    .NET 2.0 Socket (Connection check)

    Hey guys. I created a multiple client/server application using sockets in c#. Everything works just fine. Now can you please help me create a code that will allow a client to check if another client is connected to the server(By IP)? I have an idea but I don't know how to implement it. I want something like that:

    Client #1 has connected.
    Client #2 has connected.

    Client #1 sends to server: "check 45.56.128.20"

    if client #2 is connected, do nothing. Else:

    Server sends to Client #1: "The client is not connected".

    My server size code:
    http://pastebin.com/vmwJFxFt

    My client side code:
    http://pastebin.com/YD28bNCg

    (I did not write the server&client codes)

    Thank you!

    How do you know client2 even exists?

    Asuming you have an answer to the first question, in your server code, keep a list of connected or previously connected clients. Use the list to send messages to the connected clients.

    I already have a list in server, List Socket _clientSockets. But I don't know how to send a message to a specific IP address as I have only Socket objects.

    thank you

    Are your storing the IP addresses in the list?
