Registry Event Notification with .NET

[Elder Hyde]

Hey all,

I need to get a notification whenever something changes in the registry.
However, I can't find anything that supports this in Microsoft.Win32,
although I know that the C version of the REgistry API does have a
method (oops, function) called RegNotifyChangeKeyValue that allows this.

I can do this if I really have to, but I don't feel like Waiting For a
Single Object jsut to get a registry event. Is there any straightforward
way of doing this in .NET (i.e.: the registry-equivalent of
FileSystemWatcher), or I really have exhausted my options?

Thanks!
Elder

You can call RegNotifyChangeKeyValue, and use the .NET ThreadPool to wait
for the Win32 handle. When the handle is signalled, you are notified with a
callback. There is a code sample of this at [1].

There isn't any inbuilt .NET support for registry change notification.
