HtmlHead类动态添加<head>中子标签，如<title>和<style>，尤其是后者，就是动态配置CSS。例子如下：
protected void Page_Load(object sender, EventArgs e)
{
Style bodyStyle = new Style(); bodyStyle.ForeColor = System.Drawing.Color.Red; bodyStyle.BackColor = System.Drawing.Color.Black; Page.Header.StyleSheet.CreateStyleRule(bodyStyle, null, "BODY"); Page.Header.Title = "这里写Title";
}HtmlMeta类负责动态增加Meta标签，一般用不到，反正我是不用，代码示例如下：
protected void Page_Load(object sender, EventArgs e) { HtmlMeta meta = new HtmlMeta(); meta.Name = ""; meta.Content = ""; HtmlHead head = (HtmlHead)Page.Header; head.Controls.Add(meta); }
