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：

   /// <summary>  
        /// 重写Render方法，来压缩输出的内容  
        /// </summary>  
        /// <param name="writer"></param>  
        protected override void Render(HtmlTextWriter writer)
        {
            StringWriter html = new StringWriter();
            HtmlTextWriter tw = new HtmlTextWriter(html);
            base.Render(tw);

            string outhtml = html.ToString();
           
              outhtml = Regex.Replace(outhtml, @"\s+", " ", RegexOptions.Compiled | RegexOptions.Multiline);
          outhtml = Regex.Replace(outhtml, "\\r\\n", string.Empty, RegexOptions.Compiled | RegexOptions.Multiline);
          outhtml = Regex.Replace(outhtml, @"(?<=>)(\s|\n|\t)+(?=<)", string.Empty, RegexOptions.Compiled | RegexOptions.Multiline);
         outhtml = Regex.Replace(outhtml, "<!--*.*?-->", string.Empty, RegexOptions.Compiled | RegexOptions.Multiline);
         

            //输出到客户端  
            writer.Write(outhtml);
        }  

          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。
