Shutdown Computing

In window, if i use a command: "shutdown -t 00 -s" then it will shutdown my computer.

Now, I want to use that command into C# program, How to?
Or have any another way to replace?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Try this out ...
