加入文件夹中的结构：

引入了函数公式的图标：

想把内容保存进去，但是有HTML标签，正则处理的代码：

 public static string CleanHtml(string strHtml){if (string.IsNullOrEmpty(strHtml))return strHtml;//删除脚本//strHtml = Regex.Replace(strHtml, "(+'\'+<script(.+?)+'\'+</script+'\'+>)|(+'\'+<style(.+?)+'\'+</style+'\'+>)", "", RegexOptions.IgnoreCase | RegexOptions.Singleline);strHtml = Regex.Replace(strHtml, @"<script[^>]*?>.*?</script>", "", RegexOptions.IgnoreCase);//删除标签var r = new Regex(@"</?[^>]*>", RegexOptions.IgnoreCase);Match m;for (m = r.Match(strHtml); m.Success; m = m.NextMatch()){strHtml = strHtml.Replace(m.Groups[0].ToString(), "");}return strHtml.Trim();}
