Я пытаюсь отправить List<Theatres> с целью управления с помощью AJAXPass Мультиэкземпляр в целях контроллера с использованием Ajax
каждый theates имеют TheatresName (строка), TheatresNumber (INT), HomeCinemaID (INT), RowAmount (целое).
здесь код модели:
public class MovieTheaters
{
[Key]
public int MovieTheatersID { get; set; }
public int HomeCinemaID { get; set; }
public string TheatersName { get; set; }
public int NumberHall { get; set; }
public int RowAmount { get; set; }
//FK .
public virtual HomeCinema HomeCinema { get; set; }
public virtual ICollection<Rows> Rows { get; set; }
}
пользователю вводить сколько театров ему нужно, то для цикла дал возможность создать их.
код вид:
@model CimenaCityProject.Models.MovieTheaters
@{
ViewBag.Title = "Create";
}
<h2>Create New Theatres</h2>
@Html.AntiForgeryToken()
@{
int? maxNumberOfTheatres = ViewBag.number;
if (!maxNumberOfTheatres.HasValue)
{
maxNumberOfTheatres = 1;
}
}
@using (Html.BeginForm("Create", "Theatres", FormMethod.Post, new { name = "TheatresForm", id = "TheatresForm" }))
{
@Html.ValidationSummary(true)

{

время Эври это бросить мне нуль .. то, что я есть в делать?
Можете ли вы предоставить код контроллера & модель Б ?? –
ok я отредактировал сообщение –
Где именно это выбрасывает исключение? В поле зрения или в контроллере? Как насчет возврата JsonResult в контроллере smth вроде: return Json (Data, JsonRequestBehavior.AllowGet); – Fabjan
