  1.   

    Regex.Replace(input.ToString().Trim(), @"(<link(.|\n)*?\/>)", "", RegexOptions.IgnoreCase);
    Regex.Replace(input.ToString().Trim(), @"(<iframe(.|\n)*?<\/iframe>)", "", RegexOptions.IgnoreCase);
      

  2.   

    Regex.Replace(input.ToString().Trim(), @"(<script(.|\n)*?<\/script>)", "", RegexOptions.IgnoreCase);
      

  3.   

    组合一下也行Regex.Replace(内容, @"(<link(.|\n)*?\/>)|(<script(.|\n)*?<\/script>)", "", RegexOptions.IgnoreCase)
      

  4.   

    (?isx)
    <
     (?>
      (?'open'script[^>]*>)
      |(?'-open'</script)
      |(?:(?!</script).)*
     )*
    (?(open)(?!))
    >
    |<link\s*rel="stylesheet"[^>]*>
