How to make a running excutable delete its own file

For example,

I have an excutable TrashClean.exe running. I want it to delete all files I don't want and also delete itself (TrashClean.开发者_如何学Cexe on hard drive) at last step.

I am wondering if it's possible in C#?

Please see How To Make Your Application Delete Itself Immediately:

I'm sure you've all said to yourself or someone at the office at one point or another, "<snort> You idiot. Don't you know a Windows application can't delete itself? I bet you don't even know how to type high ASCII characters using the ALT key and the number pad, gahhhh.."

Sure, there are ways to have a file delete itself on the next reboot... And you can even resort to an external program or batch file to do the work. But I just came up with a nifty way of doing it without leaving a visible trace that the application ever existed!
