using System;

namespace FM.Web

{

    //作用：校验用户是否登录，如果登录则获取用户信息，否则跳转到登录页面

    //调用：子类继承此类，override重写Page_Load方法，并调用父类的的Page_Load方法：base.Page_Load(sender,e)

    public class MyBasePage:System.Web.UI.Page

    {

        public Model.Member loginUser {get; set; }

        protected virtual void Page_Load(object sender, EventArgs e)

        {

            loginUser = (Model.Member)Session["user"];

            if (loginUser == null)

            {

                Response.Redirect("~/Pattern_1/Member/Login.aspx");

            }
