Visual Basic.NET 引用 Excel 的 Range 的数组的下限值冲突

Module Module1
    Sub main()
        Const fsiFilePath = "C:\测试.xlsx"
        Const ExportedRange As String = "B9:B17"

        Dim Wksht As Worksheet
        Wksht = iWkbk.Worksheets(1)
        Dim DataInRange(,) As Object
        DataInRange = Wksht.Range(ExportedRange).Value   
        '从下图中可以看出来，DataInRange是从(0,0)到(8,0)的数组。
        Debug.Print(LBound(DataInRange))    '返回值为1
        Debug.Print(UBound(DataInRange))    '返回值为9
        Dim a1 As Single = DataInRange(1, 1)   '返回局部列表中(0,0)位置的值
        Dim a2 = DataInRange(0, 0)           '报错：索引超出了数组界限
        iWkbk.Close()
        ExcelApp.Quit()
