Code Snippet for ArgumentNullException

I got a chance to see BradA give his talk at TriNUG Wednesday night, and in honor of that (specifically, the part where he explains why an API may do a disservice to its consumers if it needs an argument to be non-null and just lets null refs happen instead of argument checking) is a quickie snippet for ArgumentNullException throwing on null parameters.

It's obviously not ground-breaking stuff, but hopefully the easier that adding the checking becomes on developers, the more likely it is they'll provide it, right? :)
