[C#] TCP Modules

These are just some modules I wrote up, basic, but pretty full proof.

If there are any errors I'm sorry. I spent quite some time working the bugs out, although it may not seem like I have, I was learning as I was going.

Anyways, here's a demonstration video on what they do etc.

And here is the code :

If you use it, please say thanks or something :oui:

You can remove the namespaces if you want, it makes no difference.
