설명
시스템에서 해당 요소를 배열에 대해 선언된 형식으로 변환할 수 없으면 ArrayTypeMismatchException이 throw됩니다. 예를 들어, String 형식의 요소를 Int32 배열에 저장할 수 없습니다. 이는 두 형식 사이의 변환이 지원되지 않기 때문입니다. 일반적으로 응용 프로그램에서는 이 예외를 throw할 필요는 없습니다.
다음 MSIL(Microsoft Intermediate Language) 명령은 ArrayTypeMismatchException을 throw합니다.
ldelem.<type>
ldelema
stelem.<type>
ArrayTypeMismatchException은 0x80131503 값을 가지는 HRESULT COR_E_ARRAYTYPEMISMATCH를 사용합니다.
ArrayTypeMismatchException 인스턴스의 초기 속성 값 목록에 대한 자세한 내용은 ArrayTypeMismatchException 생성자를 참조하십시오.
