file-locking

I've seen several of answers about using Handle or Process Monitor, but I would like to be able to find out in my own code (C#) which process is locking a file.

I have a nasty feeling that I'm going to have to spelunk around in the win32 API, but if anyone has already done this and can put me on the right track, I'd really appreciate the help.
