Ejemplos

En el ejemplo siguiente se muestra cómo registrar un ComponentRenameEventHandler evento y controlarlo ComponentRename .

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

Comentarios

Cuando se crea un delegado ComponentRenameEventHandler, se identifica el método que controlará el evento. Para asociar el evento al controlador, se debe agregar una instancia del delegado al evento. Siempre que se produce el evento, se llama a su controlador, a menos que se quite el delegado. Para obtener más información sobre los delegados del controlador de eventos, consulte Control y generación de eventos.
