예제

다음 코드 예제에서는 메서드가 사용자와 SetAccessRuleAccessControlType사용자 모두와 일치하는 모든 규칙을 제거하고 권한 및 플래그를 무시하고 해당 규칙을 대체rule한다는 것을 보여 rule 줍니다.

이 예제에서는 개체를 RegistrySecurity 만들고 다른 상속 및 전파 플래그를 사용하여 현재 사용자에 대한 다양한 권한을 허용하고 거부하는 규칙을 추가합니다. 그런 다음 현재 사용자가 키를 읽을 수 있도록 하는 새 규칙을 만들고 이 메서드를 사용하여 SetAccessRule 액세스를 허용하는 두 규칙을 제거하고 새 규칙으로 바꿉니다. 액세스를 거부하는 규칙은 영향을 받지 않습니다.

설명

지정된 규칙이 Allow있는 경우 이 메서드의 효과는 지정된 사용자에 대한 모든 Allow 규칙을 제거하고 지정된 규칙으로 바꾸는 것입니다. 지정된 규칙이 Deny있는 경우 지정된 사용자에 대한 모든 Deny 규칙이 지정된 규칙으로 대체됩니다.

사용자가 지정한 규칙과 AccessControlType 일치하는 규칙이 rule 없으면 추가됩니다.
