我有一个要求,我需要从这个HTML获取链接

" GOOGLE CORPORATION     
   09  -  Analytics Company "

我需要的输出是

Details.aspx?entityID=1&hash=20&searchFunctionID=53b&type=Advanced&nameSet=Entities&q=a&textSearchType=ExactPhrase&orgTypes=01%2c02%2c03%2c04%2c05%2c06%2c07%2c08%2c09%2c10%2c11%2c12%2c13%2c14%2c15%2c16%2c90%2c96%2c98%2c99

我用了

string sPattern ="[

这不是给我正确的输出.任何人都可以指出我正确的方向.

如上所述,使用Regex解析HTML 并不是一个好主意.我建议你使用HtmlAgilityPack(你可以从NuGet获得它):

HtmlDocument hdoc = new HtmlDocument();            
hdoc.LoadHtml(@"<span class=""name""><a href=Details.aspx?entityID=1&hash=20&searchFunctionID=53b&type=Advanced&nameSet=Entities&q=a&textSearchType=ExactPhrase&orgTypes=01%2c02%2c03%2c04%2c05%2c06%2c07%2c08%2c09%2c10%2c11%2c12%2c13%2c14%2c15%2c16%2c90%2c96%2c98%2c99> GOOGLE CORPORATION  </a> </span>  <br /> <span class=typeDescription>  09  -  Analytics Company </span>");
var href = hdoc.DocumentNode.SelectSingleNode("//a").Attributes["href"].Value;

它为您提供href属性值.
