重写 Render(HtmlTextWriter writer) 方法产生的问题？？？
protected override void Render(HtmlTextWriter writer)
{
writer.Write(@ " <html> ");
writer.WriteLine();
writer.Write(@ " <head> ");
writer.WriteLine();
writer.Write(@ " </head> ");
writer.WriteLine();
writer.Write(@ " <title> ");
writer.WriteLine();
writer.Write( "测试链接数据库时的效率 ");
writer.Write(@ " </title> ");
writer.WriteLine();
writer.Write(@ " <body> ");
writer.WriteLine();
ShowTable(writer);
writer.Write(@ " </body> ");
writer.WriteLine();
writer.Write(@ " </html> ");
writer.Close();
base.Render(writer);
}
生产表格成果，但在查看该网页的源文件时，原来的这个页面的前台标签并没有被清空？请问这是什么原因，应该怎么处理？
源文件：
<html>
<head>
</head>
<title>
测试链接数据库时的效率 </title>
<body>
....
</body>
</html>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN " "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
<html xmlns= "http://www.w3.org/1999/xhtml " >
<head> <title>
无标题页
</title> <link href= "App_Themes/gridview/gridview.css " type= "text/css " rel= "stylesheet " /> </head>
<body>
<form name= "form1 " method= "post " action= "dynamicTable.aspx " id= "form1 ">
<div>
<input type= "hidden " name= "__VIEWSTATE " id= "__VIEWSTATE " value= "/wEPDwUJNzgzNDMwNTMzZGSqGnvZWg2k52Y8hPUMkkmvsgVRjQ== " />
</div>
<div>
</div>
</form>
</body>
</html>
如何除掉后面这一段html标签？
------解决方案--------------------
把那句base.Render(writer)去掉看看！

HtmlTextWriter还有其他的方法
比如writer.RenderBeginTag(HtmlTextWriterTag
protected override void Render(HtmlTextWriter writer)
{
writer.Write(@ " <html> ");
writer.WriteLine();
writer.Write(@ " <head> ");
writer.WriteLine();
writer.Write(@ " </head> ");
writer.WriteLine();
writer.Write(@ " <title> ");
writer.WriteLine();
writer.Write( "测试链接数据库时的效率 ");
writer.Write(@ " </title> ");
writer.WriteLine();
writer.Write(@ " <body> ");
writer.WriteLine();
ShowTable(writer);
writer.Write(@ " </body> ");
writer.WriteLine();
writer.Write(@ " </html> ");
writer.Close();
base.Render(writer);
