C# Relationship between class and socket

Can't really explain the situation in the best words but here is what I am dealing with.

I have a loop that cycles through the following code:

Code:

---

public IList<Socket> Select(ICollection<Socket> listeners)
        {
            var tcpListeners = new List<Socket>(from listener in listeners
                                                    where listener.Poll(-1, SelectMode.SelectRead)
                                                    select listener);

           
            return tcpListeners;
        }

---

All connections that wont block the socket (that are ready to be read from) are added to a list. Then I have a foreach loop that cycles through the sockets to read from each one and process it. Say I have a class Connection that has data in it related to that specific socket. The class is initiated with the socket. How do I pull up the right class with the socket so I can pull information from it?

Okay nevermind I solved it by making a Connection list and checking each connection class socket.
