    public class User
    {
        public int Id { get; set; } 
        public string Name { get; set; }
        public int CoopTime { get; set; }
        public DateTime JoinTime { get; set; }
    }

        public ActionResult Index()

            };
            //判断合作是否已经到期
            int result = DateTime.Compare(DateTime.Now, user.JoinTime.AddYears(user.CoopTime));
            if (result <= 0) //当前时间比合作到期时间早，合作未到期
            {
