I'm writing a program which make use of asynchronous sockets. My program
call Socket.BeginAccept() to make the .NET framework create a thread for me
and make it wait for an incomming connection while my program continue to
run normally. When a new connection comes in, my callback method (specified
by BeginAccept) is invoked in the context of the worker thread managed by
.NET. I call EndAccept to get the client connection. So far so good.

When I have a client connection, I place it into a variable Clients of type
ArrayList. That's where I have a problem: The variable Clients is accessed
from the accept callback within the context of a worker thread and it is
also accessed by the main thread. How do I manage thread synchronization ?
Do I have to use a critical section or some C# equivalent contruction ?

Any help appreciated.
