//测试页面代码

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="testDemo.aspx.cs" Inherits="testweb.testDemo" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

//测试页面后台

using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Html=System.Web.UI.HtmlControls;
namespace testweb
{
    //Page_Init在Page_Load前执行
    public partial class testDemo : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Html.HtmlAnchor link2 = (Html.HtmlAnchor)Page.FindControl("link2");
            Response.Write(link2.InnerHtml);
            link2.Visible = false;
        }
        protected void Page_Init(object sender, EventArgs e)
        {
            Template.BindTemplateToPage(this, "/模版页面.html");
        }
    }
}

结果：

这个是直接在本页面输出，还能用runat="server"的控件，

附：生成静态页方法

可结合使用。
