cookie语法

   一：  /// cokkie记录客服端的信息
        /// 通常用来记录客服的信息，也有时候用着记录购物车的信息
        /// </summary>
        /// 创建一个名称为user的cookie的对象
        HttpCookie cookie = new HttpCookie("user");
        //给cookie赋值
       // cookie.Value = "jinpeilong";
        cookie["sex"] = "男";
        cookie.Values.Add("age", 30);
        //控制cookie的时间
        cookie.Expires = DateTime.Now.AddHours(1);
        //保持cookie
        Response.AppendCookie(cookie);

二：

     HttpCookie cokkies = Request.Cookies["user"];
        if (null == cookies)
        {
            Response.Write("没指定cookie");
        }
        else
        {
            Response.Write("Cookie的全部值为："+cokkies.Values+"<br>");
            Response.Write("sex的值为:" + cokkies["sex"] + "<br>");
            Response.Write("age的值为："+cokkies.Values["age"]+"<br>");
        }
