## Remarks 
 When you create an <xref:System.IO.ErrorEventHandler> 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 [Handling and Raising Events](/dotnet/standard/events/). 



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