FileSystemEventHandler Delegate


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Represents the method that will handle the Changed, Created, or Deleted event of a FileSystemWatcher class.

Namespace:   System.IO
Assembly:  System (in System.dll)

type FileSystemEventHandler = 
    delegate of 
        sender:Object *
        e:FileSystemEventArgs -> unit


Type: System.Object

The source of the event.

Type: System.IO.FileSystemEventArgs

The FileSystemEventArgs that contains the event data.

When you create a FileSystemEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see Handling and Raising Events.

The following example shows how to create a FileSystemWatcher to monitor file changes (creates, deletes, renames, changes) occurring on a disk drive. The example also shows how to properly receive error notifications.
