Hello everyone,

I need alot of help from anyone of you. As i am totally suck with programming, and i was given a project to do on server - client system using C#.

I was able to get some information on 1 server to 1 client programming. but i need to write a program on 1 server to many clients.. I think it is called MultiThreads.

Hope someone can guide me through and help me up with some sample or links for my reference..

Thanks..

What do you have so far.
Any outline ?
Do you know how to start new threads ?
Do you know how to have one client talk to one server ?

Hi Protector,

Oh ya, i totally duno about anything, i got the sample code on this some link..

/* Server Program */

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

public class serv {
public static void Main() {
try {
IPAddress ipAd = IPAddress.Parse("172.21.5.99");
// use local m/c IP address, and
// use the same in the client

/* Initializes the Listener */
TcpListener myList=new TcpListener(ipAd,8001);

/* Start Listeneting at the specified port */
myList.Start();

Console.WriteLine("The server is running at port 8001...");
Console.WriteLine("The local End point is :" +
myList.LocalEndpoint );
Console.WriteLine("Waiting for a connection.....");

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 e) {
Console.WriteLine("Error..... " + e.StackTrace);
}
}

}

--------------------------------------------------

/* Client Program */

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


public class clnt {

public static void Main() {

try {
TcpClient tcpclnt = new TcpClient();
Console.WriteLine("Connecting.....");

tcpclnt.Connect("172.21.5.99",8001);
// use the ipaddress as in the server program

Console.WriteLine("Connected");
Console.Write("Enter the string to be transmitted : ");

String str=Console.ReadLine();
Stream stm = tcpclnt.GetStream();

ASCIIEncoding asen= new ASCIIEncoding();
byte[] ba=asen.GetBytes(str);
Console.WriteLine("Transmitting.....");

stm.Write(ba,0,ba.Length);

byte[] bb=new byte[100];
int k=stm.Read(bb,0,100);

for (int i=0;i<k;i++)
Console.Write(Convert.ToChar(bb[i]));

tcpclnt.Close();
}

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

}


The above sample is a 1 to 1 server client system.

wondering if u can help/tell me how to change it into a MULTI-Threads server - clients system..?
