大家都发觉，在安装WEB程序时，最麻烦之处在于上传网站程序文件，大多数虚似主机只提供FTP功能，但有时网速较慢的时候，上传几M的文件就用了差不多一个多钟，尤其当文件较多的时候。等待上传文件的时间就够等。或者大家都会想到，如果能打包起来，上传后再解包，这样就好了。
这里提供的方法原理基本上是一样，主要利用 ICSharpCode.SharpZipLib.dll组件实现在线解压。
由于还利用到了DLL的动态加载，所以在这里记下来。分享给大家。
源代码如下：

进度条利用到了

下面是安装过程。
1,上传单个文件到网站根目录
运行
http://beachblue.cn/Setup.aspx
点击在线安装
这样，本来要上传几十分钟的网站文件，不用一分钟就上传完成。
（因为是远程下载，服务器下载较快）
但由于解压后，增加了web.config，应用程序重启，所以不能删除自身，不能做到完美。
有解决方法的可以提出。

晕。。太多人在测试，大家下载源码后测试吧。。
那文件我在删了
