대상 배열의 지정된 인덱스에서 시작하여 전체 BitArray을 호환되는 1차원 Array에 복사합니다.

public:
 virtual void CopyTo(Array ^ array, int index);

public void CopyTo (Array array, int index);

abstract member CopyTo : Array * int -> unit
override this.CopyTo : Array * int -> unit

Public Sub CopyTo (array As Array, index As Integer)

매개 변수

array: Array

Array에서 복사한 요소의 대상인 일차원 BitArray입니다. Array에는 0부터 시작하는 인덱스가 있어야 합니다.

index: Int32

array에서 복사가 시작되는 0부터 시작하는 인덱스입니다.

구현

CopyTo(Array, Int32)

예외

ArgumentNullException

array이(가) null인 경우

ArgumentOutOfRangeException

index가 0보다 작은 경우

ArgumentException

array가 다차원 배열인 경우

또는

소스 BitArray의 요소 수가 대상 array의 index부터 끝까지 사용 가능한 공간보다 큽니다.

InvalidCastException

소스 BitArray의 형식을 대상 array의 형식으로 자동 캐스팅할 수 없습니다.
