Примеры

В следующем примере демонстрируется регистрация ComponentRenameEventHandler события и обработка ComponentRename события.

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

Комментарии

При создании делегата ComponentRenameEventHandler вы определите метод, который будет обрабатывать событие. Чтобы связать событие с обработчиком событий, добавьте экземпляр делегата в событие. Обработчик событий вызывается всякий раз, когда происходит событие, если вы не удалите делегат. Дополнительные сведения о делегатах обработчика событий см. в разделе "Обработка и создание событий".
