Array.GetUpperBound(Int32) 메서드

정의

배열에서 지정된 차원의 마지막 요소의 인덱스를 가져옵니다.

public:
 int GetUpperBound(int dimension);
public int GetUpperBound (int dimension);
member this.GetUpperBound : int -> int
Public Function GetUpperBound (dimension As Integer) As Integer

매개 변수

dimension
Int32

상한을 지정해야 하는 배열의 0부터 시작하는 차원입니다.

반환

Int32

배열에 있는 지정된 차원의 마지막 요소의 인덱스이거나 지정된 차원이 비어 있는 경우 -1입니다.

예외

dimension가 0보다 작은 경우

또는

dimensionRank보다 크거나 같은 경우

예제

다음 예제에서는 및 GetUpperBound 메서드를 사용하여 GetLowerBound 1차원 및 2차원 배열의 경계를 표시하고 해당 배열 요소의 값을 표시합니다.

설명

GetUpperBound(0) 는 배열의 첫 번째 차원에 있는 마지막 인덱스와 배열 GetUpperBound(Rank - 1) 의 마지막 차원의 마지막 인덱스 값을 반환합니다.

이 방법은 O(1) 작업에 설명 합니다.
