C# 在注册页的“throw”语句处获取用户未处理的异常

我正在创建带有密码验证的自定义注册页面。以前我尝试用JavaScript方法来实现这一点，但这些努力都失败了

对于前端验证，我使用Getter和setter调用Re_Enter_Password。现在我尝试在Getter和setter之上添加[NotMapped]属性

问题是，当我尝试使用视图插入注册详细信息时，我在控制器类的throw语句中得到了用户未处理的异常

我使用ADO.NET实体数据模型来访问数据库。我没有在数据库表中定义字段调用重新输入密码

这是我的控制器类：HECController.cs

        }

        [HttpGet]
        public ActionResult HEI_Registration()
        {
            return View();
        }



        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult HEI_Registration(AFFEMS2_HEC.Models.HEI_REG_TABLE user)
        {
            try
            {
                if (ModelState.IsValid)
                {
                    using (var db = new AFFEMS2_HEC.Models.HEI_REG_DBEntities())

                        newUser.Title = user.Title;

                        newUser.Lastname = user.Lastname;
                        newUser.Email = user.Email;
                        newUser.Direct_Number = user.Direct_Number;
                        newUser.Mobile_Number = user.Mobile_Number;
                        newUser.Password = encrypPass;
                        newUser.PasswordSalt = crypto.Salt;

                        db.HEI_REG_TABLE.Add(newUser);

                else

                    ModelState.AddModelError("", "Data is not correct");
                }
            }
            catch (DbEntityValidationException e)
            {

                foreach (var eve in e.EntityValidationErrors)
                {
                  Console.WriteLine("Entity of type \"{0}\" in state \"{1}\" has the following validation errors:",
                       eve.Entry.Entity.GetType().Name, eve.Entry.State);
                    foreach (var ve in eve.ValidationErrors)
                    {
                        Console.WriteLine("- Property: \"{0}\", Error: \"{1}\"",ve.PropertyName, ve.ErrorMessage);

            }
            return View();

        public ActionResult LogOut()
        {

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

        private bool IsValid(string email, string password)
        {
            var crypto = new SimpleCrypto.PBKDF2();
            bool IsValid = false;

            using (var db = new AFFEMS2_HEC.Models.HEI_REG_DBEntities())
            {
                var user = db.HEI_REG_TABLE.FirstOrDefault(u => u.Email == email);
                if (user != null)
                {
                    if (user.Password == crypto.Compute(password, user.PasswordSalt))
                    {
                        IsValid = true;
                    }
                }
            }
            return IsValid;
        }


    }

那么，在你的捕获中，你抛出了错误，错误的细节是什么？@DavidG这是我得到的错误这是我得到的错误
