One of best and unknown built in string function included in .NET is String.Split(). It has come in quite handy for my in the last 2 years that I thought I'd share. Pretty basic example here...and for my first post, I thought I'd throw in a little File IO (for free of course)!

Modern J2EE containers do a nice job of letting you deploy a jarfile with your code and have a lib directory full of jarfiles like this, but what if you just want to run a quick client from the command line?

Here's what you do:
