C# create multi threaded socket server and select client/connection

Question

Currently, I'm programming in C#, I would like to modify the code below to isolate one client connection. so like creating a break-out room from the main pool.

Below are 2 files, one is just the basic standard .NET Framework Console App Program.cs file; the other is the server file. Combined, they both can make a multi-threaded server, but I would like one that allows me to also select a client to connect to in case if I were to create a remote control application as my friend did.

On a side note, I would like to share that I want to be able to connect to a client by entering connect [1,2,3,etc..] into the console.

If you answer, please put some code, It would really, really help. I learn a lot better by looking att the code rather than reading documentation.
