Esempio

Nell'esempio seguente viene illustrata la registrazione di un oggetto ComponentRenameEventHandler e la gestione dell' ComponentRename evento.The following example demonstrates registering a ComponentRenameEventHandler and handling the ComponentRename event.

public:
   void LinkComponentRenameEvent( IComponentChangeService^ changeService )
   {
      // Registers an event handler for the ComponentRename event.
      changeService->ComponentRename += gcnew ComponentRenameEventHandler(
         this, &ComponentRenameEventHandlerExample::OnComponentRename );
   }

private:
   void OnComponentRename( Object^ /*sender*/, ComponentRenameEventArgs^ e )
   {
      // Displayss component renamed information on the console.
      Console::WriteLine( "Type of the component that has been renamed: " +
         e->Component->GetType()->FullName );
      Console::WriteLine( "New name of the component that has been renamed: " +
         e->NewName );
      Console::WriteLine( "Old name of the component that has been renamed: " +
         e->OldName );
   }
public void LinkComponentRenameEvent(IComponentChangeService changeService)
{
    // Registers an event handler for the ComponentRename event.
    changeService.ComponentRename += new ComponentRenameEventHandler(this.OnComponentRename);            
}

private void OnComponentRename(object sender, ComponentRenameEventArgs e)
{
    // Displayss component renamed information on the console.           
    Console.WriteLine("Type of the component that has been renamed: "+e.Component.GetType().FullName);                  
    Console.WriteLine("New name of the component that has been renamed: "+e.NewName);
    Console.WriteLine("Old name of the component that has been renamed: "+e.OldName);
}
Public Sub LinkComponentRenameEvent(ByVal changeService As IComponentChangeService)
    ' Registers an event handler for the ComponentRename event.
    AddHandler changeService.ComponentRename, AddressOf Me.OnComponentRename
End Sub

Private Sub OnComponentRename(ByVal sender As Object, ByVal e As ComponentRenameEventArgs)
    ' Displays component renamed information on the console.           
    Console.WriteLine(("Type of the component that has been renamed: " + e.Component.GetType().FullName))
    Console.WriteLine(("New name of the component that has been renamed: " + e.NewName))
    Console.WriteLine(("Old name of the component that has been renamed: " + e.OldName))
End Sub

Commenti

Quando si crea un delegato ComponentRenameEventHandler, si identifica il metodo che gestirà l'evento.When you create a ComponentRenameEventHandler delegate, you identify the method that will handle the event. Per associare l'evento al gestore eventi in uso, aggiungere all'evento un'istanza del delegato.To associate the event with your event handler, add an instance of the delegate to the event. Il gestore eventi viene chiamato ogni volta che si verifica l'evento, a meno che non venga rimosso il delegato.The event handler is called whenever the event occurs, unless you remove the delegate. Per ulteriori informazioni sui delegati del gestore eventi, vedere gestione e generazione di eventi.For more information about event-handler delegates, see Handling and Raising Events.
