RegistrySecurity.RemoveAccessRuleAll(RegistryAccessRule) 메서드

정의

네임스페이스:

System.Security.AccessControl

어셈블리:

Microsoft.Win32.Registry.dll

지정한 규칙과 사용자 및 AccessControlType(허용 또는 거부)이 같은 모든 액세스 제어 규칙을 검색하여 제거합니다.

public:
 void RemoveAccessRuleAll(System::Security::AccessControl::RegistryAccessRule ^ rule);

public void RemoveAccessRuleAll (System.Security.AccessControl.RegistryAccessRule rule);

override this.RemoveAccessRuleAll : System.Security.AccessControl.RegistryAccessRule -> unit

Public Sub RemoveAccessRuleAll (rule As RegistryAccessRule)

매개 변수

rule

RegistryAccessRule

검색할 사용자 및 RegistryAccessRule을 지정하는 AccessControlType입니다. 이 규칙에서 지정한 모든 권한, 상속 플래그 또는 전파 플래그는 무시됩니다.

예외

ArgumentNullException

rule이(가) null인 경우

예제

다음 코드 예제에서는 메서드가 RemoveAccessRuleAll 사용자 및 와 AccessControlType일치하는 모든 규칙을 제거하고 권한 및 플래그를 무시하는 것을 보여 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 소유권을 가져올 수 있는 새 규칙을 만들고 해당 규칙을 메서드에 RemoveAccessRuleAll 전달하여 액세스를 허용하는 두 규칙을 제거합니다.

참고

이 예제에서는 보안 개체를 개체에 RegistryKey 연결하지 않습니다. RegistryKey.GetAccessControl 메서드 및 메서드를 RegistryKey.SetAccessControl 참조하세요.

설명

현재 RegistrySecurity 는 사용자와 AccessControlType 값 rule이 같은 규칙을 검색합니다. 이 검색을 수행할 때 에 지정된 rule 모든 권한, 상속 플래그 또는 전파 플래그는 무시됩니다. 일치하는 규칙을 찾을 수 없으면 아무 작업도 수행되지 않습니다.

예를 들어 사용자에게 상속 및 전파 플래그가 다른 다양한 권한을 허용하는 여러 규칙이 있는 경우 임의의 권한 및 플래그를 사용하여 사용자 및 AccessControlType.Allow를 지정하는 개체를 만들고 RegistryAccessRule 해당 규칙을 메서드에 RemoveAccessRuleAll 전달하여 이러한 모든 규칙을 제거할 수 있습니다.
