ArrayList의 끝에 ICollection의 요소를 복사합니다.

네임스페이스: System.Collections
어셈블리: mscorlib(mscorlib.dll)

구문

‘선언
Public Overridable Sub AddRange ( _
    c As ICollection _
)
‘사용 방법
Dim instance As ArrayList
Dim c As ICollection

instance.AddRange(c)

public virtual void AddRange (
    ICollection c
)

public:
virtual void AddRange (
    ICollection^ c
)

public void AddRange (
    ICollection c
)

public function AddRange (
    c : ICollection
)

매개 변수

c
요소가 ArrayList의 끝에 추가되어야 하는 ICollection입니다. 컬렉션 자체가 Null 참조(Visual Basic의 경우 Nothing)일 수는 없지만 Null 참조(Visual Basic의 경우 Nothing)인 요소를 포함할 수는 있습니다.

예외

예외 형식	조건
ArgumentNullException	c가 Null 참조(Visual Basic의 경우 Nothing)인 경우
NotSupportedException	ArrayList가 읽기 전용인 경우 - 또는 - ArrayList의 크기가 고정되어 있는 경우

ArgumentNullException

c가 Null 참조(Visual Basic의 경우 Nothing)인 경우

NotSupportedException

ArrayList가 읽기 전용인 경우

- 또는 -

ArrayList의 크기가 고정되어 있는 경우

설명

ArrayList은 Null 참조(Visual Basic의 경우 Nothing)을 유효한 값으로 받아들이며 중복 요소를 허용합니다.

ICollection의 요소 순서는 ArrayList에서 유지됩니다.

새 Count(현재 Count에 컬렉션의 크기를 더한 값)가 Capacity보다 크면 ArrayList의 용량이 새 요소를 수용하기 위해 내부 배열을 자동으로 재할당하여 증가하며 기존 요소가 새 배열로 복사된 후 새 요소가 추가됩니다.

ArrayList가 Capacity를 증가시키지 않고 새 요소를 수용할 수 있으면 이 메서드는 O(n) 연산이 됩니다. 여기에서 n은 추가될 요소의 수입니다. 용량을 증가시켜 새 요소를 수용해야 하는 경우 이 메서드는 O(n + m) 연산이 됩니다. 여기에서 n은 추가될 요소의 수이고 m은 Count를 나타냅니다.

다음 코드 예제에서는 ArrayList에 요소를 추가하는 방법을 보여 줍니다.
