요소가 지정된 값의 복사본인 ArrayList를 반환합니다.

public:
 static System::Collections::ArrayList ^ Repeat(System::Object ^ value, int count);

public static System.Collections.ArrayList Repeat (object value, int count);

public static System.Collections.ArrayList Repeat (object? value, int count);

static member Repeat : obj * int -> System.Collections.ArrayList

Public Shared Function Repeat (value As Object, count As Integer) As ArrayList

매개 변수

value

Object

새 ArrayList에서 여러 번 복사할 Object입니다. 값은 null이 될 수 있습니다.

count

Int32

value이(가) 복사되어야 하는 횟수입니다.

반환

ArrayList

모두 value의 복사본에 해당하는 count개의 요소가 포함된 ArrayList입니다.

예외

ArgumentOutOfRangeException

count가 0보다 작은 경우

예제

다음 코드 예제에서는 동일한 값으로 새로 ArrayList 만들고 초기화하는 방법을 보여줍니다.

설명

ArrayList 는 null 유효한 값으로 허용되고 중복 요소를 허용합니다.

이 메서드는 O(n) 작업입니다 n count.
