Question

目前，当我的文件只在名为“E：\ Dian \ Test”的主文件夹中时，我的代码运行良好。（只读取在主文件夹（MyPath）中复制的文件，但不读取子文件夹中的文件）

我的问题是如何更改/添加现有代码以包含一个循环，以包括在E：\ Dian \ Test文件夹中搜索SubFolders，以.xlsx文件开头，名称为“out _ *”

请记住我的编程技巧不是很好。

谢谢：）

Answer 1

对于这类问题，我使用了命令外壳。您可以使用PowerShell，但我还没有开发代码。

这是一个简短的例程，它将名称中具有特定模式的所有文件放入数组vFileList中。然后，您可以遍历该数组。

请注意，shell dir命令使用\S和\B开关。

\ S表示读取此文件夹和所有子文件夹中的项目 \ B删除所有无关的信息，只留下完整的文件路径

在您的情况下，您可能会设置

MyPath = "E:\Dian\Test\out_*.xlsx"



Option Explicit
'set reference to Windows Script Host Object Model
Sub GetFiles()
    Const myPath As String = "D:\Users\Ron\b*.xlsx"
    Dim WSH As WshShell
    Dim vFileList As Variant
Set WSH = New WshShell
vFileList = Split(WSH.Exec("CMD /c dir """ & myPath & """/B /S").StdOut.ReadAll, vbLf)
End Sub
