C#实现支撑断点续传多线程下载客户端工具类

代码如下:

/* .Net/C#: 实现支持断点续传多线程下载的 Http Web 客户端工具类 (C# DIY HttpWebClient)

* Reflector 了一下 System.Net.WebClient ,改写或增加了若干:

* DownLoad、Upload 相关方法!

* DownLoad 相关改动较大!

* 增加了 DataReceive、ExceptionOccurrs 事件!

* 了解服务器端与客户端交互的 HTTP 协议参阅:

* 使文件下载的自定义连接支持 FlashGet 的断点续传多线程链接下载! JSP/Servlet 实现!

* http://blog.csdn.net/playyuer/archive/2004/08/02/58430.aspx

* 使文件下载的自定义连接支持 FlashGet 的断点续传多线程链接下载! C#/ASP.Net 实现!
