HTML Agility Pack是一个很好的库来解析C＃中的HTML。

提取网址的示例是：

var html = "<a href=\"http://reallife.com/2014/06/22/new-idea-about-life.zip\">New idea about life (zip) (25MB)</a><a href=\"http://reallife.com/2014/06/22/new-idea-about-life-rar.rar\">New idea about life (rar) (23MB)</a>
var htmlDoc = new HtmlDocument();
htmlDoc.LoadHtml(html);
var links = new List<string>();
foreach (var link in htmlDoc.DocumentNode.SelectNodes("//a[@href]"))
{
    links.Add(link.GetAttributeValue("href", string.Empty));    
}
// do something with the links inside the links-List
