vba - 如何获取 WorksheetFunction.SumProduct() 值以匹配 =SUMPRODUCT()？

Question

我正在尝试使用 SUMPRODUCT 来确定一个范围内的所有非空白值是否相同。我能够使用 this answer 将其作为 Excel 公式工作。 ，现在我想通过使用 WorksheetFunction.SumProduct() 在 VBA 中获得结果.

我尝试了以下方法:

Public Function onlyOneValue(sheet As Worksheet) As Boolean

Dim sumProduct As Variant
Dim rng As Range
Dim rngAddress As String
Dim sumProductString As String
Dim column As Long

    Set rng = sheet.Range(sheet.Cells(5,20), _
                        sheet.Cells(65,20))
    rngAddress = rng.address
    sumProductString = "(" & rngAddress & "<>"""")/countif(" & _
                                            rngAddress & "," & rngAddress & "&"""")"
    sumProduct = WorksheetFunction.sumProduct(Evaluate(sumProductString))
    onlyOneValue = sumProduct = 1
End If

End Function

当我使用所有非空白值都相同的列进行测试时， sumProduct 的值是 1.63934426229508E-02 ，但是当我复制 sumProductString变成 =SUMPRODUCT()工作表上的公式，我得到 1 的期望值.

如果我不使用 Evaluate()而是使用:

WorksheetFunction.sumProduct(sumProductString)

然后我得到这个错误:

Unable to get the SumProduct property of the WorksheetFunction class

如何在 VBA 中实现此功能？

Answer 1

当我添加 SUMPRODUCT 时，它对我有用进入Evaluate并调整(即:

Public Function onlyOneValue(sheet As Worksheet) As Boolean

Dim rng As Range
Dim rngAddress As String
Dim sumProductString As String

    Set rng = sheet.Range(sheet.Cells(5, 20), _
                        sheet.Cells(65, 20))
    rngAddress = rng.Address
    sumProductString = "=SUMPRODUCT((" & rngAddress & "<>"""")/countif(" & _
                                            rngAddress & "," & rngAddress & "&""""))"

    onlyOneValue = (CLng(Evaluate(sumProductString)) = 1)

End Function
