c# 调用迅雷下载漫画

鉴于家里网速的问题，上同人の侍这个工口网站很慢而且提心吊胆而且一页一页的翻着很麻烦~于是出现了同人の侍专用漫画下载器~ALPHA版

同人の侍网址：http://samurai3.net/

已完成功能：下载大部分的漫画

欠缺：部分漫画的命名：有的是000~00n

有的是00~n 未作相关处理，对于漫画页是否有效未作验证如漫画实际命名为000.JPG 001.JPG 002.JPG 099.JPG

会从000.jpg一直尝试下载到099.jpg 而对无效的003.jpg~098.jpg未作处理（处理方法很简单 不过懒得做了~）

程序使用方法：给出标准网址如火影：http://samurai3.net/doujinshi/naruto.html

                                                         死神：http://samurai3.net/doujinshi/bleach.html

                                                         海贼王：http://samurai3.net/doujinshi/onepeace.html

(应该是one piece对吧 所以说日本人啊~)

双击给出的可用下载漫画列表中的某项即开始下载

PS:本程序需在项目中加载迅雷组件的引用 因为webclient.dowmloadfile()不支持断点续传，自己实现起来挺麻烦，迅雷的弹出确认对话框也很麻烦 这里采取的方法是用线程池监视并自动确认 有好方法的同志望不吝赐教~
