PropertyAttributes 열거형

아티클
08/21/2007

속성과 관련될 수 있는 특성을 정의합니다. 이러한 특성 값은 corhdr.h에 정의되어 있습니다.

이 열거형에는 멤버 값를 비트로 조합할 수 있는 FlagsAttribute 특성이 있습니다.

멤버

	멤버 이름	설명
	HasDefault	속성이 기본값을 갖도록 지정합니다.
	None	속성과 관련된 특성이 없도록 지정합니다.
	Reserved2	예약되었습니다.
	Reserved3	예약되었습니다.
	Reserved4	예약되었습니다.
	ReservedMask	런타임 전용으로 예약된 플래그를 지정합니다.
	RTSpecialName	메타데이터 내부 API에서 이름 인코딩을 확인하도록 지정합니다.
	SpecialName	속성의 특수성을 설명하는 이름을 사용하여 속성을 지정합니다.

설명

PropertyAttributes를 가져오려면 먼저 Type 클래스를 가져옵니다. Type에서 PropertyInfo를 가져옵니다. PropertyInfo에서 Attributes를 가져옵니다.

열거형 값은 메서드에 구현된 특성의 비트 OR를 나타내는 숫자입니다.

예제

다음 예제에서는 세 개의 속성을 작성하고 PropertyAttributes 열거형 값을 표시합니다. 읽기 전용 속성에는 setter가 없으므로 Caption = statement를 사용하여 변경할 수 없습니다.
