AccessControlType과 상관없이 지정한 규칙과 사용자가 같은 모든 액세스 제어 규칙을 제거한 다음 지정한 규칙을 추가합니다.

public:
 void ResetAccessRule(System::Security::AccessControl::RegistryAccessRule ^ rule);
public void ResetAccessRule (System.Security.AccessControl.RegistryAccessRule rule);
override this.ResetAccessRule : System.Security.AccessControl.RegistryAccessRule -> unit
Public Sub ResetAccessRule (rule As RegistryAccessRule)

매개 변수

rule
RegistryAccessRule

추가할 RegistryAccessRule입니다. 이 규칙에서 지정하는 사용자가 이 규칙이 추가되기 전에 제거할 규칙을 결정합니다.

예제

다음 코드 예제에서는 메서드 일치 ResetAccessRule 하는 사용자에 대 한 모든 규칙을 일치에 대 한 지정 된 규칙으로 대체 하는 방법을 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 키를 읽을 수 있도록 하는 새 규칙을 만들고 메서드를 사용하여 ResetAccessRule 사용자의 모든 규칙을 제거하고 새 규칙으로 바꿉니다.

참고

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