ElapsedEventHandler Delegate

Represents the method that will handle the Elapsed event of a Timer.

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

type ElapsedEventHandler = 
    delegate of  
        sender:Object * 
        e:ElapsedEventArgs -> unit

Parameters

sender
Type: System.Object

The source of the event.

e
Type: System.Timers.ElapsedEventArgs

An ElapsedEventArgs object that contains the event data.

When you create an ElapsedEventHandler 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 code example sets up an event handler for the Timer.Elapsed event, creates a timer, and starts the timer. The event handler has the same signature as the ElapsedEventHandler delegate. The event handler displays the SignalTime property each time it is raised.
