EventWaitHandleSecurity.AddAccessRule(EventWaitHandleAccessRule) 메서드

정의

새 규칙을 병합할 수 있는 일치하는 액세스 제어 규칙을 검색합니다. 아무 것도 발견되지 않으면 새 규칙을 추가합니다.

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

매개 변수

rule
EventWaitHandleAccessRule

추가할 액세스 제어 규칙입니다.

예외

rule이(가) null인 경우

예제

다음 코드 예제에서는 규칙과 규칙 간의 Allow 분리를 보여 줍니다 Deny . 호환되는 규칙의 권한 조합을 보여 줍니다. 이 예제에서는 개체를 EventWaitHandleSecurity 만들고, 현재 사용자에 대한 다양한 권한을 허용 및 거부하는 규칙을 추가하고, 결과 규칙 쌍을 표시합니다. 그런 다음, 이 예제에서는 현재 사용자에 대한 새 권한을 허용하고 결과를 표시하여 새 권한이 기존 규칙과 병합됨을 Allow 보여 줍니다.

참고

이 예제에서는 보안 개체를 개체에 EventWaitHandle 연결하지 않습니다. 보안 개체를 연결하는 예제는 및 EventWaitHandle.SetAccessControl에서 EventWaitHandle.GetAccessControl 찾을 수 있습니다.

설명

메서드는 AddAccessRule 사용자 또는 그룹이 동일하고 와 동일한 AccessControlTyperule규칙을 검색합니다. 찾을 수 없는 경우 가 rule 추가됩니다. 일치하는 규칙이 발견되면 의 권한이 rule 기존 규칙과 병합됩니다.
