i++)
            {
                Console.Write(Convert.ToChar(b[i]));
                txt.WriteLine(Convert.ToChar(b[i]));
            }
        }




        ASCIIEncoding asen = new ASCIIEncoding();
        s.Send(asen.GetBytes("The string was recieved by the server."));
        Console.WriteLine("\nSent Acknowledgement to Client");
        /* clean up */
        s.Close();
        myList.Stop();


    }
    catch (Exception e)
    {
        Console.WriteLine("Error..... " + e.StackTrace);
    }
    // Loop the process
    loop();
}

Maybe this is what you’re trying to do?

byte[] b = new byte[100];
int k = s.Receive(b);
Console.WriteLine("Recieved...");
using (var sw = new StreamWriter("output.txt"))
{
    for (int i = 0; i < k; i++)
    {
        Console.Write(Convert.ToChar(b[i]));
        sw.Write(Convert.ToChar(b[i]));
    }
}
