private string NoHTML(string Htmlstring)

//删除脚本
Htmlstring = Regex.Replace(Htmlstring,@"<script[^>]*?>.*?</script>","",RegexOptions.IgnoreCase);
//删除HTML
Htmlstring = Regex.Replace(Htmlstring,@"<(.[^>]*)>","",RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring,@"([\r\n])[\s]+","",RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring,@"-->","",RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring,@"<!--.*","",RegexOptions.IgnoreCase);
Htmlstring= System.Text.RegularExpressions.Regex.Replace(Htmlstring, "<[^>]*>", "");  string pattern = @"<[\s\S]*?>";
Regex regex = new Regex(pattern);
Htmlstring = regex.Replace(Htmlstring,"");

Htmlstring = Regex.Replace(Htmlstring,@"&(quot|#34);","\"",RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring,@"&(amp|#38);","&",RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring,@"&(lt|#60);","<",RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring,@"&(gt|#62);",">",RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring,@"&(nbsp|#160);"," ",RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring,@"&(iexcl|#161);","\xa1",RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring,@"&(cent|#162);","\xa2",RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring,@"&(pound|#163);","\xa3",RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring,@"&(copy|#169);","\xa9",RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @"&#(\d+);","",RegexOptions.IgnoreCase);
Htmlstring=Regex.Replace(Htmlstring,@"<style(.[^>]*)>","",RegexOptions.IgnoreCase); Htmlstring.Replace("<","");

Answer 2

第一个
str="....";
Regex reg=new Regex(@"(?<=([\<]script[\>])[\s\S]+(?=([\<][\/]script[\>]))");
MatchCollection m1=reg.Matches(str);for(int i=0;i<m1.Count;i++)
{
  MessageBox.Show(m1[i].Value);//要取的在<script>与</script>之间的所有字符串
}
第二个
Regex reg=new Regex(@"(?<=([\<][\s]+href[\s]*=[\s]*\")[\s\S]+(?=(\"))");
