How to test TcpListener for localhost and port number in c#

Question

I have a code in c# which reads the data from tcp ipaddress and port number but my problem is this that i dont have any testing plateform with ipaddress and port number to test the application.My concern is this that is there any way by which i can test my code in local environmnet..

Here is my code..

 public class Listener
{

    private TcpListener tcpListener;
    private Thread listenThread;
    // Set the TcpListener on port 8081.
    Int32 port = 8081;
    IPAddress localAddr = IPAddress.Parse("192.168.1.3");
    Byte[] bytes = new Byte[256];

    public void ListenForClients()
    {

        this.tcpListener.Start();

        while (true)
        {
            //blocks until a client has connected to the server
            TcpClient client = this.tcpListener.AcceptTcpClient();

            //create a thread to handle communication 
            //with connected client
            Thread clientThread = new Thread(new ParameterizedThreadStart(HandleClientComm));
            clientThread.Start(client);
        }
    }
    public void HandleClientComm(object client)
    {
        TcpClient tcpClient = (TcpClient)client;
        NetworkStream clientStream = tcpClient.GetStream();

        byte[] message = new byte[4096];
        int bytesRead;

        while (true)
        {
            bytesRead = 0;

            try
            {
                //blocks until a client sends a message
                bytesRead = clientStream.Read(message, 0, 4096);
            }
            catch
            {
                //a socket error has occured
                // System.Windows.MessageBox.Show("socket");
                break;
            }

            if (bytesRead == 0)
            {
                //the client has disconnected from the server
                // System.Windows.MessageBox.Show("disc");
                break;
            }

            //message has successfully been received
            ASCIIEncoding encoder = new ASCIIEncoding();

            String textdata = encoder.GetString(message, 0, bytesRead);
            System.IO.File.AppendAllText(@"D:\ipdata.txt", textdata);


        }

        tcpClient.Close();
    }
}

Please help me to solve this .. Thanks in advance..

Answer 1

To test the TCP listening application, you obviously need to write TCP transferring one. You can write it and:

• Run them simultaneously

OR

• Run listener on your OS and transmitter in virtual machine. I made so and has written a post on my blog on Russian (sources are also available for download).

Answer 2

I think you can configure the listener to 127.0.0.1 and test logic via localhost connetcion if you have transmitting part of system

Answer 3

Use RESTClient chrome/firefox AddOn (http://restclient.net/) to send data to IP and Port in Intranet environment, I use this
