 ## Examples  
  The following example creates an instance of the <xref:System.Timers.Timer?displayProperty=nameWithType> class, creates an event handler using a dynamic assembly, and hooks up the dynamic event handler. All actions are performed using late binding.

The ASP.NET infrastructure will then instantiate and call the handler when the corresponding request is received.

  The following example creates an <xref:System.Windows.Input.ExecutedRoutedEventHandler> that handles multiple commands. The handler checks the <xref:System.Windows.Input.ExecutedRoutedEventArgs.Command%2A> property on the <xref:System.Windows.Input.ExecutedRoutedEventArgs> to determine which method to call.
