About FileSystemWatcher !!

[MingChih Tsai]

Hi there,

I can use FileSystemWatcher class to monitor system io, but how should I do
if I want to cancel the system delete process on my OnDelete event ?

Thanks for the reply !!

Paul,

You can't do this with the FileSystemWatcher, as Watchers never
interfere (it's a comic book reference). Seriously though, the
FileSystemWatcher doesn't have the abilty to cancel out actions that you
observe.

The only way to really cancel this is to write a system level driver,
which is something you can not do in .NET.

You will have to use unmanaged code if you want to do something like
that.

Hope this helps.
