ArrayList.SetRange(Int32, ICollection) 메서드

정의

네임스페이스:

System.Collections

어셈블리:

System.Runtime.dll

Source:

ArrayList.cs

ArrayList의 요소 범위에 대해 컬렉션의 요소를 복사합니다.

public:
 virtual void SetRange(int index, System::Collections::ICollection ^ c);

public virtual void SetRange (int index, System.Collections.ICollection c);

abstract member SetRange : int * System.Collections.ICollection -> unit
override this.SetRange : int * System.Collections.ICollection -> unit

Public Overridable Sub SetRange (index As Integer, c As ICollection)

매개 변수

index

Int32

c의 요소 복사를 시작할 0부터 시작하는 ArrayList 인덱스입니다.

c

ICollection

ArrayList에 요소를 복사할 ICollection입니다. 컬렉션 자체가 null일 수는 없지만 null인 요소를 포함할 수는 있습니다.

예외

ArgumentOutOfRangeException

index가 0보다 작은 경우

또는

index + c의 요소 수가 Count보다 큽니다.

ArgumentNullException

c이(가) null인 경우

NotSupportedException

ArrayList이 읽기 전용인 경우

예제

다음 코드 예제에서는 설정 하 고 에서 요소의 범위를 가져오는 방법을 보여 주는 ArrayList합니다.

설명

ArrayList 는 null 유효한 값으로 허용되고 중복 요소를 허용합니다.

의 요소 순서는 에 ICollectionArrayList유지됩니다.

이 메서드는 작업입니다 O(n) . 여기서 n 는 입니다 Count.
