我看了看，找遍了谷歌，但我发现PHP的例子吗？
I looked and searched all over google, but I found PHP examples?
据我了解，你会沿着这条
I understand you would do something along the lines of this
HtmlElement downloadlink = webBrowser1.Document.GetElementById("song_html").All[0];
URL = downloadlink.GetAttribute("href");
但我不明白如何由类秀王来做到这一点。
but I do not understand how to do it by the class "show1".
请点我与示例和/或一个网站，我可以访问，所以我可以学习如何做到这一点，因为我搜查，没有任何线索。
Please point me in the right direction with examples and/or a website I can visit so I can learn how to do this as I searched and have no clue.
编辑：我非常需要在href链接（http://dc182.4shared.com/img/1011303409/865387c9/dlink__2Fdownload_2F6QmedN8H_3Ftsid_3D20111211-54337-a79f8d10/preview.mp3），这样会怎样我得到它？
I pretty much need the href link ("http://dc182.4shared.com/img/1011303409/865387c9/dlink__2Fdownload_2F6QmedN8H_3Ftsid_3D20111211-54337-a79f8d10/preview.mp3"), so how would I obtain it?
推荐答案
有什么内置在 web浏览器控件来检索类名的元素。既然你知道这将是一个 A 元素，你能做的最好的就是让所有的 A 元素和搜索你想要的：
There is nothing built-in in the WebBrowser control to retrieve an element by class name. Since you know it is going to be an a element the best you can do is get all a elements and search for the one you want:
var links = webBrowser1.Document.GetElementsByTagName("a");
foreach (HtmlElement link in links)
{
if (link.GetAttribute("className") == "show1")
{
//do something
}
}
