Örnekler

Aşağıdaki örnekte ve SetAccessControl yöntemleri kullanılarak GetAccessControl bir erişim denetim listesi (ACL) girdisi eklenip bir dizinden ACL girişi kaldırılacaktır. Bu örneği çalıştırmak için geçerli bir kullanıcı veya grup hesabı sağlamanız gerekir.

Açıklamalar

yöntemi, SetAccessControl erişim denetim listesi (ACL) girdilerini, kaynağı olmayan ACL listesini temsil eden bir dosyaya uygular.

Dikkat

parametresi için directorySecurity belirtilen ACL, dizinin mevcut ACL'sinin yerini alır. Yeni bir kullanıcıya izin eklemek için yöntemini kullanarak GetAccessControl mevcut ACL'yi alın ve değiştirin.

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

SetAccessControl yöntemi yalnızca DirectorySecurity nesne oluşturulduktan sonra değiştirilmiş nesneleri kalıcı hale döndürür. Bir DirectorySecurity nesne değiştirilmediyse, bir dosyada kalıcı olmaz. Bu nedenle, bir dosyadan nesne almak ve aynı nesneyi başka bir DirectorySecurity dosyaya yeniden uygulamak mümkün değildir.

ACL bilgilerini bir dosyadan diğerine kopyalamak için:

  1. GetAccessControl Nesnesini kaynak dosyadan almak DirectorySecurity için yöntemini kullanın.

  2. Hedef dosya için yeni DirectorySecurity bir nesne İçerik Oluşturucu.

  3. GetSecurityDescriptorBinaryForm ACL bilgilerini almak için kaynak DirectorySecurity nesnenin veya GetSecurityDescriptorSddlForm yöntemini kullanın.

  4. SetSecurityDescriptorBinaryForm 3. adımda alınan bilgileri hedef DirectorySecurity nesneye kopyalamak için veya SetSecurityDescriptorSddlForm yöntemini kullanın.

  5. yöntemini kullanarak hedef DirectorySecurity nesneyi hedef dosyaya SetAccessControl ayarlayın.

NTFS ortamlarında ReadAttributes ve ReadExtendedAttributes kullanıcının üst klasörde hakları varsa kullanıcıya ListDirectory verilir. ve ReadExtendedAttributes'yi reddetmek ReadAttributes için üst dizinde reddedinListDirectory.
