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。
