매개 변수

반품

true 호환되는 규칙을 찾았으면 이고, 그렇지 않으면 false.

예외

예제

다음 코드 예제에서는 메서드가 RemoveAccessRule 호환되는 규칙에서 권한을 제거하는 방법과 메서드가 AddAccessRule 호환되는 규칙과 권한을 병합하는 방법을 보여 줍니다.

이 예제에서는 개체를 RegistrySecurity 만들고 현재 사용자 RegistryRights.ReadKey 권한을 허용하는 규칙을 추가합니다. 그런 다음, 첫 번째 규칙과 동일한 상속 및 전파 권한을 가진 사용자에게 RegistryRights.SetValue권한을 부여하는 규칙을 만들고 메서드를 사용하여 RemoveAccessRule 개체에서 RegistrySecurity 이 새 규칙을 제거합니다. SetValue 는 구성 요소 ReadKey이므로 호환되는 규칙에서 제거됩니다. 개체의 RegistrySecurity 규칙이 표시되고 나머지 구성 요소가 ReadKey표시됩니다.

그런 다음 예제 코드는 메서드를 RemoveAccessRule 호출하여 개체의 SetValue 규칙에 오른쪽을 다시 병합합니다 RegistrySecurity .

설명

현재 RegistrySecurity 는 사용자와 값AccessControlType이 같은 rule 규칙을 검색합니다. 이러한 규칙을 찾을 수 없으면 아무 작업도 수행되지 않고 메서드가 반환됩니다 false. 일치하는 규칙이 발견되면 해당 상속 및 호환성 플래그가 지정된 rule플래그와의 호환성을 확인합니다. 호환되는 규칙을 찾을 수 없으면 아무 작업도 수행되지 않고 메서드가 반환됩니다 false. 호환 플래그가 있는 규칙을 발견하면 지정된 rule 권한이 호환되는 규칙에서 제거되고 메서드가 반환됩니다 true. 호환되는 규칙에 포함되지 않은 권한을 지정하는 경우 rule 해당 권한과 관련하여 아무런 조치도 취하지 않습니다. 호환되는 규칙에서 모든 권한이 제거되면 현재 RegistrySecurity 개체에서 전체 규칙이 제거됩니다.
