我正在尝试打开名称以ToDo.xlsx结尾的所有文件,方法是执行遍历所有子文件夹的循环。
我在StackOverflow的另一篇文章中发现了这个循环,但是当有很多文件时(在我的情况下约为35k)需要花费太多时间:
Public Sub NonRecursiveMethod()
Dim fso, oFolder, oSubfolder, oFile, queue As Collection
Set fso = CreateObject("Scripting.FileSystemObject")
Set queue = New Collection
queue.Add fso.GetFolder("your folder path variable") 'obviously replace
Do While queue.Count > 0
Set oFolder = queue(1)
queue.Remove 1 'dequeue
'...insert any folder processing code here...
For Each oSubfolder In oFolder.SubFolders
queue.Add oSubfolder 'enqueue
Next oSubfolder
For Each oFile In oFolder.Files
'...insert any file processing code here...
Next oFile
Loop
End Sub
我的处理代码是:
If InStr(oFile.Name,"ToDo"= <> 0 Then Workbooks.Open Filename:=oSubfolder & oFile
有没有办法将这个条件放在for循环中,以便最小化处理时间?
谢谢

代替For each
循环,尝试以下lop更快:
filename = Dir(oFolder.Name & "\*ToDo.xlsx")
While (filename <> "")
' processing... Full name is oFolder.Name & "\" & filename
filename = Dir
