Im having problem putting an idea into practice. The idea is that i am running a client server application. The client connects and sends data (obviously). The users are dealt with at the server side by a class called UserCollection which stores there info. I also wanted each client to send all the running processes to the server so that i can select a client and show all the running processes from that user. The problem lies in how to link clients to ProcessCollections (thats the class used to store all the process via System.Diagnostics.Process.GetProcesses()). How do I link in the class, the processes in an array to the clients.

Thanks,

What is "send processes"? How a process can be sent?

Not only for network application parts, but simply for a pair of different processes, the code and hence classes can be the same, but objects, class instances are always different. Processes are thoroughly isolated from each other. For communication, you need IPC. And when it comes to sending data encapsulated in classes, serialization is involved. An instance (but generally, a whole object graph of arbitrary topology) is serialized into an array of bytes, sent to another process and deserialized on the other end.

Please see:
http://en.wikipedia.org/wiki/Serialization#.NET_Framework[^],

One most advanced and easy-to-use method of serialization is Data Contract: http://msdn.microsoft.com/en-us/library/ms733127.aspx[^].

Please see also my past answers on Data Contract:
How can I utilize XML File streamwriter and reader in my form application?[^],

deseralize a json string array[^].

Serialization is already embedded in "classical" .NET remoting, and Data Contract — in WPF:
