Public Function Resolve (evidence As Evidence) As PolicyStatement

매개 변수

evidence

Evidence

Evidence을 확인하는 데 사용되는 PolicyLevel입니다.

반환

PolicyStatement

결과 PolicyStatement입니다.

예외

설명

Resolve 는 정책 수준에 대한 기본 정책 평가 작업입니다. 증명 정보 집합을 입력으로 지정하면 이 메서드는 루트에서 시작하여 일치하는 대로 작동 중인 코드 그룹의 멤버 자격 조건을 테스트합니다. 일치하는 코드 그룹에서 발생하는 사용 권한의 조합은 반환되는 을 PolicyStatement 생성합니다.

코드에 권한을 부여할 때 보안 정책은 권한에 대한 코드 요청과 함께 적용 가능한 모든 정책 수준에 대해 확인된 정책 문을 사용합니다.
