How to exit a process from Window Service in C#

I have two processes both developed in C#.

One of them is a Windows Service, the other one a normal windows based application.

What I intend to do is to exit the 开发者_开发技巧application from Service,

I don't intend to kill it forcibly, which i am able to do. I want to exit it gracefully.

Can i call the application_close function defined in my application through the service.

Process.CloseMainWindow() is what you're looking for, I believe.

Edit: If you really want to implement IPC, I've found utilizing message queues to be the most easily-implemented solution in windows, but even that isn't very simple, and I wouldn't recommend it when all you want is resource cleanup on exit.
