예제

다음 코드 예제에서는 메서드가 사용자 및 와 AccessControlType일치하는 모든 규칙을 제거하고 권한을 무시한다는 것을 보여 RemoveAccessRuleAll 줍니다.

이 예제에서는 개체를 EventWaitHandleSecurity 만들고, 현재 사용자에 대한 다양한 권한을 허용 및 거부하는 규칙을 추가한 다음, 추가 권한을 Allow 규칙에 병합합니다. 그런 다음 현재 사용자가 소유권을 가져올 수 있는 새 규칙을 만들고 해당 규칙을 사용하여 개체에서 EventWaitHandleSecurity 규칙을 제거 Allow 합니다.

설명

현재 EventWaitHandleSecurity 는 사용자와 값rule이 같은 AccessControlType 규칙을 검색합니다. 이 검색을 수행할 때 에 rule 지정된 모든 권한은 무시됩니다. 일치하는 모든 규칙이 제거됩니다. 일치하는 규칙을 찾을 수 없으면 아무 작업도 수행되지 않습니다.
