获取VBA中的子目录列表

Question

获取VBA中的子目录列表

Mat*_*ech 20 recursion vba ms-word ms-office word-vba

我想获得目录中所有子目录的列表.
如果可行,我想将其扩展为递归函数.

然而,我最初获得子目录的方法失败了.它只显示包括文件在内的一切:

sDir = Dir(sPath, vbDirectory)
Do Until LenB(sDir) = 0
    Debug.Print sDir
    sDir = Dir
Loop

该列表以".."和几个文件夹开头,以".txt"文件结尾.

编辑:
我应该补充说,这必须在Word中运行,而不是Excel(许多功能在Word中不可用),它是Office 2010.

编辑2:

可以使用确定结果的类型

iAtt = GetAttr(sPath & sDir)
If CBool(iAtt And vbDirectory) Then
   ...
End If

但这给了我新的问题,所以我现在正在使用基于的代码Scripting.FileSystemObject.

2014年7月更新:添加了PowerShell选项并删除了第二个代码,仅列出文件夹

以下方法运行完全递归过程而不是FileSearch在Office 2007中弃用.(后两个代码仅使用Excel进行输出 - 可以删除此输出以便在Word中运行)

贝壳 PowerShell
使用FSO与Dir用于过滤的文件类型.来自EE支付墙背后的EE 答案.这比你要求的(文件夹列表)要长,但我认为它很有用,因为它为你提供了一系列结果以便进一步使用
用Dir.这个例子来自我在另一个网站上提供的答案

使用FileSystemObject会更好.我认为.

要打电话给你,你需要说:listfolders"c:\ data"

Sub listfolders(startfolder)
''Reference Windows Script Host Object Model
''If you prefer, just Dim everything as Object
''and use CreateObject("Scripting.FileSystemObject")
Dim fs As New FileSystemObject
Dim fl1 As Folder
Dim fl2 As Folder

Set fl1 = fs.GetFolder(startfolder)

For Each fl2 In fl1.SubFolders
    Debug.Print fl2.Path
    listfolders fl2.Path
Next

End Sub

@MatthiasPospiech也许您没有看到Dim行正上方的注释说明需要哪个引用,如果您不想添加引用,则建议替代？ (3认同)

这是一个 VBA 解决方案，不使用外部对象。

由于Dir()函数的限制，您需要一次获取每个文件夹的全部内容，而不是同时使用递归算法进行爬行。

Function GetFilesIn(Folder As String) As Collection
  Dim F As String
  Set GetFilesIn = New Collection
  F = Dir(Folder & "\*")
  Do While F <> ""
    GetFilesIn.Add F
    F = Dir
  Loop
End Function

Function GetFoldersIn(Folder As String) As Collection
  Dim F As String
  Set GetFoldersIn = New Collection
  F = Dir(Folder & "\*", vbDirectory)
  Do While F <> ""
    If GetAttr(Folder & "\" & F) And vbDirectory Then GetFoldersIn.Add F
    F = Dir
  Loop
End Function

Sub Test()
  Dim C As Collection, F

  Debug.Print
  Debug.Print "Files in C:\"
  Set C = GetFilesIn("C:\")
  For Each F In C
    Debug.Print F
  Next F

  Debug.Print
  Debug.Print "Folders in C:\"
  Set C = GetFoldersIn("C:\")
  For Each F In C
    Debug.Print F
  Next F
End Sub

此版本深入子文件夹并返回完整路径名，而不是仅返回文件或文件夹名称。

不要在整个 C 驱动器上运行测试！！

Function GetFilesIn(Folder As String, Optional Recursive As Boolean = False) As Collection
  Dim F As String
  Set GetFilesIn = New Collection
  F = Dir(Folder & "\*")
  Do While F <> ""
    GetFilesIn.Add JoinPaths(Folder, F)
    F = Dir
  Loop

  If Recursive Then
    Dim SubFolder, SubFile
    For Each SubFolder In GetFoldersIn(Folder)
      If Right(SubFolder, 2) <> "\." And Right(SubFolder, 3) <> "\.." Then
        For Each SubFile In GetFilesIn(CStr(SubFolder), True)
          GetFilesIn.Add SubFile
        Next SubFile
      End If
    Next SubFolder
  End If
End Function

Function GetFoldersIn(Folder As String) As Collection
  Dim F As String
  Set GetFoldersIn = New Collection
  F = Dir(Folder & "\*", vbDirectory)
  Do While F <> ""
    If GetAttr(Folder & "\" & F) And vbDirectory Then GetFoldersIn.Add JoinPaths(Folder, F)
    F = Dir
  Loop
End Function

Function JoinPaths(Path1 As String, Path2 As String) As String
  JoinPaths = Replace(Path1 & "\" & Path2, "\\", "\")
End Function

Sub Test()
  Dim C As Collection, F

  Debug.Print
  Debug.Print "Files in C:\"
  Set C = GetFilesIn("C:\")
  For Each F In C
    Debug.Print F
  Next F

  Debug.Print
  Debug.Print "Folders in C:\"
  Set C = GetFoldersIn("C:\")
  For Each F In C
    Debug.Print F
  Next F

  Debug.Print
  Debug.Print "All files in C:\"
  Set C = GetFilesIn("C:\", True)
  For Each F In C
    Debug.Print F
  Next F
