ChangePermissions	262144	레지스트리 키와 관련된 액세스 규칙 및 감사 규칙을 변경할 권한입니다.
CreateLink	32	시스템에서 사용하도록 예약되었습니다.
CreateSubKey	4	레지스트리 키의 하위 키를 만들 권한입니다.
Delete	65536	레지스트리 키를 삭제할 권한입니다.
EnumerateSubKeys	8	레지스트리 키의 하위 키를 나열할 권한입니다.
ExecuteKey	131097	ReadKey와 동일합니다.
FullControl	983103	레지스트리 키에 대한 모든 권한을 실행하고 해당 액세스 규칙 및 감사 규칙을 수정할 권한입니다.
Notify	16	레지스트리 키에 대한 변경 알림을 요청할 권한입니다.
QueryValues	1	레지스트리 키의 이름/값 쌍을 쿼리할 권한입니다.
ReadKey	131097	레지스트리 키의 이름/값 쌍을 쿼리하고, 변경 알림을 요청하고, 하위 키를 열거하고, 해당 액세스 규칙과 감사 규칙을 읽을 권한입니다.
ReadPermissions	131072	레지스트리 키에 대한 액세스 규칙 및 감사 규칙을 열고 복사할 권한입니다.

예제

다음 코드 예제에서는 RegistryRights 열거형입니다. 이 코드는 현재 사용자 ReadKey 및 삭제 액세스 권한을 허용하지만 ChangePermissions 및 WriteKey 권한을 거부하는 테스트 키를 만듭니다. 이러한 권한에 따라 키를 조작하려는 후속 시도가 성공하거나 실패합니다.

키를 삭제하기 전에 코드가 일시 중지됩니다. 레지스트리 편집기(Regedit.exe 또는 Regedt32.exe)로 전환하고 레지스트리 편집기를 사용하여 키에 액세스할 때 동일한 액세스 권한이 적용되는지 확인할 수 있습니다.

이 예제는 명령줄의 RunAs 를 사용하여 레지스트리 편집기 및 샘플 코드를 관리자 권한이 없는 로컬 사용자로 실행하는 경우에 가장 적합합니다. 예를 들어 TestUser라는 로컬 사용자를 정의한 경우 명령은 runas /user:TestUser cmd 레지스트리 편집기를 실행할 수 있는 명령 창을 연 다음 예제 코드를 엽니다.

설명

개체를 RegistryRights 만들 RegistrySecurity 때 열거형을 사용하여 레지스트리 액세스 권한을 지정합니다. 레지스트리 키에 액세스 권한을 적용하려면 먼저 개체에 개체를 RegistrySecurity 추가 RegistryAccessRule 한 다음 메서드 또는 메서드의 적절한 오버로드를 사용하여 RegistryKey.SetAccessControl 개체를 키에 RegistryKey.CreateSubKey 연결 RegistrySecurity 합니다.
