Visual Basic - 编译错误：无效的限定符

Question

我在Visual Basic中编写自定义Excel函数。当我运行该函数时，我在行Compile error: Invalid qualifier上的mondayArray上收到错误：For index = 0 To mondayArray.Length - 1。导致此错误的原因是什么？

Function SumHours(monday, tuesday, wednesday, thursday, friday, saturday, sunday)
    Dim mondayHours As Integer

    Dim mondayArray() As String
    Dim splitArray() As String

    SumHours = 0

    If monday <> "/" Then
        mondayArray = Split(monday, " ")

        For index = 0 To mondayArray.Length - 1
            splitArray = Split(mondayArray(index), "-")
        Next

    End If
End Function

Answer 1

.length不是数组的属性。使用LBound function和UBound function确定数组的范围（下边界和上边界）。

        For index = LBound(mondayArray) To UBound(mondayArray)

我相信你混淆了集合中的.length属性;例如HtmlElementCollection。
