Storing TcpClient or NetworkStream for broadcast?

I'm storing TcpClient objects in a list, once client connects. When broadcasting to all connected clients, loop through the list of those and send data. The problem sometimes occurs while in a loop, throwing exception "Enumeration modified:" when one of those clients disconnects and its object is being disposed.

What would be a solution to that? Or simply store NetworkStream instead?

Thanks

You should use one of the ConcurrentCollections provided by .NET, e.g. ConcurrentBag or ConcurrentQueue.
