asp读取指定目录下的文件名-学习asp编程

bianli(Server.MapPath(“/”)+”pic”)

InStrRev(“abcd.jpg”, “.”) 计算出abcd.jpg中第一次出现.所在的位置是第几个字符=5

mid(“abcd.jpg”,1,4) 取前四位abcd

mid(“abcd.jpg”,5) 从五位往后取（包括第五位） .jpg

取前缀abc

FullPath = “abc.jpg”
f = mid(FullPath,1,InStrRev(FullPath, “.”)-1)
Response.Write f

娶后缀jpg

FullPath = “abc.jpg”
f = mid(FullPath,InStrRev(FullPath, “.”)+1)
Response.Write f

生用的遍历文件：

<%@language=”vbscript” codepage=”65001″%>
<%
Response.Expires = 0
function bianli(path)
dim fso ‘fso对象
dim objFolder ‘文件夹对象
dim objFiles ‘文件集合
dim objFile ‘文件对象
set fso=server.CreateObject(“scripting.filesystemobject”)
on error resume next
set objFolder=fso.GetFolder(path)’创建文件夹对象
set objSubFolders=objFolder.Subfolders’
for each objSubFolder in objSubFolders
nowpath=path + objSubFolder.name + “”
Response.Write nowpath
set objFiles=objFolder.Files
for each objFile in objFiles
Response.Write (objFile.name)
Response.Write ”
”
Next
bianli(nowpath) ‘调用递归
next
set objFolder=nothing
set objSubFolders=nothing
set fso=nothing
end function
%>
<% bianli(Server.MapPath(“/”) + “/new”) ‘调用bianli()函数,这里是遍历当前目录下的new文件夹 %>

—————————————————————————————————-

<%
Set fso=Server.CreateObject(“Scripting.FileSystemObject”)’创建一个Folder对象
fpath=”.”‘Request.form(“fpath”)
set objfolder=fso.getfolder(server.mappath(fpath))
for each objsubfolder in objfolder.subfolders
Response.write “子文件夹名称:” & objsubfolder.name & ”
”
next
Response.write ”

for each objfile in objfolder.files
Response.write objfile.name & ”
”
exitname=fso.GetExtensionName(objfile.name)’文件后缀也可以用这获取f = mid(thing,InStrRev(thing, “.”)+1)’取asp后缀的文件 f=”asp”
response.Write exitname & ”

next
