如何使用C#清理HTML标记

在C#中删除HTML标记的最佳方法是什么？

任何人都可以通过解释如何从C#中的HTML文件中提取网址/链接来帮助我

Regex hrefs = new Regex("<a href.*?>");
Regex http = new Regex("http:.*?>");  
StringBuilder sb = new StringBuilder();
WebClient client = new WebClient();
string source = client.DownloadString("http://google.com");
foreach (Match m in hrefs.Matches(source)){
sb.Append(http.Match(m.ToString()));
Console.WriteLine(http.Match(m.ToString()));
}

代码工作正常,但只有一次问题看输出.
