System.IO.StringWriter html = new System.IO.StringWriter();
HtmlTextWriter tw = new HtmlTextWriter(html);
base.Render(tw);

禁用不必要的viewstate：这个大家都知道，页面中看不懂的长串字符就是viewstate，这大概会占用15%~40%左右的html代码量，减少viewstate势在必行，如果当前页面没有使用任何viewstate，而且又不想一个控件一个控件的关闭它，可以使用以下代码
protected override void Render(HtmlTextWriter writer)
{
System.IO.StringWriter html = new System.IO.StringWriter();
HtmlTextWriter tw = new HtmlTextWriter(html);
base.Render(tw);
string outhtml = html.ToString();
outhtml = System.Text.RegularExpressions.Regex.Replace(outhtml, "<input\\stype=\"hidden\"\\sname=\"__VIEWSTATE\"\\sid=\"__VIEWSTATE\" value=\".+\\/>", string.Empty);
outhtml = outhtml.Trim();
writer.Write(outhtml);
}
