Question

请允许我在前言中说其他SO问题没有回答我的问题。

我是ASP.net的新手，我正在关注一些在线教程。现在，我在传递模型时遇到了问题。错误是：

传递到字典中的模型项的类型为“Vidly.ViewModels.DetailCustomersViewModel”，但此字典需要“Vidly.ViewModels.RandomMovieViewModel”类型的模型项。

然而，这对我没有意义，因为我不记得设置任何字典。以下代码适用于我的电影页面。

视图模型：

namespace Vidly.ViewModels
{
    public class RandomMovieViewModel
    {

        public Movie Movie { get; set; }
        public List<Customer> Customers { get; set; }

    }
}

控制器：

namespace Vidly.Controllers
{
    public class MoviesController : Controller
    {
        // GET: Movies/random
        public ActionResult Random()
        {

            var movie = new Movie() { Name = "Shrek!" };

            var customers = new List<Customer>
            {
                new Customer { Name = "Michael"},
                new Customer { Name = "SlowPC"}
            };

            var movieModel = new RandomMovieViewModel
            {
                Movie = movie,
                Customers = customers
            };

            return View(movieModel);
            //return Content("Hello World");
            //return HttpNotFound();

            //return new EmptyResult();
            //return RedirectToAction("Index", "Home", new { page = 1, sortBy = "name" });
        }
}

在我们的CSHTML中，我们将其称为：

@model Vidly.ViewModels.RandomMovieViewModel
@{ 
    ViewBag.Title = "Random";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

@{ 
    var className = Model.Customers.Count > 5 ? "popular" : null;
}

然而，当我为我的DetailsCustomer做同样的事情时，它会抛出错误，我不知道为什么

视图模型：

namespace Vidly.ViewModels
{
    public class DetailCustomersViewModel
    {

        public List<Customer> Customers { get; set; }

    }
}

控制器：

namespace Vidly.Controllers
{
    public class CustomersController : Controller
    {

        [Route("customers/details/{Id}")]
        public ActionResult Details(int? Id)
        {

            var customers = new List<Customer>
            {
                new Customer { Id = 1, Name = "Jane Doe"},
                new Customer { Id = 2, Name = "John Smith"}
            };

            var customersModel = new DetailCustomersViewModel
            {
                Customers = customers
            };

            return View(customersModel);
        }
}

CSHTML：

@model Vidly.ViewModels.DetailCustomersViewModel
@{
    ViewBag.Title = "Details";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

@{
    var className = Model.Customers.Count > 5 ? "popular" : null;
}


<h2 class="@className">Customers</h2>

正如你可以想象的那样，当我真正传递正确的类型时，我对于如何存在类型不匹配感到十分困惑;而且我没有回忆过修改字典。

ASP.NET字典类型不匹配
