TCP, channels, sockets sync or async ?

[nahumtakum]

Hi everyone! I want to write an application which has a server and some clients. I would like them to communicate with tcp/ip. I would like to send and recieve all kinds of data. I have read about TCPListener, TCPClient, channels, sockets sync and async methods. What are the diffrences between those methods ? Which is the better way ? Thanks.

If your wanting to talk RAW TCP/IP - then use the Listner and either the client or socket class. Example: TcpListener tcplpop = new TcpListener(110); tcplpop.Start(); Socket s = tcplpop.AcceptSocket() // Blocks until someone calls s.Send(...) s.Receive(...)

What is the difference between version no.1: TcpListener tcplpop = new TcpListener(110); tcplpop.Start(); Socket s = tcplpop.AcceptSocket() // Blocks until someone calls s.Send(...) s.Receive(...) and version no.2: IPEndPoint dbg_EndPoint = new IPEndPoint(ipAddress, dbg_port); Socket dbg_listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp ); dbg_listener.Bind(dbg_EndPoint); dbg_listener.Listen(num_of_devices); dbg_listener.BeginAccept( new AsyncCallback(AcceptCallback), dbg_listener ); // Get the socket that handles the client request. Socket listener = (Socket) ar.AsyncState; Socket handler = listener.EndAccept(ar); // Create the state object. StateObject state = new StateObject(); state.workSocket = handler; handler.BeginReceive( state.buffer, 0, StateObject.BufferSize, 0, new AsyncCallback(ReadCallback), state); Thanks.
