PolicyLevel.Resolve(Evidence) 메서드

정의

네임스페이스:

System.Security.Policy

어셈블리:

정책 수준에 대한 증명 정보를 기반으로 하여 정책을 확인하고 결과 PolicyStatement를 반환합니다.

public:
 System::Security::Policy::PolicyStatement ^ Resolve(System::Security::Policy::Evidence ^ evidence);

public System.Security.Policy.PolicyStatement Resolve (System.Security.Policy.Evidence evidence);

member this.Resolve : System.Security.Policy.Evidence -> System.Security.Policy.PolicyStatement

Public Function Resolve (evidence As Evidence) As PolicyStatement

매개 변수

evidence

Evidence

Evidence을 확인하는 데 사용되는 PolicyLevel입니다.

반환

PolicyStatement

결과 PolicyStatement입니다.

예외

PolicyException

정책 수준에 단독으로 표시된 여러 코드 그룹이 일치하는 경우

ArgumentNullException

evidence 매개 변수가 null인 경우

설명

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

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