.net如何获取文件夹中的文件_access递归列出文件夹中的文件

本文介绍如何在VBA中递归列出文件，在列表框中显示文件路径和文件名

前面的我们讲过类似的实例《Access获取文件夹内的文件名及路径》，下面函数的功能更加完整

Public Function ListFiles(strPath As String, Optional strFileSpec As String, _ Optional bIncludeSubfolders As Boolean, Optional lst As ListBox)On Error GoTo Err_Handler 'Purpose: List the files in the path. 'Arguments: strPath = the path to search. ' strFileSpec = "*.*" unless you specify differently. ' bIncludeSubfolders: If True, returns results from subdirectories of strPath as well. ' lst: if you pass in a list box, items are added to it. If not, files are listed to immediate window. ' The list box must have its Row Source Type property set to Value List. 'Method: FilDir() adds items to a collection, calling itself recursively for subfolders. Dim colDirList As New Collection Dim varItem As Variant  Call FillDir(colDirList, strPath, strFileSpec, bIncludeSubfolders)  'Add the files to a list box if one was passed in. Otherwise list to the Immediate Window. If lst Is Nothing Then For Each varItem In colDirList Debug.Print varItem Next Else For Each varItem In colDirList lst.AddItem varItem Next End IfExit_Handler: Exit FunctionErr_Handler: MsgBox "Error " & Err.Number & ": " & Err.Description Resume Exit_HandlerEnd FunctionPrivate Function FillDir(colDirList As Collection, ByVal strFolder As String, strFileSpec As String, _ bIncludeSubfolders As Boolean) 'Build up a list of files, and then add add to this list, any additional folders Dim strTemp As String Dim colFolders As New Collection Dim vFolderName As Variant 'Add the files to the folder. strFolder = TrailingSlash(strFolder) strTemp = Dir(strFolder & strFileSpec) Do While strTemp <> vbNullString colDirList.Add strFolder & strTemp strTemp = Dir Loop If bIncludeSubfolders Then 'Build collection of additional subfolders. strTemp = Dir(strFolder, vbDirectory) Do While strTemp <> vbNullString If (strTemp <> ".") And (strTemp <> "..") Then If (GetAttr(strFolder & strTemp) And vbDirectory) <> 0& Then colFolders.Add strTemp End If End If strTemp = Dir Loop 'Call function recursively for each subfolder. For Each vFolderName In colFolders Call FillDir(colDirList, strFolder & TrailingSlash(vFolderName), strFileSpec, True) Next vFolderName End IfEnd FunctionPublic Function TrailingSlash(varIn As Variant) As String If Len(varIn) > 0& Then If Right(varIn, 1&) = "" Then TrailingSlash = varIn Else TrailingSlash = varIn & "" End If End IfEnd Function

在名为“lstFileList”列表框，并设置行来源类型为“值列表”

在代码中调用函数， Call ListFiles("D:OfficeCnOffice Addin
