Listening on multiple ports on a single server

Hello,

i have to program a server, where I have at most (let say) 4 Clients. and each Client is to be listened to a particular port, means a port is assigned to a Client, and that Client will send all data to that port only.

it means i have to keep all 4 ports in listen mode at a time.

Now i am able to establish communication between a Client and Server on a single port, send and receive data.

I searched and found something similar here (but its for Java, and i need something similar for .Net) http://stackoverflow.com/questions/5079172/java-server-multiple-ports[^]

please Help, how can i create such Socket Connection.

I need to do this :

1. Start server;
2. Listen for incoming connections on several ports;
3. Identify the port being connected to;
a. If port 1, start a thread listening to client and outputting message type x
b. If port 2, start a thread listening to client and outputting message type y

thanks in advance.
