【问题描述】：

我遇到了以下问题：工作簿包含一个名为“名称”的工作表。它有姓名和姓氏、eng 姓名、rus 姓名和员工性别以及代码的列。代码应该从列中获取值，然后它创建一个数组并循环遍历这些数组，它应该相应地更改另一张表上的值，例如员工 1、员工 1 的姓名、...员工 1 的代码, 员工 2, 员工 2 的姓名, ... 员工 2 的代码，但它的执行方式如下：员工 1，员工 1 的姓名，... 员工 1 的代码，员工 1，员工 1 的姓名，... . 员工 2 的代码，员工 1，员工 1 的姓名，... 员工 3 的代码等等。很明显，我丢失了应该以假定方式生成的代码，但我找不到它。

代码如下。非常感谢您！

Sub SaveAsPDF()

Dim ws As Workbook
Dim nm As Worksheet
Dim last_row As Long
Dim names_surname, name, sex, promocode As Variant
Dim Certificate As Worksheet
Dim FilePath As String

Set ws = ThisWorkbook
Set nm = ws.Sheets("Names")

With nm
    last_row = .Range("A1").CurrentRegion.Rows.Count
    names_surname = Application.Transpose(nm.Range("E2:E" & last_row).Value2)
    name = Application.Transpose(.Range("F2:F" & last_row).Value2)
    sex = Application.Transpose(.Range("G2:G" & last_row).Value2)
    promocode = Application.Transpose(.Range("H2:H" & last_row).Value2)
End With

Set Certificate = ws.Sheets("Certificate_PDF")
FilePath = "C:\Users\name\folder\2021\Desktop\Certificates"

For Each ns In names_surname
    For Each n In name
        For Each s In sex
            For Each p In promocode
                If s = "mr" Then
                    Certificate.Range("Name").Value = "Dear, " & n & "!"
                Else
                    Certificate.Range("Name").Value = "Dear, " & n & "!"
                End If
                    Certificate.Range("Promo").Value = "Code: " & p
                    Certificate.PageSetup.Orientation = xlPortrait
                    Certificate.ExportAsFixedFormat Type:=xlTypePDF, FileName:=FilePath & "\" & ns & ".pdf", Quality:=xlQualityStandard, IncludeDocProperties:=True, IgnorePrintAreas:=False

                Next p
            Next s
        Next n
    Next ns

MsgBox "Completed", vbInformation

End Sub

【参考方案1】：

不要嵌套循环，只循环一个二维数组。

Option Explicit
Sub SaveAsPDF()

    Dim wb As Workbook
    Dim wsNm As Worksheet, wsCert As Worksheet
    Dim last_row As Long
    Dim ar As Variant
    Dim FilePath As String
    
    Set wb = ThisWorkbook
    Set wsNm = wb.Sheets("Names")
    With wsNm
        last_row = .Cells(.Rows.Count, "E").End(xlUp).Row
        ar = .Range("E2:H" & last_row).Value2
    End With
    
    Set wsCert = wb.Sheets("Certificate_PDF")
    FilePath = wb.Path '"C:\Users\name\folder\2021\Desktop\Certificates"
    
    Dim i As Long, fullname As String, name As String, sex As String, promocode As String
    For i = 1 To UBound(ar)
        fullname = ar(i, 1) ' E name surname
        name = ar(i, 2) ' F
        sex = ar(i, 3) ' G
        promocode = ar(i, 4) 'H
        
        With wsCert
            If sex = "mr" Then
                .Range("Name").Value = "Dear, " & name & "!"
            Else
                .Range("Name").Value = "Dear, " & name & "!"
            End If
            .Range("Promo").Value = "Code: " & promocode
            
            ' export as pdf
            .PageSetup.Orientation = xlPortrait
            .ExportAsFixedFormat Type:=xlTypePDF, _
            Filename:=FilePath & "\" & fullname & ".pdf", _
