Have a look at the System.Diagnostics namespace. Lots of goodies in there!
System.Diagnostics.StackTrace t = new System.Diagnostics.StackTrace();
This is really good to have a poke around in to learn what’s going on under the hood.
I’d recommend that you have a look into logging solutions (Such as NLog, log4net or the Microsoft patterns and practices Enterprise Library) which may achieve your purposes and then some.
