설명

참고

ResourcePermissionBase 클래스에서는 서수 정렬 규칙을 사용하여 문자열을 비교하며 이때 문자열의 대/소문자는 구분하지 않습니다.

상속자 참고 사항 ResourcePermissionBase에서 상속될 때 최소한 세 개의 생성자를 제공하고 두 개의 속성을 설정한 다음 셋째 속성을 제공해야 합니다. 필요한 생성자는 기본 생성자, PermissionState를 매개 변수로 사용하는 하나의 생성자 및 속성 값을 사용하는 만큼의 생성자입니다. 설정해야 할 속성은 PermissionAccessType 및 TagNames입니다. 필요한 셋째 속성은 사용 권한 항목을 반환하는 속성입니다. 이 클래스의 구현 예제는 PerformanceCounterPermission을 참조하십시오. PerformanceCounterPermission에서 TagNames 속성은 "Machine" 및 "Category" 전용으로 설정되고, PermissionAccessType 속성은 PerformanceCounterPermissionAccess의 형식 전용으로 설정되고, PermissionEntries 속성은 사용 권한 항목을 반환합니다.

예제

다음 예제는 ResourcePermissionBase 클래스에서 상속됩니다. 네 가지 종류의 생성자가 구현됩니다. 이 예제에서는 또한 MailslotPermissionEntry라는 클래스를 구현합니다. PermissionAccessType 속성은 MailslotPermissionEntry 형식 전용으로 설정됩니다. TagNames 속성은 "Name" 및 "Machine" 전용으로 설정됩니다.
