VBA 计算数组的最大索引和最小索引

计算数据的最大索引和最小索引分别用 Ubound 和 LBound 函数。对于多维索引需要指定数据的目标维度。

1、一维数组

Sub arr_idx_cnt()
    Dim arr(23 To 72)      '定义数组
    Static min_idx, max_idx, n As Integer, msg As String            '声明本地变量
    min_idx = LBound(arr)
    max_idx = UBound(arr)
    n = max_idx - min_idx + 1
    msg = "数组的最小索引号是:" & min_idx & Chr(13) _
           & "数组的最大索引号是:" & max_idx & Chr(13) _
           & "数组的元素个数是:" & n
    MsgBox msg
End Sub

 2、多维数组

Sub arr_idx_cnt()
    Dim arr(23, 72)      '定义二维数组
    Static min_idx_a, max_idx_b, n As Integer, msg As String        '声明本地变量
    min_idx_a = LBound(arr, 1)
    max_idx_b = UBound(arr, 2)
    msg = "数组第一维度的最小索引号是:" & min_idx_a & Chr(13) & _
          "数组第二维度的最大索引号是:" & max_idx_b
    MsgBox msg
End Sub
