RegistryKey.SetAccessControl(RegistrySecurity) 메서드

정의

네임스페이스:

Microsoft.Win32

어셈블리:

Microsoft.Win32.Registry.dll

Windows 액세스 제어 보안을 기존 레지스트리 키에 적용합니다.

public:
 void SetAccessControl(System::Security::AccessControl::RegistrySecurity ^ registrySecurity);

public void SetAccessControl (System.Security.AccessControl.RegistrySecurity registrySecurity);

member this.SetAccessControl : System.Security.AccessControl.RegistrySecurity -> unit

Public Sub SetAccessControl (registrySecurity As RegistrySecurity)

매개 변수

registrySecurity

RegistrySecurity

현재 하위 키에 적용할 액세스 제어 보안입니다.

예외

UnauthorizedAccessException

현재 RegistryKey 개체가 액세스 제어 보안이 적용된 키를 나타내고 호출자에게 ChangePermissions 권한이 없는 경우

ArgumentNullException

registrySecurity이(가) null인 경우

ObjectDisposedException

조작할 RegistryKey가 닫힌 경우. 닫힌 키는 액세스할 수 없습니다.

예제

다음 코드 예제에서는 테스트 키를 만듭니다. 현재 사용자는 허용 ReadKey 되며 Delete 권한은 허용되지만 거부되고 WriteKey 권한이 부여됩니다ChangePermissions. 이러한 권한에 따라 키를 조작하려는 후속 시도가 성공하거나 실패합니다.

키를 삭제하기 전에 코드가 일시 중지됩니다. 레지스트리 편집기로 전환하고 레지스트리 편집기를 사용하여 키에 액세스할 때 동일한 액세스 권한이 적용되는지 확인할 수 있습니다. (명령줄의 RunAs 를 사용하여 레지스트리 편집기와 샘플 코드를 관리자 권한이 없는 로컬 사용자로 실행하는 경우에 가장 적합합니다. 레지스트리 편집기에서는 특정 관리자가 해당 권한이 거부된 경우에도 관리자가 항상 권한을 변경할 수 있습니다. TestUser라는 로컬 사용자를 정의한 경우 명령은 runas /user:TestUser cmd 레지스트리 편집기를 실행한 다음 샘플 코드를 실행할 수 있는 명령 창을 엽니다.)

RegistrySecurity 에 registrySecurity 지정된 개체는 레지스트리 키에 대한 기존 보안을 대체합니다. 새 사용자에 대한 권한을 추가하려면 메서드를 GetAccessControl 사용하여 기존 액세스 제어 보안을 가져온 다음 수정합니다.
