Örnekler

Aşağıdaki örnekte sınıfının ve Uninstall Install yöntemleri gösterilmektedirTransactedInstaller TransactedInstaller.

Bu örnek, Installutil.exe (Yükleyici Aracı) ile benzer bir uygulama sağlar. Derlemeleri, söz konusu derlemeden önceki seçeneklerle yükler. Bir derleme için bir seçenek belirtilmezse, listede önceki bir derleme varsa, önceki derlemenin seçenekleri kullanılır. "/u" veya "/uninstall" seçeneği belirtilirse, derlemeler kaldırılır. "/?" veya "/help" seçeneği sağlanırsa, yardım bilgileri konsolda görüntülenir.

Açıklamalar

Daha önce tamamlanmış bir yüklemeyi kaldırmak için bu yöntemi çağırabilirsiniz. Bu Uninstall yöntem, yükleme sırasında ayarlanan kaynakları kaldırmak için özelliğindeki her yükleyicinin Installers yöntemini çağırırUninstall. Kaldırma sırasındaki tüm özel durumlar yoksayılır.

Not

ve Commit yöntemleri yüklemelerden sonra bilgisayarın durumunu kaydetse Install de, yükleme tamamlandıktan sonra parametresini savedState içeren IDictionary dosya bir noktada silinmiş olabilir. Dosya silinirse savedState parametresi olur null.
