asp 中处理文件上传以及删除时常用的自定义函数:

  

以下为引用的内容:

  ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
  '所有自定义的VBS函数
  ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
  function DeleteFile(Filename) '删除文件
  if Filename<>"" then
  Set fso = server.CreateObject("Scripting.FileSystemObject")
  if fso.FileExists(Filename) then
  fso.DeleteFile Filename
  end if
  set fso = nothing
  end if
  end function
  ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
  function CreateDIR(byval LocalPath) '建立目录的程序,如果有多级目录,则一级一级的创建
  on error resume next
  LocalPath = replace(LocalPath,"\","/")
  set FileObject = server.createobject("Scripting.FileSystemObject")
  patharr = split(LocalPath,"/")
  path_level = ubound(patharr)
  for i = 0 to path_level
  if i=0 then pathtmp=patharr(0) & "/" else pathtmp = pathtmp & patharr(i) & "/"
  cpath = left(pathtmp,len(pathtmp)-1)
  if not FileObject.FolderExists(cpath) then FileObject.CreateFolder cpath
  next
  set FileObject = nothing
  if err.number<>0 then
  CreateDIR = false
  err.Clear
  else
  CreateDIR = true
  end if
  end function
