이 메서드가 추상 메서드인지 여부를 나타내는 값을 가져옵니다.

public:
 property bool IsAbstract { bool get(); };

public bool IsAbstract { get; }

member this.IsAbstract : bool

Public ReadOnly Property IsAbstract As Boolean

속성 값

Boolean

해당 메서드가 추상 메서드이면 true이고, 그렇지 않으면 false입니다.

구현

IsAbstract

예제

다음 예제에서는 지정된 메서드가 추상인지 여부를 확인하고 결과를 표시합니다.

설명

추상 멤버는 기본 클래스에 선언되며 제공된 구현이 없습니다.

를 얻으려면 MethodBase먼저 형식을 가져옵니다. 형식에서 메서드를 가져옵니다. 메서드 MethodBase에서 . MethodBase 또는 생성자가 public이 아닌 경우 보호되며 쉽게 액세스할 수 없습니다. public이 아닌 메서드에 액세스하려면 마스크 NonPublic 를 BindingFlags로 GetMethod설정합니다.
