Question

求一句asp代码--获取当前文件夹文件个数

运行asp页面，能显示当前目录里面文件个数。包括子目录里面的文件
页面显示一个数量数字即可，不需要名称。
感谢楼下回答。但是测试过好像都不行呀~~~
望指点

Answer 1

'返回指定文件夹中文件的数目，传入值为被检测文件夹的硬盘绝对路径
function CountFilesNumber(folderspec)
Dim objfso,f,fc
Set objfso=CreateObject("Scripting.FileSystemObject")
Set f=objfso.GetFolder(folderspec)
Set fc=f.Files
CountFilesNumber=fc.Count
set fc=nothing
set f=nothing
set objfso=nothing
End Function

Answer 2

<%
Set FSO=Server.CreateObject("Scripting.FileSystemObject") .
Response.Write FSO.GetFolder(Server.MapPath("/")).Files.Count
%>
