create a simple TCP based console chat room using C Any help

create a simple TCP based console chat room using C#. Any help would be really appreciated.

Your Program must compile This program should be done in C# In this assignment I want you to create a TCP based console chat room. The idea is fairly simple - accept multiple clients on a given TCP port (say 245) and whenever someone sends a string with new line relay it to the other clients. The server should ask the client for a name on first connect, and if one isn\'t provided to automatically generate one (a simple name generating algorithm could be to take the MD5, SHA1 or base64 of the current Unix date time stamp and only use the first N characters as the username). In terms of design you should have at least class for the client, \"chatroom\", and server. Here is an example:

Solution

using System;

using System.Threading;

using System.Net.Sockets;

using System.Text;

using System.Collections;

namespace ConsoleApplication1

{

    class Program

    {

        public static Hashtable clientsList = new Hashtable();

        static void Main(string[] args)

        {

            TcpListener serverSocket = new TcpListener(245);

            TcpClient clientSocket = default(TcpClient);

            int counter = 0;

            serverSocket.Start();

            Console.WriteLine (\"Chat Server Started ....\");

            counter = 0;

            while ((true))

            {

                counter += 1;

                clientSocket = serverSocket.AcceptTcpClient();

                byte[] bytesFrom = new byte[1002];

                string dataFromClient = null;

                NetworkStream networkStream = clientSocket.GetStream();

                networkStream.Read(bytesFrom, 0, (int)clientSocket.ReceiveBufferSize);

                dataFromClient = System.Text.Encoding.ASCII.GetString(bytesFrom);

                dataFromClient = dataFromClient.Substring(0, dataFromClient.IndexOf(\"$\"));

                clientsList.Add(dataFromClient, clientSocket);

                broadcast(dataFromClient + \" Joined \", dataFromClient, false);

                Console.WriteLine(dataFromClient + \" Joined chat room \");

                handleClinet client = new handleClinet();

                client.startClient(clientSocket, dataFromClient, clientsList);

            }

            clientSocket.Close();

            serverSocket.Stop();

            Console.WriteLine(\"exit\");

            Console.ReadLine();

        }

        public static void broadcast(string msg, string uName, bool flag)

        {

            foreach (DictionaryEntry Item in clientsList)

            {

                TcpClient broadcastSocket;

                broadcastSocket = (TcpClient)Item.Value;

                NetworkStream broadcastStream = broadcastSocket.GetStream();

                Byte[] broadcastBytes = null;

                if (flag == true)

                {

                    broadcastBytes = Encoding.ASCII.GetBytes(uName + \" says : \" + msg);

                }

                else

                {

                   broadcastBytes = Encoding.ASCII.GetBytes(msg);

                }

                broadcastStream.Write(broadcastBytes, 0, broadcastBytes.Length);

                broadcastStream.Flush();

            }

        }

    }

    public class handleClinet

    {

        TcpClient clientSocket;

        string clNo;

        Hashtable clientsList;

        public void startClient(TcpClient inClientSocket, string clineNo, Hashtable cList)

        {

            this.clientSocket = inClientSocket;

            this.clNo = clineNo;

            this.clientsList = cList;

            Thread ctThread = new Thread(doChat);

            ctThread.Start();

        }

        private void doChat()

        {

            int requestCount = 0;

            byte[] bytesFrom = new byte[10025];

            string dataFromClient = null;

            Byte[] sendBytes = null;

            string serverResponse = null;

            string rCount = null;

            requestCount = 0;

            while ((true))

            {

                try

                {

                    requestCount = requestCount + 1;

                    NetworkStream networkStream = clientSocket.GetStream();

                    networkStream.Read(bytesFrom, 0, (int)clientSocket.ReceiveBufferSize);

                    dataFromClient = System.Text.Encoding.ASCII.GetString(bytesFrom);

                    dataFromClient = dataFromClient.Substring(0, dataFromClient.IndexOf(\"$\"));

                    Console.WriteLine(\"From client - \" + clNo + \" : \" + dataFromClient);

                    rCount = Convert.ToString(requestCount);

                    Program.broadcast (dataFromClient, clNo, true);

                }

                catch (Exception ex)

                {

                    Console.WriteLine(ex.ToString());

                }
