Complete noob with C#

Hi, I'm new so please be gentle, or at least use some lube. I have been tinkering around lately with C#, just because.... well, just because. I am hoping to learn to make basic bots for MMO's, but I have no idea where to start, I know the basic concepts of the language, but when it comes to pinvokes and interope services I get completely lost.
Anybody have any tips on where i can go, or how to actually do it, when it comes to reading a process' memory and reporting it back to the app? Just for an example I would like to be able to type some text into notepad, and just have the application relay the text back to the app in the form of a label or a messagebox.

Whew thats a mouthful. Anyway, any help would be greatly appreciated.

I've done something remotely similar by allocating the last text sent through the chat system and read it into a variable i output into my own program's designated screen basically a Chat Bot or Logger. Process - > Address - > Variable - > IO using C++ on my old computer. If you can get a lead via google or something i could probably aid you through any difficulties you encounter but i haven't more then glanced at C# or worked on a similar project in quite some time to start you off myself, sorry. I'd also have to know what kindof botting you're doing besides your foundation on which i can help you build. I'll also refer one of my friends who is very good with C# and registered here lately to take notice of this thread.
