This is my first time trying to use a web API with C#, a friend asked me to make him a simple remote control app. I don't really know where to begin, I'm thinking I can create a
WebRequest filled with the proper info, is this going to work?

A demo of it can be found here: http://gamecp.com/?key=demo
and some API doc here: http://wiki.gamecp.com/API_Index
