excel - 在文件夹中打开 Excel 工作簿以复制特定工作表时出现运行时错误 9

Question

我需要帮助来处理运行时错误 9。
我的目标是创建一个新工作簿，从文件夹中的所有 excel 工作簿中编译特定工作表(主用户)。
我在使用“on error goto”时被卡住了，因为我不知道如何在错误(工作表不存在)转到下一个工作簿时设置程序。
我的代码现在导致我在没有“主用户”工作表的工作簿上陷入永无止境的循环

Sub Master()
    Dim MyFiles As String
    Dim Path As String
    Dim myExtension As String
    Dim Filename As String
    
    Workbooks.Add.SaveAs Filename:="Master", FileFormat:=51
    Path = "D:\My Document\"
    myExtension = "*.xls*"
    MyFiles = Dir(Path & myExtension)
    
    On Error GoTo test

DoAgain:
    Do While MyFiles <> ""
    Workbooks.Open (Path & MyFiles)
      Sheets("master user").Select
      ActiveSheet.Rows(1).Copy
      Workbooks("Master.xlsx").Activate
      Sheets.Add After:=Sheets(Sheets.Count)
      Range("A1").PasteSpecial xlPasteAll
      If InStr(MyFiles, ".") > 0 Then
   Filename = Left(MyFiles, InStr(MyFiles, ".") - 1)
End If
      ActiveSheet.Name = Filename
      Workbooks(Filename).Activate
      Application.CutCopyMode = False
      ActiveWorkbook.Close SaveChanges:=False
    MyFiles = Dir
    Loop
      Workbooks("Master.xlsx").Activate
      ActiveWorkbook.Close SaveChanges:=True

test:
      ActiveWorkbook.Close SaveChanges:=False
Resume DoAgain

ActiveWorkbook.Save
End Sub

将工作表范围从多个工作簿复制到新工作簿
工作簿

包含此代码的工作簿 (ThisWorkbook)。

源工作簿，即在源文件夹中找到的每个工作簿(文件)。

目标工作簿，即将复制到的新添加的工作簿。

说明

这会将文件夹中找到的每个工作簿(文件)的同名工作表的第一行复制到新工作簿(一个)的新添加(和重命名)工作表(多个)。
