Intercommunication Process Using TCP

//Here is the method to send some strings through a port

// Create a new instance of TCPListener and indicate the port
TcpListener l = new TcpListener(1001);
// Start Listener
l.Start();
// wait for client to make request
TcpClient c = l.AcceptTcpClient(); 
// access steam to send data to client.
NetworkStream ns = c.GetStream(); 
// get system date and convert it to string
string st = txtSend.Text; 
//convert string to an array of Bytes
byte[] buf = System.Text.Encoding.ASCII.GetBytes(st); 
//write to stream
ns.Write(buf, 0, st.Length);
// Stop Listener
l.Stop();

//Here is the method to Receive some strings through a port

// Create a new instance of TCPClient and indicate the port
TcpClient c = new TcpClient("localhost", 1001);
// get stream
NetworkStream ns = c.GetStream(); 
// create byte array to receive data
byte[] buf = new byte[100];  
//read data from stream into byte array
ns.Read(buf, 0, 100);// convert byte array to stringstring st = System.Text.Encoding.ASCII.GetString(buf);
