Cookie的写入，和读取

    public static void SetLoginGmameInfo(string  uid, string sid, string timestring, string sign)
        {
            //System.Web.HttpContext.Current.Session["GoGoPortalmemberSessionUserID"] = userID.ToString();
            //System.Web.HttpContext.Current.Session["GoGoPortalmemberSessionUserName"] = userName;
            //System.Web.HttpContext.Current.Session["GoGoPortalmemberSessionUserPWD"] = userPWD;
            //ClearLoginSession();
            /上面是session方式；下面是cookie方式
            System.Web.HttpCookie membercookie = System.Web.HttpContext.Current.Request.Cookies["GoGoGameInfoCookie"];
            if (membercookie == null)
            {
                membercookie = new System.Web.HttpCookie("GoGoGameInfoCookie");
            }
            //membercookie.Expires = DateTime.Now ;//默认是关闭浏览器就失效，不保存到磁盘
            membercookie.Values.Set("uid", uid.ToString());
            membercookie.Values.Set("sid", sid);
            membercookie.Values.Set("timestring", timestring);
            membercookie.Values.Set("sign", sign);
      
            //membercookie.Expires = DateTime.Now.AddHours(4);//设置cookie过期时间
            System.Web.HttpContext.Current.Response.SetCookie(membercookie);

        }

上面的一个方法就是将uid,sid,timestring,string sign写入的cookie里面去了，cookie默认是关闭浏览器失效

那我们改如何使用这个方法呢SetLoginGmameInfo(uid, sid, time.ToString(), Sign);这样就写入了Cookie

取出Cookie

比如我要取出COOKIE里面我已经存入的UID

   /// <summary>
        /// 返回session的userid
        /// </summary>
        /// <returns></returns>
        public static string GetLoginUidCookie()
        {
           
            string Uid = "0";
            System.Web.HttpCookie membercookie = System.Web.HttpContext.Current.Request.Cookies["GoGoGameInfoCookie"];
            if (membercookie != null)
            {
                Uid = membercookie["uid"].ToString();
            }
            return Uid;
        }

然后定义一个变量string uid=GetLoginUidCookie();//就取出来Cookie了
