how do you clear the console window in c#?
Dead easy (if you already know the code, otherwise it a tough one).
I have the code at work and I'll post it here tomorrow, but if you cant wait that long, go to
http://support.microsoft.com/default...b;en-us;319257
and use the code they have there. It works fine.
Sorry, I completely forgot.
Paste this into a new class file and create an instance of it from your main program then call its Clear() method.
