Represents the method that will handle the System.IO.FileSystemWatcher.Created, or System.IO.FileSystemWatcher.Deleted event of a FileSystemWatcher class.
[Visual Basic] Public Delegate Sub FileSystemEventHandler( _ ByVal sender As Object, _ ByVal e As FileSystemEventArgs _ ) [C#] public delegate void FileSystemEventHandler( object sender, FileSystemEventArgs e ); [C++] public __gc __delegate void FileSystemEventHandler( Object* sender, FileSystemEventArgs* e );
[JScript] In JScript, you can use the delegates in the NGWS frameworks, but you cannot define your own.
The declaration of your event-handling method must have the same parameters as the FileSystemEventHandler delegate declaration.
When you create a FileSystemEventHandler delegate, you identify the method that will handle the event. To associate the event with your event-handling method, add an instance of the delegate to the event. The event-handling method is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see TBD.
