Açıklamalar

Bu yöntem aşırı yüklemesini çağırmak, GetAccessControl yöntemi aşırı yüklemesini çağırmaya ve AccessControlSections.Access | AccessControlSections.Owner | AccessControlSections.Group (Visual Basic'teAccessControlSections.AccessOrAccessControlSections.OwnerOrAccessControlSections.Group) erişim denetimi bölümlerini belirtmeye eşdeğerdir.

ACL, belirli bir dosya veya dizin üzerinde belirli eylemlere sahip olan veya olmayan kişileri ve grupları açıklar. Daha fazla bilgi için bkz. Nasıl yapılır: Erişim Denetimi Listesi Girdilerini Ekleme veya Kaldırma.
