本文介绍了一种在ASP.NET应用程序中使用HtmlTextWriter类来构建HTML源代码的方法，并提供了两种实现方式：一种使用StringBuilder和StringWriter，另一种使用MemoryStream和StreamWriter。通过这两种方式可以灵活地创建复杂的HTML结构。

I need to render some html in my asp.net applications sometime, I chose HtmlTextWriter to build the html source because I can use those handy methods of this object such as RenderBeginTag, AddAttribute, and so on. I know two ways to do this.

1 StringBuilder sb = new StringBuilder();
2             using(StringWriter sw = new StringWriter(sb))
3             {
4                 using(HtmlTextWriter output = new HtmlTextWriter(sw))
5                 {
6                     output.RenderBeginTag(HtmlTextWriterTag.Table);
7                     for(int y=0; y<1000; y++)
8                     {
9                         output.RenderBeginTag(HtmlTextWriterTag.Tr);
