我在 VBA 中的函数中编写了一些代码，但我一直坚持如何在 if - else 语句中返回输出值 areaAnswer1 和 areaAnswer2。我还是新手。非常感谢任何帮助和建议。
Function dateArea(inputDate1 As Date, t1 As Date, t2 As Date, duration As Integer, output As Integer) As Integer
endOfYear = Workbook.Date(Year(inputDate1), 12, 31)
inputDate2 = Workbook.Date(Year(inputDate1) + 1, Month(inputDate1), Day(inputDate1))
endOfDate1 = Workbook.Date(Year(inputDate1) + duration, Month(inputDate1), Day(inputDate1))
endOfDate2 = Workbook.Date(Year(inputDate2) + duration, Month(inputDate2), Day(inputDate2))
areaBase1 = endOfYear - inputDate1
areaBase2 = inputDate2 - endOfYear
totalArea1 = areaBase1 * 365
totalArea2 = areaBase2 * 365
triangleBase1 = endOfDate1 - inputDate1
triangleHypo1 = Workbook.Sqrt((365 * 365) + (triangleBase1 * triangleBase1))
triangleBase2 = t1 - inputDate2
triangleHypo2 = triangleHypo1 * triangleBase2 / triangleBase1
triangleHeight2 = Workbook.Sqrt((triangleHypo2 * triangleHypo2) - (triangleBase2 * triangleBase2))
triangleArea2 = (triangleBase2 * triangleHeight2) / 2
triangleBase3 = (inputDate2 - endOfYear) + (t1 - inputDate2)
triangleHypo3 = triangleBase3 * triangleHypo2 / (t1 - inputDate2)
triangleHeight3 = Workbook.Sqrt((triangleHypo3 * triangleHypo3) - (triangleBase3 * triangleBase3))
triangleArea3 = (triangleBase3 * triangleBaseHeight3) / 2
areaDiffBot2 = triangleArea3 - triangleArea2
triangleBase4 = 365 + (t1 - inputDate2)
triangleHypo4 = triangleBase4 * triangleHeight2 / (t1 - inputDate2)
triangleHeight4 = Workbook.Sqrt((triangleHypo4 * triangleHypo4) - (triangleBase4 * triangleBase4))
triangleArea4 = (triangleBase4 * triangleHeight4) / 2
areaDiffBot1 = triangleArea4 - triangleArea3
triangleHeight5 = 365 * (endOfDate1 - t2) / triangleBase1
triangleHypo5 = Workbook.Sqrt((triangleHeight5 * triangleHeight5) + ((endOfDate1 - t2) * (endOfDate1 - t2)))
triangleArea5 = (endOfDate1 - t2) * triangleHeight5 / 2
triangleBase6 = (endOfDate1 - t2) + areaBase1
triangleHeight6 = (triangleBase6) * 365 / (endOfDate1 - t2)
triangleHypo6 = Workbook.Sqrt((triangleBase6 * triangleBase6) + (triangleHeight6 * triangleHeight6))
triangleArea6 = (triangleBase6 * triangleHeight6) / 2
areaDiffTop1 = triangleArea6 - triangleArea5
triangleBase7 = triangleBase6 + areaBase2
triangleHeight7 = triangleBase7 * triangleHeight6 / triangleBase6
triangleHypo7 = Workbook.Sqrt((triangleBase7 * triangleBase7) + (triangleHeight7 * triangleHeight7))
triangleArea7 = (triangleBase7 * triangleHeight7) / 2
areaDiffTop2 = triangleArea7 - triangleArea6
totalUsedArea1 = areaDiffTop1 + areaDiffBot1
totalUsedArea2 = areaDiffTop2 + areaDiffBot2
areaAnswer1 = totalArea1 - totalUsedArea1
areaAnswer2 = totalArea2 - totalUsedArea2
If output = 1 Then
ElseIf output = 2 Then
ElseIf output = 3 Then
Else
End If
End Function
最佳答案
在 VBA 中，您通过将返回值分配给如下函数来设置返回值:
areaAnswer1 = totalArea1 - totalUsedArea1
areaAnswer2 = totalArea2 - totalUsedArea2
If output = 1 Then
dateArea = areaAnswer1
ElseIf output = 2 Then
dateArea = areaAnswer2
ElseIf output = 3 Then
' ...etc
请注意，对函数的赋值不会退出函数。在这种情况下，您不需要立即退出，因为您已经结束了。但在某些情况下，您希望在分配返回值后立即退出该函数:
Exit Function
