MVC开发程序中，session的用法

 public class UserBF

    {

        private masterDataContext _Context = new masterDataContext();

        public bool Login(string users,string pass)

        {

            var query = _Context.denglu.Where(p => p.users == users && p.pass == pass);

            return query.Count() > 0;

        }



    }







 public ActionResult Checkuidpwd(string uid,string pwd)

        {

            bool isok = new UserBF().Login(uid,pwd);



            if (isok == true)

            {

                //保存状态

                //把输入的用户名存在Session里

                Session["user"] = uid;

                //跳转界面

                return RedirectToAction("Index","Home");

            }

            else

            {

                return RedirectToAction("Index");

            }



        }





 public ActionResult Index()

        {

            //如果session里没有值，就证明没有登录，返回登录页面。不能跳过登录页面

            if (Session==null)

            {

                return RedirectToAction("index","login");

            }

            return View();

        }









  <div>欢迎您：@Session["user"].ToString()</div>
