thanks for posting this code.....
would like to point out one thing...

//Shutdown computer
4)ProcessReques t("shutdown.exe", "-s -t 0");

here it should be
4) PerformOperation ("shutdown.exe", "-s -t 0");
bcz ProcessRequest is defined no where....

And also we need to use following namespaces to make this code working.
using System.Diagnostics;
using System.IO;
