Excel VBA在PDF的单独页面中打印多个命名范围

Question

I have list of named ranges and each range I set it to suit single page. I use following code to export into PDF, where It get merged together into single page.

Dim wbBook As Workbook
Dim i As Integer
Dim rs As Range

Set wbBook = ActiveWorkbook
Set rs = wbBook.Names(1).RefersToRange
For i = 2 To wbBook.Names.Count
   Set rs = Union(rs, wbBook.Names(i).RefersToRange)
Next

rs.ExportAsFixedFormat xlTypePDF, strPath, , , False

But below code works for me, when I enter range name manually. Whereas my named range are dynamic. I think, above code needs some modification to work. Will anyone assist me to get this done?

Set rs = wbBook.Range("Page_1,Page_2,Page_3")
rs.Select
Selection.ExportAsFixedFormat xlTypePDF, strPath, , , False

Proposed solution still give one page. I provided below the page setup, Is something wrong with page setup ?

With Sheet1.PageSetup
.PrintArea = Range(Cells(iBeginRow, 1), Cells(iRow + 2, 5)).Address
.CenterHorizontally = True
.CenterVertically = True
.Orientation = xlLandscape
.LeftMargin = Application.InchesToPoints(0)
.RightMargin = Application.InchesToPoints(0)
.TopMargin = Application.InchesToPoints(0)
.BottomMargin = Application.InchesToPoints(0)
.HeaderMargin = Application.InchesToPoints(0)
.FooterMargin = Application.InchesToPoints(0)
.PrintQuality = 600
.FitToPagesWide = 1
.FitToPagesTall = 1
End With

Then I dynamically name the range

Sheet1.Range(Cells(iBeginRow, 1), Cells(iRow + 2, 5)).Select
Selection.Name = "Page_" & PageNum

Below UDF worked for me (I had it in a module):

Sub ExportRangeToPDF(ByVal WSName As String)

    Dim oRng As Range
    Dim strPath As String: strPath = "C:\temp\Temp\"
    Dim intCount As Integer

    For intCount = 1 To ActiveWorkbook.Names.Count

        If InStr(1, LCase(ActiveWorkbook.Names(intCount).RefersToRange.Name.Name), LCase(WSName)) > 0 Then

            If oRng Is Nothing Then
                Set oRng = Range(ActiveWorkbook.Names(intCount).RefersToRange.Name.Name)
            Else
                Set oRng = Union(oRng, Range(ActiveWorkbook.Names(intCount).RefersToRange.Name.Name))
            End If

        End If

    Next

    oRng.ExportAsFixedFormat xlTypePDF, strPath & "test.pdf", , , False

    Set oRng = Nothing

End Sub

NOTE : I had some 'solver' and 'filterdatabase' ranges in the workbook I was working on so had to add some validation for those before it worked. If you have any such ranges in your workbook, you might have to do the same
