Array.GetLowerBound 메서드
Array에 있는 지정한 차원의 하한을 가져옵니다.
네임스페이스: System
어셈블리: mscorlib(mscorlib.dll)
구문
‘선언
Public Function GetLowerBound ( _
dimension As Integer _
) As Integer
‘사용 방법
Dim instance As Array
Dim dimension As Integer
Dim returnValue As Integer
returnValue = instance.GetLowerBound(dimension)
public int GetLowerBound (
int dimension
)
public:
int GetLowerBound (
int dimension
)
public int GetLowerBound (
int dimension
)
public function GetLowerBound (
dimension : int
) : int
매개 변수
- dimension
하한을 지정해야 하는 Array의 0부터 시작하는 차원입니다.
반환 값
Array에 있는 지정한 차원의 하한입니다.
예외
| 예외 형식 | 조건 |
|---|---|
dimension이 0보다 작은 경우 - 또는 - dimension이 Rank보다 크거나 같은 경우 |
설명
GetLowerBound(0)는 Array의 첫 번째 차원의 인덱스에 대한 하한을 반환하고 GetLowerBound(Rank - 1)는 Array의 마지막 차원의 하한을 반환합니다.
이 메서드는 O(1) 연산입니다.
예제
다음 코드 예제에서는 GetLowerBound 및 GetUpperBound를 사용하여 1차원 배열과 다차원 배열을 초기화합니다.
