今天下午整理文件上传的例子，感觉收集到的例子都很不人性话，后来找到一个还可以的，本来想改成类似于腾讯QQ相册那种方式，仔细看了一下是Flash的, 而且那个极速上传插件也不知道用什么做的？问了一下，说是什么cgi. 搞得一头雾水！
后来朋友推荐了一个这个叫uploadify的上传插件，似乎挺好，就到官方下了个示例运行，感觉挺好，自己再稍加美化一下就OK 了..!
接下来就讲讲使用过程吧：
1. 下载
官方网站：http://www.uploadify.com/
直接下载：jquery.uploadify-v2.1.0.zip
我的Demo: MyUpload.rar 官方网站也有demo
下载解压后：
说明：它里面有demo 但是是PHP的，还有一个帮助文档：uploadify v2.1.0 Manual.pdf.
2.创建工程：
结构如图>>
文件说明：
A.js文件夹下的所有文件:必需,从下载下来的包里解压复制过来，名字可以自己改改
B.Default.aspx：测试页，后台没有代码
代码
<%@ Page Language="C#" AutoEventWireup="true" Codebehind="Default.aspx.cs" Inherits="WebApplication2._Default" %>

D.upload这个文件加也是必需
3.运行结果：
4.最后说说：这个只是一个简单的入门例子，至于界面可以根据自己的需要去改
