Cache Dependency Question

[Jason Dean]

Hello,

Can anybody tell me if it's possible to create a dependency on the contents
of a directory? For example, I've just built and ASP.NET image rotator that
uses System.IO to loop through all the files inside a directory, stuff them
into an array, then put that array into the ASP.NET data cache.

I want the cache to expire and be repopulated when a file is added or
removed from that image directory.

Thanks for any help with this issue.

Look up FileSystemWatcher in help.

Found an easier fix. Just insert the path name like so...

Cache.Insert("Name", myArrayList, New CacheDependency("C:\Images")
Cache will update itself if any files are added, deleted, or edited.
