member this.SetAccessControl : System.Security.AccessControl.DirectorySecurity -> unit
Public Sub SetAccessControl (directorySecurity As DirectorySecurity)

설명

ACL(액세스 제어 목록)은 지정된 파일 또는 디렉터리에 대한 특정 작업에 대한 권한이 있거나 없는 개인 및 그룹에 대해 설명합니다. 자세한 내용은 방법: 액세스 제어 목록 항목 추가 또는 제거참조하세요.

SetAccessControl 메서드는 암호화되지 않은 ACL 목록을 나타내는 파일에 ACL 항목을 적용합니다.

주의

directorySecurity 지정된 ACL은 디렉터리에 대한 기존 ACL을 대체합니다. 새 사용자에 대한 권한을 추가하려면 GetAccessControl 메서드를 사용하여 기존 ACL을 가져오고 수정합니다.

SetAccessControl 메서드는 개체를 만든 후에 수정된 DirectorySecurity 개체만 유지합니다. DirectorySecurity 개체가 수정되지 않은 경우 파일에 유지되지 않습니다. 따라서 한 파일에서 DirectorySecurity 개체를 검색하고 동일한 개체를 다른 파일에 다시 적용할 수 없습니다.

한 파일에서 다른 파일로 ACL 정보를 복사하려면 다음을 수행합니다.

  1. GetAccessControl 메서드를 사용하여 소스 파일에서 DirectorySecurity 개체를 검색합니다.

  2. 대상 파일에 대한 새 DirectorySecurity 개체를 만듭니다.

  3. 원본 DirectorySecurity 개체의 GetSecurityDescriptorBinaryForm 또는 GetSecurityDescriptorSddlForm 메서드를 사용하여 ACL 정보를 검색합니다.

  4. SetSecurityDescriptorBinaryForm 또는 SetSecurityDescriptorSddlForm 메서드를 사용하여 3단계에서 검색된 정보를 대상 DirectorySecurity 개체에 복사합니다.

  5. SetAccessControl 메서드를 사용하여 대상 DirectorySecurity 개체를 대상 파일로 설정합니다.
