[ASP.net教程]压缩html


       最近研究程序的优化,压缩html可以减小html的体积,有利于提高页面的相应速度。在webform的basepage中添加如下代码:

 1  /// <summary>  2     /// 重写Render方法,来压缩输出的内容  3     /// </summary>  4     /// <param name="writer"></param>  5     protected override void Render(HtmlTextWriter writer) 6     { 7       StringWriter html = new StringWriter(); 8       HtmlTextWriter tw = new HtmlTextWriter(html); 9       base.Render(tw);10 11       string outhtml = html.ToString();12      13        outhtml = Regex.Replace(outhtml, @"\s+", " ", RegexOptions.Compiled | RegexOptions.Multiline);14      outhtml = Regex.Replace(outhtml, "\\r\\n", string.Empty, RegexOptions.Compiled | RegexOptions.Multiline);15      outhtml = Regex.Replace(outhtml, @"(?<=>)(\s|\n|\t)+(?=<)", string.Empty, RegexOptions.Compiled | RegexOptions.Multiline);16     outhtml = Regex.Replace(outhtml, "<!--*.*?-->", string.Empty, RegexOptions.Compiled | RegexOptions.Multiline);17     18 19       //输出到客户端 20       writer.Write(outhtml);21     } 

          具体到相应项目当中,还是需要调试以下,以免过滤需要输出的内容。
