Detect File Read in C#

Question

I\'m using FileSystemWatcher to check when a file is modified or deleted, but I\'m wondering if there is any way to check when a file is read by another application.

Answer 1

There is SysInternals' program FileMon... It can trace every file access in the system. If you can find its source, and understand what win32 hooks it uses, you might marshal those functions in C# and get what you want.
