在初始请求时验证模型

Question

我正在将一个模型返回给我关于页面初始加载的视图，模型是从数据库中填充的，我想验证模型，以便当用户收到页面时，验证摘要显示错误（如果有的话）

我尝试过使用TryValidateModel（模型），但是这不起作用，它不会更新ModelState，我认为它只能验证从ModelBinder中填充的内容

这周围有吗？我只是想先验证模型，而无需用户将其发回...

        [Authorize, HttpGet, ActionName("StepOne")]
    public ActionResult StepOneGET(StepOneModel model)
    {
        var individual = _onsideService.Get(User.Identity.Name);

        model.PersonalInformation = new PersonalInformationModel
                                        {
                                            FirstName = individual.FirstName,
                                            LastName = individual.LastName,
                                            DoB = individual.DateOfBirth.ToString("dd/MM/yyyy"),
                                            Email = individual.DefaultEmail.EmailAddress,
                                            Phone = individual.DefaultPhone.Number,
                                            AddressLine1 = location.Address1,
                                            AddressLine2 = location.Address2,
                                            City = location.City,
                                            PostCode = location.PostalCode,
                                            Country = location.Country
                                        };

        // NOTE: Does not update ModelState
        TryValidateModel(model);

        // Need to return potential errors to user on page load

        return View(model);     
    }
