속성 값
HRESULT 값입니다.
설명
HRESULT는 32 비트 값이며 심각도 코드, 기능 코드, 오류 코드의 세 가지 다른 필드로 나누어집니다. 심각도 코드는 반환 값이 정보, 경고 또는 오류를 표시하는지 여부를 나타냅니다. 기능 코드는 오류를 담당하는 시스템의 영역을 식별합니다. 오류 코드는 예외를 표시하기 위해 할당되는 고유한 숫자입니다. 각각의 예외는 고유한 HRESULT에 매핑됩니다. 관리 코드가 예외를 throw할 때, 공용 언어 런타임은 HRESULT를 COM 클라이언트에 전달합니다. 비관리 코드가 오류를 반환하면, HRESULT는 예외로 전환되고 공용 언어 런타임에 의해 throw됩니다.
예제
다음 코드 예제에서는 HResult 속성을 생성자에 설정하는 파생 Exception 클래스를 정의합니다.
