HybridDictionary.CopyTo(Array, Int32) 메서드

정의

지정한 인덱스에서 HybridDictionary 엔트리를 1차원 Array 인스턴스에 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 DictionaryEntry 개체의 대상인 1차원 HybridDictionary 배열입니다. Array에는 0부터 시작하는 인덱스가 있어야 합니다.

index
Int32

array에서 복사가 시작되는 0부터 시작하는 인덱스입니다.

구현

예외

array이(가) null인 경우

index가 0보다 작은 경우

array가 다차원 배열인 경우

또는

소스 HybridDictionary의 요소 수가 대상 arrayarrayIndex부터 끝까지 사용 가능한 공간보다 큽니다.

소스 HybridDictionary의 형식을 대상 array의 형식으로 자동 캐스팅할 수 없습니다.

예제

다음 코드 예제에서는 의 요소를 HybridDictionary 배열에 복사합니다.

설명

요소는 열거자가 를 반복하는 순서와 동일한 순서로 에 복사 Array 됩니다 HybridDictionary.

의 키만 복사하려면 를 HybridDictionary사용합니다 HybridDictionary.Keys.CopyTo.

의 값만 복사하려면 를 HybridDictionary사용합니다 HybridDictionary.Values.CopyTo.

이 메서드는 O (n) 작업, 여기서 nCount합니다.
