ElapsedEventHandlerobject

ElapsedEventHandler is a delegate in the .NET Framework that represents the method signature for an event handler that handles the Elapsed event of a Timer object. The Elapsed event is triggered when the interval specified for the Timer has elapsed. The ElapsedEventHandler delegate is used to define the method that will be called when the Elapsed event occurs.

The ElapsedEventHandler delegate takes two parameters: an object sender and an ElapsedEventArgs e. The sender parameter is a reference to the object that raised the event, which in this case is the Timer object. The ElapsedEventArgs parameter provides data for the Elapsed event, including the signal time, which is the time at which the event was triggered.

To use the ElapsedEventHandler delegate, you must define a method that matches the delegate's signature and then attach that method to the Elapsed event of a Timer object. The method will be called each time the interval specified for the Timer has elapsed, allowing you to perform any necessary actions in response to the event.

The ElapsedEventHandler delegate is part of the System.Timers namespace, which provides classes for working with timers and events in .NET applications. By using the ElapsedEventHandler delegate, you can create responsive and efficient applications that can handle events in a timely manner.
