Multiple Clients in Client Server app in C#

Multiple Clients in Client Server app in C#

using resources at http://www.developerfusion.com i came up with the
following server code. It works well for single client. How can i make it
for multiple clients. I tried adding array and different instances of the
beiginreceive but was unable to. The server code:
class Program
{
public static AsyncCallback pfnWorkerCallBack;
public static Socket m_socListener;
public static Socket m_socWorker;
static void Main(string[] args)
{
try
{
//create the listening socket...
m_socListener = new Socket(AddressFamily.InterNetwork,
SocketType.Stream, ProtocolType.Tcp);
IPEndPoint ipLocal = new IPEndPoint(IPAddress.Any, 8221);
//bind to local IP Address...
m_socListener.Bind(ipLocal);
Console.WriteLine("UCManager Started");
//start listening...
m_socListener.Listen(4);
// create the call back for any client connections...
m_socListener.BeginAccept(new AsyncCallback(OnClientConnect),
null);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
Console.ReadLine();
}
public static void OnClientConnect(IAsyncResult asyn)
{
try
{
m_socWorker = m_socListener.EndAccept(asyn);
WaitForData(m_socWorker);
}
catch (Exception se)
{
Console.WriteLine(se.Message);
}
}
public class CSocketPacket
{
public System.Net.Sockets.Socket thisSocket;
public byte[] dataBuffer = new byte[1];
}
public static void WaitForData(System.Net.Sockets.Socket soc)
{
try
{
if (pfnWorkerCallBack == null)
{
pfnWorkerCallBack = new AsyncCallback(OnDataReceived);
}
CSocketPacket theSocPkt = new CSocketPacket();
theSocPkt.thisSocket = soc;
// now start to listen for any data...
soc.BeginReceive(theSocPkt.dataBuffer, 0,
theSocPkt.dataBuffer.Length, SocketFlags.None,
pfnWorkerCallBack, theSocPkt);
}
catch (SocketException se)
{
Console.WriteLine(se.Message);
}
}
public static void OnDataReceived(IAsyncResult asyn)
{
try
{
CSocketPacket theSockId = (CSocketPacket)asyn.AsyncState;
//end receive...
int iRx = 0;
iRx = theSockId.thisSocket.EndReceive(asyn);
char[] chars = new char[iRx + 1];
Decoder d = Encoding.UTF8.GetDecoder();
int charLen = d.GetChars(theSockId.dataBuffer, 0, iRx, chars, 0);
String szData = new String(chars);
Console.WriteLine(szData);
int code = Convert.ToInt32(szData);
WaitForData(m_socWorker);
}
catch (Exception se)
{
Console.WriteLine(se.Message);
}
}
}
}
