牛腩购物网30：用户中心其他功能制作(获取购物的总金额，判断用户是 普通会员还是VIP会员，用户申请VIP)

1：获取购物的总金额

 //积分
     litIntegral.Text = u.integral.ToString() ;

    //购物总金额
     litALLTotalPrice.Text = new DAL.OrderDAO().CalcCount("username='" + User.Identity.Name + "' and state=5 and isdel=0 ").ToString();


   //收藏的商品数
    LitFavCount.Text = new DAL.FavoriteDAO().CalcCount("username='" + User.Identity.Name +"'").ToString(); 

2:判断用户的类别

//在登陆的窗口这里，如果登陆后，显示是什么会员类型
            if (Page.User.Identity.IsAuthenticated)
            {
                Model.User u = new DAL.UserDAO().GetModel(Page.User.Identity.Name);
                if (u!=null)
                {
                    Literal litIsVip = LoginView1.FindControl("litIsVip") as Literal;
                    litIsVip.Text = u.type == "normal" ? "普通会员" : "VIP会员";
                    
                }
            }

 

3:申请VIP

//申请VIP
        protected void btnSqVip_Click(object sender, EventArgs e)
        {
            Model.User u = new DAL.UserDAO().GetModel(User.Identity.Name);

            if (u != null)
            {
                if (u.type == "vip")
                {
                    Utility.Tool.alert("您已经是VIP会员", this.Page);
                    return;
                }
                else
                {
                    if (u.integral < 10000)
                    {
                        Utility.Tool.alert("您的积分不足10000分，不能申请VIP", this.Page);
                        return;
                    }
                    else
                    {
                        new DAL.UserDAO().UpdateType(User.Identity.Name, "vip");
                        Utility.Tool.alert("vip会员申请成功", Request.Url.ToString(), this.Page);
                        return;
                    }
                }
            }
        }

 

//修改会员为 VIP会员
        public void UpdateType(string username, string type)
        {

            string sql = "update shop_user set integral=integral-10000,type=@type where username=@username";

            Database db = DatabaseFactory.CreateDatabase();
            DbCommand dbcommand=db.GetSqlStringCommand(sql);
            db.AddInParameter(dbcommand, "type", DbType.String, type);
            db.AddInParameter(dbcommand, "username", DbType.String, username);
            db.ExecuteNonQuery(dbcommand);
