.NET如何输出紧凑HTML页面

如题，有没简单方便的实现办法。谢谢

何为紧凑? 这应该和.net 本身关系不大吧

把控件放在div中，用margin控制

比如
<div>
  dsa
</div>
我要输出<div>dsa</div>
有些浏览器认空格和回车的，比较麻烦，手动删除太累，有没好的办法输出紧凑的HTML代码

别按回车键和空格键

private static readonly Regex REGEX_LINE_BREAKS = new Regex(@"\n\s*", RegexOptions.Compiled); 
  private static readonly Regex REGEX_LINE_SPACE = new Regex(@"\n\s*\r", RegexOptions.Compiled); 
  private static readonly Regex REGEX_SPACE = new Regex(@"( )+", RegexOptions.Compiled); 
  protected override void Render(HtmlTextWriter writer) 
  { 
  using (HtmlTextWriter htmlwriter = new HtmlTextWriter(new System.IO.StringWriter())) 
  { 
  base.Render(htmlwriter); 
  string html = htmlwriter.InnerWriter.ToString(); 
  html = REGEX_LINE_BREAKS.Replace(html, string.Empty);
  html = REGEX_LINE_SPACE.Replace(html, string.Empty);
  html = REGEX_SPACE.Replace(html, " ");
  writer.Write(html.Trim()); 
  } 
  }
