Using asynchronous sockets in C#

How to have a listener for a socket in C#:

• Use System.Net.Sockets
• TcpListener listener=new TcpListener(System.Net.IPAddress.Parse("0.0.0.0"),2000);

• Create the following callback:

  protected void DoAcceptCallback(IAsyncResult ar){
  TcpListener tl = (TcpListener)ar.AsyncState;
  Socket s = tl.EndAcceptSocket(ar);
   
  //Log the traffic
  DataRow dr=traffic.NewRow();
  dr["ID"] = 0;
  dr["RemoteIP"] = s.RemoteEndPoint.ToString();
  traffic.Rows.Add(dr);
   
  s.Close();
  }
