hi one and all... the below given code enables to listen from localhost but i was wondering if we could send message back to localhost/browser.. any help how to send message for example like This is test

using System;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Text;

class MyTcpListener
public static void Main()


// Set the TcpListener on port 13000.
Int32 port = 80;
IPAddress localAddr = IPAddress.Parse("");

// TcpListener server = new TcpListener(port);
TcpListener server = new TcpListener(localAddr, port);

// Start listening for client requests.

// Buffer for reading data
Byte[] bytes = new Byte[256];
String data = null;

// Enter the listening loop.
while (true)
Console.Write("Waiting for a connection... ");

// Perform a blocking call to accept requests.
// You could also user server.AcceptSocket() here.
TcpClient client = server.AcceptTcpClient();

data = null;

// Get a stream object for reading and writing
NetworkStream stream = client.GetStream();

int i;

// Loop to receive all the data sent by the client.
while ((i = stream.Read(bytes, 0, bytes.Length)) != 0)
// Translate data bytes to a ASCII string.
data = System.Text.Encoding.ASCII.GetString(bytes, 0, i);
Console.WriteLine(String.Format("Received: {0}", data));

// Process the data sent by the client.
data = data.ToUpper();

byte[] msg = System.Text.Encoding.ASCII.GetBytes(data);

// Send back a response.
stream.Write(msg, 0, msg.Length);
Console.WriteLine("Sending message..");


// Shutdown and end connection
catch (SocketException e)
Console.WriteLine("SocketException: {0}", e);

Console.WriteLine("\nHit enter to continue...");

your basic problem is, what is going to listen to your message, and how do you expect it to respond ? Your best way to send something to a web server, is to host a web service on it. You CAN do a HTTPPost, and you could try to make it look like a returning post from a web page, but again, if you have full control over the server, a web service is the logical choice.
