Simple Communication between two WPF Application in same PC

I have created a simple communication between two WPF windows application, by which you can send any number of data as string. Right now i am closing TCP Connection just after successful result. You can do this multiple time.

So Here is the code

Client Side Code: (Sender)
        //Publish this location to other opend application
     void sendData(string data)
     {
            try
            {
                TcpClient tcpclnt = new TcpClient();
                tcpclnt.Connect("127.0.0.1", 8001);
                // use the ipaddress as in the server program

                String str = data;
                Stream stm = tcpclnt.GetStream();

                ASCIIEncoding asen = new ASCIIEncoding();
                byte[] ba = asen.GetBytes(str);
                
                stm.Write(ba, 0, ba.Length);
                tcpclnt.Close();
            }

            catch (Exception em)
            {
                Console.WriteLine("Error..... " + em.StackTrace);
            }
     }


Server Side Code: (Receiver)
       //To Listen the Connection type code for an event, As i write here for a button
     private void Button_Click(object sender, RoutedEventArgs e)
     {
            try
            {
                IPAddress ipAd = IPAddress.Parse("127.0.0.1");
                TcpListener myList = new TcpListener(ipAd, 8001);
                myList.Start();

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

                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]));

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

            }
            catch (Exception em)
            {
                Console.WriteLine("Error..... " + em.StackTrace);
            }

     }
