Кажется, это общий вопрос.Я посмотрел на множество примеров, но я должен что-то упустить.Ниже приведен мой код для «ViewModel» и «Controller».
ViewModel:
public class EditAddressViewModel
{
public Guid AddressUI { get; set; }
[Display(Name = "Billing Address?")]
[UIHint("_IsStatus")]
public bool IsBilling { get; set; }
[Display(Name = "Shipping Address?")]
[UIHint("_IsStatus")]
public bool IsShipping { get; set; }
[Display(Name = "Location Name")]
public string LocationName { get; set; }
[Display(Name = "Contact Name")]
public string ContactName { get; set; }
[Display(Name = "Address")]
public string Line1 { get; set; }
[Display(Name = "Address 2")]
public string Line2 { get; set; }
[Display(Name = "Country")]
public int Country { get; set; }
[Display(Name = "State")]
public int State { get; set; }
[Display(Name = "City")]
public int City { get; set; }
[Display(Name = "ZipCode")]
public string ZipCode { get; set; }
[Display(Name = "Contact Email")]
[DataType(DataType.EmailAddress)]
[StringLength(320)]
[RegularExpression(@"[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?", ErrorMessage = "Enter a valid email address")]
public string EmailAddress { get; set; }
[Display(Name = "Phone Number")]
[DataType(DataType.PhoneNumber)]
[StringLength(12)]
[RegularExpression(@"((\(\d{3}\) ?)|(\d{3}-))?\d{3}-\d{4}", ErrorMessage = "Enter a valid phone number")]
public string PhoneNumber { get; set; }
[Display(Name = "Fax Number")]
[DataType(DataType.PhoneNumber)]
[StringLength(12)]
[RegularExpression(@"((\(\d{3}\) ?)|(\d{3}-))?\d{3}-\d{4}", ErrorMessage = "Enter a valid phone number")]
public string FaxNumber { get; set; }
public int CompanyId { get; set; }
[Display(Name = "Select Country")]
public int CountryId { get; set; }
public IEnumerable<SelectListItem> Countries { get; set; }
[Display(Name = "Select State")]
public int StateId { get; set; }
public IEnumerable<SelectListItem> States { get; set; }
[Display(Name = "Select Cit;y")]
public int CityId { get; set; }
public IEnumerable<SelectListItem> Cities { get; set; }
}
Controller:
// Customer Input
// GET: Addresses/Edit/5
[Authorize(Roles = "CompanyAdmin")]
public ActionResult UserEdit(Guid guid)
{
if (guid == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
Addresses addresses = db.Addresses.Find(guid);
if (addresses == null)
{
return HttpNotFound();
}
EditAddressViewModel editAddress = new EditAddressViewModel()
{
AddressUI = addresses.AddressUI,
LocationName = addresses.LocationName,
Line1 = addresses.Line1,
Line2 = addresses.Line2,
Country = addresses.Country,
State = addresses.State,
City = addresses.City,
ZipCode = addresses.ZipCode,
PhoneNumber = addresses.PhoneNumber,
FaxNumber = addresses.FaxNumber,
CompanyId = addresses.CompanyId
};
ConfigureViewModel(editAddress);
return View(editAddress);
}
public void ConfigureViewModel(EditAddressViewModel editAddressViewModel)
{
editAddressViewModel.Countries = db.Countries.Select(o => new SelectListItem()
{
Value = o.CountryId.ToString(),
Text = o.CountryName
});
editAddressViewModel.States = db.States.Select(o => new SelectListItem()
{
Value = o.StateId.ToString(),
Text = o.StateName
});
editAddressViewModel.Cities = db.Cities.Select(o => new SelectListItem()
{
Value = o.CityId.ToString(),
Text = o.CityName
});
}
// POST: Addresses/Edit/5

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult UserEdit(EditAddressViewModel model)
{
var userId = User.Identity.GetUserId();
if (!ModelState.IsValid)
{
return View(model);
}
Addresses addresses = db.Addresses.Find(model.AddressUI);
addresses.IsBilling = EditAddressViewModel.IsBilling;
addresses.IsShipping = EditAddressViewModel.IsShipping;
addresses.LocationName = EditAddressViewModel.LocationName;
addresses.Line1 = EditAddressViewModel.Line1;
addresses.Line2 = EditAddressViewModel.Line2;
addresses.Country = EditAddressViewModel.Country;
addresses.State = EditAddressViewModel.State;
addresses.City = EditAddressViewModel.City;
addresses.ZipCode = EditAddressViewModel.ZipCode;
addresses.PhoneNumber = EditAddressViewModel.PhoneNumber;
addresses.FaxNumber = EditAddressViewModel.FaxNumber;
addresses.CompanyId = EditAddressViewModel.CompanyId;
db.Entry(addresses).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index", "Customer", new { UserId = userId });
}
Проблема, с которой я сталкиваюсьнаходится в контроллере.Все записи для примера
addresses.IsBilling = EditAddressViewModel.IsBilling;
показывают, что «Ссылка на объект требуется для нестатического поля, метода или свойства».Если я перехожу к своей 'ViewModel' и изменяю "public int или string" на "public static int", то он исчезает, но затем я получаю ошибку в действии get, которая не может быть привязана к статическому объекту.Я немного сбит с толку, потому что этот же сценарий работает для другого вопроса на этом сайте.По моему это не так.Я должен что-то упустить где-то.спасибо за вашу помощь.
