问 题

我已阅读,htmlagility 1.4是一个很好的解决方案,以刮的网页。作为一个新的程序员,我希望我能得到这个项目的一些投入。 我做的这是一个c#应用程序的形式。我有工作的页面是相当简单的。我需要的信息被套牢仅有2标签之间 。我的目标是拉动数据对部分民,马努 - 号,说明,马努国,上次修改,上次修改通过了网页和数据发送到sql表。一个转折是,也有一个小png pic卡还需要从src抓起="/一部分code /号。

我没有任何完成code的炒菜锅。我想到了code此位会告诉我,如果我是朝着正确的方向发展。即使步入调试,我不能看到它做任何事情。可能有人可能指向我在正确的方向上这一点。越详细越好,因为很明显我有很多东西要学。谢谢你,我会真的ap preciate吧。


静态无效的主要(字串[] args)
的htmldocument doc =新的htmldocument();
doc.loadhtml("http:// localhost"的); //我的理解这读取整个页面?
无功表= doc.documentnode.selectnodes("//表"); //我认为这将会使搜索包含表字
