Type.IsArrayImpl 메서드
파생 클래스에서 재정의된 경우, IsArray 속성을 구현하고 Type이 배열인지 여부를 확인합니다.
네임스페이스: System
어셈블리: mscorlib(mscorlib.dll)
구문
‘선언
Protected MustOverride Function IsArrayImpl As Boolean
‘사용 방법
Dim returnValue As Boolean
returnValue = Me.IsArrayImpl
protected abstract bool IsArrayImpl ()
protected:
virtual bool IsArrayImpl () abstract
protected abstract boolean IsArrayImpl ()
protected abstract function IsArrayImpl () : boolean
반환 값
Type이 배열이면 true이고, 그렇지 않으면 false입니다.
설명
Array 클래스의 인스턴스는 배열이 아니라 개체이므로 false가 반환되어야 합니다.
예제
다음 예제에서는 MyTypeDelegator 클래스에서 IsArrayImpl 메서드를 재정의하고 변수가 배열인지 확인하여 결과를 표시합니다.
