ArrayList의 지정된 인덱스에 컬렉션의 요소를 삽입합니다.
public:
virtual void InsertRange(int index, System::Collections::ICollection ^ c);
public virtual void InsertRange (int index, System.Collections.ICollection c);
abstract member InsertRange : int * System.Collections.ICollection -> unit
override this.InsertRange : int * System.Collections.ICollection -> unit
Public Overridable Sub InsertRange (index As Integer, c As ICollection)
매개 변수
- index
- Int32
새 요소가 삽입되어야 하는 0부터 시작하는 인덱스입니다.
요소가 ICollection에 삽입되어야 하는 ArrayList입니다. 컬렉션 자체가 null
일 수는 없지만 null
인 요소를 포함할 수는 있습니다.
예외
c
이(가) null
인 경우

설명
ArrayList 는 null
유효한 값으로 허용되고 중복 요소를 허용합니다.
새 Count (컬렉션의 현재 Count 더하기 크기)가 보다 Capacity크면 새 요소를 수용하도록 내부 배열을 자동으로 재할당하여 의 ArrayList 용량이 증가하고 새 요소가 추가되기 전에 기존 요소가 새 배열에 복사됩니다.
가 과 같Count으면 index
요소가 의 ArrayList끝에 추가됩니다.
의 요소 순서는 에 ICollectionArrayList유지됩니다.
목록처럼 연속된 요소로 구성된 컬렉션에서는 삽입 지점 다음에 있는 요소를 아래로 이동하여 새 요소로 적용합니다. 컬렉션에 인덱스가 지정된 경우 이동되는 요소의 인덱스도 업데이트됩니다. 요소가 해시 테이블 같은 버킷으로 개념적으로 그룹화되어 있는 컬렉션에는 이러한 동작이 적용되지 않습니다.
이 메서드는 연산입니다 O(n + m)
. 여기서 n
는 추가할 요소의 수이고 m
는 입니다 Count.
