StringCollection.CopyTo(String[], Int32) 메서드

정의

대상 배열의 지정한 인덱스에서 시작하여 전체 StringCollection 값을 1차원 문자열 배열에 복사합니다.Copies the entire StringCollection values to a one-dimensional array of strings, starting at the specified index of the target array.

public:
 void CopyTo(cli::array <System::String ^> ^ array, int index);
public void CopyTo (string[] array, int index);
member this.CopyTo : string[] * int -> unit
Public Sub CopyTo (array As String(), index As Integer)

매개 변수

array
String[]

StringCollection에서 복사된 요소의 대상인 1차원 문자열 배열입니다.The one-dimensional array of strings that is the destination of the elements copied from StringCollection. Array에는 0부터 시작하는 인덱스가 있어야 합니다.The Array must have zero-based indexing.

index
Int32

복사가 시작되는 array의 인덱스(0부터 시작)입니다.The zero-based index in array at which copying begins.

예외

arraynull인 경우array is null.

index가 0보다 작은 경우index is less than zero.

array가 다차원 배열인 경우array is multidimensional.

-또는--or- 소스 StringCollection의 요소 수가 대상 indexarray부터 끝까지 사용 가능한 공간보다 큽니다.The number of elements in the source StringCollection is greater than the available space from index to the end of the destination array.

소스 StringCollection의 형식을 대상 array의 형식으로 자동 캐스팅할 수 없습니다.The type of the source StringCollection cannot be cast automatically to the type of the destination array.

예제

다음 코드 예제에서는 StringCollection를 배열에 복사 합니다.The following code example copies a StringCollection to an array.

#using <System.dll>

using namespace System;
using namespace System::Collections;
using namespace System::Collections::Specialized;
void PrintValues( IEnumerable^ myCol );
int main()
{
   
   // Creates and initializes a new StringCollection.
   StringCollection^ myCol = gcnew StringCollection;
   array<String^>^myArr = {"RED","orange","yellow","RED","green","blue","RED","indigo","violet","RED"};
   myCol->AddRange( myArr );
   Console::WriteLine( "Initial contents of the StringCollection:" );
   PrintValues( myCol );
   
   // Copies the collection to a new array starting at index 0.
   array<String^>^myArr2 = gcnew array<String^>(myCol->Count);
   myCol->CopyTo( myArr2, 0 );
   Console::WriteLine( "The new array contains:" );
   for ( int i = 0; i < myArr2->Length; i++ )
   {
      Console::WriteLine( "   [{0}] {1}", i, myArr2[ i ] );

   }
   Console::WriteLine();
}

void PrintValues( IEnumerable^ myCol )
{
   IEnumerator^ myEnum = myCol->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      Object^ obj = safe_cast<Object^>(myEnum->Current);
      Console::WriteLine( "   {0}", obj );
   }

   Console::WriteLine();
}

설명

지정된 된 배열의 호환 되는 형식 이어야 합니다.The specified array must be of a compatible type.

요소는 StringCollection의 열거자가 StringCollection를 반복 하는 순서 대로 Array에 복사 됩니다.The elements are copied to the Array in the same order in which the enumerator of the StringCollection iterates through the StringCollection.

이 메서드는 O (n) 작업, 여기서 nCount합니다.This method is an O(n) operation, where n is Count.
