FileSystemWatcher OnOpened event

Question

In .Net how can I monitor if a file has been accessed (opened) by other programs? I can't see OnOpened event in FileSystemWatcher, so I assume it can not do that. Is there any other way to do it? It's clearly possible in Windows, is there some sort of hook available from .Net?

Answer 1

Check out the NotifyFilters property. You probably want to look for changes in access date/time.
