What was wrong with just reading on System.Console? :-)

Hell, no! Your loop is polling and is considered a very bad thing, especially in UI. What you need is this:

C#

System.Console.Write("Press any key...");
System.Console.ReadKey(true);

The ReadKey call is blocking. Your thread will be put in wait state wasting not CPU time, will be waken up only when you actually press a key, all the way from triggering a hardware interrupt in OS kernel (or if you abort the thread or the whole process).
