Question

我使用以下方法从控制器编辑

编辑了房屋的属性

public ActionResult Edit(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            House house = repository.GetHouseById((int)id);
            if (house == null)
            {
                return HttpNotFound();
            }
            NewHouse newHouse = new NewHouse()
            {
                House = house,
                Types = repository.getAvaiableTypes()
            };
            return View(newHouse);
        }
public ActionResult Edit([Bind(Include = "Id,Description,Type,Price")] House house,string selectedTypeText)
        {
            ModelState.Clear();
            house.Type = selectedTypeText;

            if (ModelState.IsValid)
            {
                try
                {
                    repository.UpdateHouse(house);
                    repository.SaveChanges();
                    return RedirectToAction("Index");
                }
                catch
                {
                    ViewBag.exception = true;
                    return View(house);
                }

            }
            return View(house);
        }

我在ModelView NewHouse中使用类，其结构如下所示

public class NewHouse
    {
        public House House { get; set; }

        public IEnumerable<SelectListItem> Types { get; set; }

        public int SelectedTypeId { get; set; }

        [Display(Name = "Typ domku")]
        public string SelectedTypeText { get; set; }
    }

当我保存更改时，对象House和字段selectedTypeText中的所有字段都将传递给POST方法。但我有一个错误

传递到字典中的模型项的类型为＆＃39; Repository.Models.House＆＃39;，但此字典需要类型为＆＃39; Repository.ViewModels.NewHouse的模型项。

我清除ModelState，但它没有帮助。我应该如何绑定在POST方法中传递对象House和字段selectedTypeText？在Edit.cshtml中，我使用@model Repository.ViewModels.NewHouse

正如@Prabhat已经提到的，你需要改变

[Bind(Include = "Id,Description,Type,Price")] House house

到

[Bind(Include = "Id,Description,Type,Price")] NewHouse house

此外，您应该更改视图中输入字段的名称，例如：

<input ... name="Description" ...>

到

<input ... name="House.Description" ...>

错误的modelItem传入Asp.net mvc中的字典
