直接给大家分享一下脚本之家测试正常可以使用的代码,并且支持多级目录创建

代码一

Function CreateMultiFolder(ByVal CFolder)
Dim objFSO, PhCreateFolder, CreateFolderArray, CreateFolder
Dim i, ii, CreateFolderSub, PhCreateFolderSub, BlInfo
BlInfo=False
CreateFolder=CFolder
On Error Resume Next
Set objFSO=Server.CreateObject(“Scripting.FileSystemObject”)
If Err Then
Err.Clear()
Exit Function
End If
If Right(CreateFolder, 1)=”/” Then
CreateFolder=Left(CreateFolder, Len(CreateFolder) -1)
End If
CreateFolderArray=Split(CreateFolder, “/”)
For i=0 To UBound(CreateFolderArray)
CreateFolderSub=””
For ii=0 To i
CreateFolderSub=CreateFolderSub & CreateFolderArray(ii) & “/”
Next
PhCreateFolderSub=Server.MapPath(CreateFolderSub)
If Not objFSO.FolderExists(PhCreateFolderSub) Then
objFSO.CreateFolder(PhCreateFolderSub)
End If
Next
If Err Then
Err.Clear()
Else
BlInfo=True
End If
CreateMultiFolder=BlInfo
End Function

使用方法:

CreateMultiFolder(“/202003/tools/”)

代码二、测试ok

‘自动创建多极目录
‘code by jb51 reterry
function createit(path)
dim fsofo,cinfo,thepath,thepatharray
dim i,ii,binfo
binfo=false
thepath=path
set fsofo=createobject(“scripting.filesystemobject”)
if err then
err.clear
exit function
end if
thepath=replace(thepath,””,”/”)
if left(thepath,1)=”/” then
thepath=right(thepath,len(thepath)-1)
end if
if right(thepath,1)=”/” then
thepath=left(thepath,len(thepath)-1)
end if
thepatharray=split(thepath,”/”)
for i=0 to ubound(thepatharray)
createfoldersub1=createfoldersub1&thepatharray(i)&”/”
createfoldersub=server.mappath(createfoldersub1)
if not fsofo.folderexists(createfoldersub) then
fsofo.createfolder(createfoldersub)
end if
next
if err then
err.clear
else
binfo=true
end if
createit=binfo
end function

测试代码

createit(“/202004/tools/”)

以上代码如果无法运行,请检查iis运行用户的权限是否有写功能。今天测试的时候默认iis7.5下是无法运行的。

下面的实现代码功能性简单,适合学习

ASP如何检测某文件夹是否存在,不存在则自动创建

folder=server.mappath(“/imagess”) 
Set fso=CreateObject(“Scripting.FileSystemObject”) 
if fso.fileexists(Server.mappath(filepath)) then 
respnse.write(“都有了还建什么建”) 
else 
fso.createfolder(folder) 
end if 
Set fso=nothing

Dim objFSO 
Set objFSO=Server.CreateObject(“Scripting.FileSystemObject”) 
If objFSO.FolderExists(Server.MapPath(SavePath))=false Then 
objFSO.CreateFolder(Server.MapPath(SavePath)) 
End If

folder=server.mappath(“/imagess”) 
Set fso=CreateObject(“Scripting.FileSystemObject”) 
if fso.fileexists(Server.mappath(filepath)) then 
respnse.write(“都有了还建什么建”) 
else 
fso.createfolder(folder) 
end if 
Set fso=nothing  

都不完善,我想楼主的意思是创建无极深度目录吧,给个我写的: 

‘创建新文件夹(允许无级创建)1:35 2005-1-31

Public Function CreateFolder(FolderPath)
Dim sObjFSO
Dim arrFolder
Dim i

Set sObjFSO=Server.CreateObject(“Scripting.FileSystemObject”)
FolderPath=Replace(FolderPath,””,”/”)
arrFolder=Split(FolderPath,”/”)
On Error Resume Next

For i=0 To UBound(arrFolder)
If i > 0 Then arrFolder(i)=arrFolder(i-1) & “/” & arrFolder(i)
If Not sObjFSO.FolderExists(arrFolder(i)) Then
sObjFSO.CreateFolder(arrFolder(i))
End If
Next
CreateFolder=True

If Err.number <> 0 Then
CreateFolder=False
Err.Clear
End If
End Function

创建文件夹

dim fso,SavePath
SavePath=server.MapPath(“.”&imagefile&””&username&””&specialname&””)
set fso=server.CreateObject(“scripting.filesystemobject”)
if fso.FolderExists(SavePath)=false then
fso.createfolder(SavePath)
end if
set fso=nothing

删除文件夹

dim fso,SavePath
SavePath=server.MapPath(“.”&imagefile&””&username&””&specialname&””)
set fso=server.CreateObject(“scripting.filesystemobject”)
if fso.FolderExists(SavePath)=true then
fso.deletefolder(SavePath)
end if
set fso=nothing

复制文件

dim fso
set fso=server.CreateObject(“scripting.filesystemobject”)

sub copyfiles(path,path2)
set mycopy=fso.getfile(path)
response.flush()
mycopy.copy path2
response.write(“<b>installed success !  </b>”&path2&”<br>”)
response.Flush()
end sub
call copyfiles(Server.MapPath(“https://www.jb51.net/无标题2.bmp”),”D:\网站项目\photo\aspupload\07_images”)

下面是其他网友的补充 

Public Function CheckAndCreateFolder(FolderName)
  fldr=Server.Mappath(FolderName)
  Set fso=CreateObject(“Scripting.FileSystemObject”)
  If Not fso.FolderExists(fldr) Then
  fso.CreateFolder(fldr)
  End If
  Set fso=Nothing
End Function

 检查文件夹是否存在,不存在则创建文件夹,该函数无返回值。

例:CheckAndCreateFolder(“ASP”)

检查当前目录下是否存在ASP文件夹,不存在则创建文件夹ASP ,缺点是不支持多级目录创建。

 asp关于fso函数,文件与文件夹的相关操作用得到

‘//提供文件处理通用接口
Class FileSystemObject

Public Function DelFile(FileName)
Dim getPath
getPath=”/”
SET Fso=Server.CreateObject(“Scripting.FileSystemObject”)
getPath=Replace(getPath&FileName,”http://”,”/”)
if Fso.FileExists(Server.MapPath(getPath))=True then
  Fso.DeleteFile Server.mappath(getPath)
End if
Set Fso=Nothing
End Function


Public Function CreatePath(SaveFilePath)
Dim DeclarePath,FileObj,FilePath
DeclarePath=”/”

Set FileObj=Server.CreateObject(“Scripting.FileSystemObject”)
For Each FilePath in split(SaveFilePath,”/”)
  DeclarePath=Replace(DeclarePath&FilePath&”/”,”http://”,”/”)
  if FileObj.FolderExists(Server.MapPath(DeclarePath))=false then
    FileObj.CreateFolder(Server.MapPath(DeclarePath))’创建文件夹
  end if
Next
Set FileObj=nothing
CreatePath=DeclarePath
End Function


Public Function RenFolder(GetPath,OldName,NewName)
Dim Fso
if OldName=”” or NewName=”” then
  exit Function
else
  if OldName=NewName then exit Function
end if
SET Fso=Server.CreateObject(“Scripting.FileSystemObject”)
if Fso.FolderExists(Server.MapPath(GetPath&NewName)) then
  response.write”<script language=javascript>alert(‘目录已经存在!!’);this.history.go(-1);</script>”
  response.end()
end if
‘//旧的文件夹不存在,则创建
if Not Fso.FolderExists(Server.MapPath(GetPath&OldName)) Then
  CreatePath(GetPath&OldName)
End if

Fso.MoveFolder Server.MapPath(GetPath&OldName),Server.MapPath(GetPath&NewName)
set Fso=nothing
‘response.redirect request.ServerVariables(“HTTP_REFERER”)
End Function


Public Function SaveEditFile(GetPath,GetContent,GetFile)
if GetContent=”” or GetFile=”” then exit Function
SET Fso=Server.CreateObject(“Scripting.FileSystemObject”)
set CF=Fso.CreateTextFile(Server.mappath(GetPath&GetFile),true)
CF.write GetContent
CF.Close
set CF=nothing
set Fso=nothing
‘response.redirect request.ServerVariables(“HTTP_REFERER”)
End Function

End Class
