关闭浏览器清除Cookies - 编程论坛

小弟现在在做一个购物车,用Cookies
            HttpCookie hc = null;
            if (Request.Cookies["MyGouWuChe"] == null)
            {
                hc = new HttpCookie("MyGouWuChe");
            }
            else
            {
                hc = Request.Cookies["MyGouWuChe"];
            }
            if (Request.QueryString["ShopGoodsInfoCode"] != null && Request.QueryString["ShopGoodsName"] != null && Request.QueryString["BuyCount"] != null && Request.QueryString["Price"] != null)
            {
                if (hc.Values == null)
                {
                    hc.Values.Add(Request.QueryString["ShopGoodsInfoCode"].ToString(), Request.QueryString["ShopGoodsInfoCode"].ToString() + "|" + Request.QueryString["ShopGoodsName"].ToString() + "|" + Request.QueryString["BuyCount"].ToString() + "|" + Request.QueryString["Price"].ToString());
                    hc.Expires = DateTime.Now.AddMinutes(30);//过期时间为30分钟
                    Response.Cookies.Add(hc);
                }
                else
                {
                    hc.Values.Add(Request.QueryString["ShopGoodsInfoCode"].ToString(), Request.QueryString["ShopGoodsInfoCode"].ToString() + "|" + Request.QueryString["ShopGoodsName"].ToString() + "|" + Request.QueryString["BuyCount"].ToString() + "|" + Request.QueryString["Price"].ToString());
                    hc.Expires = DateTime.Now.AddMinutes(30);//过期时间为30分钟
                    Response.Cookies.Add(hc);
                }
            }
现在想关闭浏览器的时候把购物车里面的数据全部清除了
在Global.asax里面的

程序代码：

void Application_End(object sender, EventArgs e)
    {
        Response.Cookies.Clear();
        //  在应用程序关闭时运行的代码

    }

这样写就可以了?
