StringCollection.cs

문자열 배열의 요소를 StringCollection의 끝에 복사합니다.

public:
 void AddRange(cli::array <System::String ^> ^ value);

public void AddRange (string[] value);

member this.AddRange : string[] -> unit

Public Sub AddRange (value As String())

매개 변수

value

String[]

StringCollection의 끝에 추가할 문자열의 배열입니다. 배열 자체는 null일 수가 없지만 null인 요소를 포함할 수 있습니다.

예외

ArgumentNullException

value이(가) null인 경우

예제

다음 코드 예제에서는 에 새 요소를 StringCollection추가합니다.

설명

StringCollection 는 null 유효한 값으로 허용되고 중복 요소를 허용합니다.

StringCollection 에서 용량을 늘리지 않고 새 요소를 수용할 수 있는 경우 이 메서드는 O(n) 작업이며 여기서 n 는 추가할 요소의 수입니다. 새 요소를 수용하기 위해 용량을 늘려야 하는 경우 이 메서드는 O(n + m) 작업이 됩니다. 여기서 n 는 추가할 요소의 수이고 m 는 입니다.Count
