Açıklamalar

Bu sınıf, çağıranların genel derleme önbelleğine (GAC) kaydedildiğinden emin olmak için kullanılır.

İzin verilen bildirimin kapsamı, kullanılan değere SecurityAction bağlıdır.

Bir güvenlik özniteliği tarafından bildirilen güvenlik bilgileri, öznitelik hedefinin meta verilerinde depolanır ve sistem tarafından çalışma zamanında erişilir. Güvenlik öznitelikleri yalnızca bildirim temelli güvenlik için kullanılır. Kesinlik temelli güvenlik için ilgili izin sınıfını GacIdentityPermissionkullanın.

Öznitelikleri kullanma hakkında daha fazla bilgi için bkz . Öznitelikler.
