今天我们讲解如何利用asp的上传功能将本地的文件上传到服务器上。
最简系统包括下面三个文件：

upload.htm                        --上传口文件，选择本地文件
uploadimg.asp                 --上传程序控制文件
upload_5xsoft.inc            --无组件上传类，此文件初学者不用学习，只要会用就可以了

upload.htm内容————上传口文件，选择本地文件

<html><head></head><body><table width="80%" border="0" align="center"><form name="form1" method="post" action="uploadimg.asp" enctype="multipart/form-data"><tr>  <td align="center"><input name="upfile" type="file" id="upfile"></td> </tr>   <tr>  <td align="center"><input type="submit" name="Submit" value="上传图片"></td> </tr> </form></table></body></html>

uploadimg.asp内容————上传程序控制文件

<!--#include FILE="upload_5xsoft.inc"--><%dim upload,file,filepathfilepath="UPLOAD/"set upload=new upload_5xSoft ''建立上传对象for each formName in upload.file ''列出所有上传了的文件 set file=upload.file(formName) ''生成一个文件对象 if file.FileSize>0 then     ''如果 FileSize > 0 说明有文件数据 fname = file.filename file.SaveAs Server.mappath(filepath&fname)  ''保存文件 end ifset file=nothingnextset upload=nothing ''删除此对象

upload_5xsoft.inc内容————此文件内容不属于本演练程序内容，本演练应用此类的方法
