Answer 1

Singleton<OnlineInfo> 是一个Singleton<T>，单件模式实现的类，没有做类是的在线统计，请大大们看看这样设计合理吗

把我做的登录的代码也放出来吧 这样清晰一些[AcceptVerbs(HttpVerbs.Post)]
        public ActionResult Login()
        {
            var guid = "";
            var json = new JsonMsg();
            var admin = new AdminInfoService();            AdminInfo user = null;            string name = Request.Form["name"];
            string pass = Request.Form["pass"];
            string code = Request.Form["code"];            //验证参数是否为空
            if (string.IsNullOrEmpty(name))
            {
                json.Msg = "账户名不能为空.";
                return Json(json);
            }
            else if (string.IsNullOrEmpty(pass))
            {
                json.Msg = "密码不能为空.";
                return Json(json);
            }
            else if (string.IsNullOrEmpty(code))
            {
                json.Msg = "验证码不能为空.";
                return Json(json);
            }            //验证验证码是否为空
            if (Session["Admin_valiCode"] != null)
            {
                if (Session["Admin_valiCode"].ToString() != code)
                {
                    json.Msg = "验证码错误.";
                    return Json(json);
                }
            }
            else
            {
                json.Msg = "验证码失效，请刷新.";
                return Json(json);
            }            //获取用户信息
            user = admin.GetInfo(name);            if (name.ToLower() == "admin")
            {
                //admin判断区                if (user == null)
                {                }
                else if (user.iPass != (name + pass).ToHash())

谢谢各位指点我后台有个线程 每一分钟就把更改状态的用户更新到数据库中 贴出代码来  /// <summary>
        /// 使用单例模式控制线程检测在线人员状态 
        /// </summary>
        private void SetLoopUsers()
        {
            if (!Singleton<Boolean>.Instance)
            {
                Singleton<Boolean>.Instance = true;
                Thread thCheck = new Thread(CheckOnline) { IsBackground = true, Priority = ThreadPriority.Lowest };
                thCheck.Start();
            }
        }        /// <summary>
        /// 检测用户状态(60秒一次),若有修改过的则存进数据库,下线的则删除
        /// </summary>
        private void CheckOnline() {            while (true)
            {
                var keys = new object[Users.GetUser().Count];
                Users.GetUser().Keys.CopyTo(keys, 0);                for (int i = keys.Length - 1; i >= 0; i--)
                {
                    var onUser = Users.GetUser(keys[i]) as OnlineInfo;
                    if (onUser != null && onUser.IsEdit)
                    {
                        //ToDo update online table
                        if (!onUser.IsOnline)
                        {
                            Users.DelUser(onUser.CookieId);
                        }
                    }
                }
                
                Thread.Sleep(60000);
            }
        }
