System.IO (system.dll)

class

This class allows you to listen to the filesystem and respond to different operations on it. To register a watch on files or directories, first set Path to the path you wish to watch. Next, set the Filter property. If you want to respond to all file changes, set it to an empty ("") string. To watch an individual file, set Filter to the filename. You can also use wildcards (such as * ) in the filename. You must then also set NotifyFilter to register the types of events you wish to be notified of. If you want to monitor the subdirectories as well, set IncludeSubdirectories . EnableRaisingEvents allows you to enable or disable the FileSystemWatcher . The watcher then exposes the following events: Changed , Created , Deleted , Disposed , Error , and Renamed . An Error is raised if too many events occur on a filesystem for the watcher to correctly monitor it.
