반환 값
Array의 단순 복사본입니다.
설명
Array의 단순 복사본은 참조 형식 또는 값 형식에 관계 없이 Array의 요소만을 복사하지만 참조에서 참조하는 개체는 복사하지 않습니다. 새 Array의 참조는 원래 Array의 참조에서 가리키는 개체와 동일한 개체를 가리킵니다.
이와 반대로 Array의 전체 복사본은 요소와 해당 요소가 직접 또는 간접적으로 참조하는 모든 대상을 복사합니다.
복제본은 원래 Array와 동일한 Type으로 되어 있습니다.
이 메서드는 O(n) 연산이며, 여기서 n은 Length입니다.
예제
다음 코드 예제에서는 System.Globalization.CultureInfo 배열을 복제하고 단순 복사본의 동작을 보여 줍니다.
