Question

＃我收到此错误，我不知道为什么我想请您帮助我解决它

我不知道怎么了，为什么会给出错误 Object reference not set to an instance of an objector of

“ /”应用程序中的服务器错误。你调用的对象是空的。说明：执行当前Web请求期间发生未处理的异常。请查看堆栈跟踪以获取更多信息有关错误及其在代码中起源的信息。
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Source Error: 


Line 19:     </tr>
Line 20: 
Line 21: @foreach (var item in Model) {
Line 22:     <tr>
Line 23:         <td>

我的控制器类如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using vidly.Models;


namespace vidly.Controllers
{
    public class CustomerController : Controller
    {
        // GET: Customer

        public ActionResult Index()
        {
            var  customerlist = new List<Customer>();

            customerlist.Add(new Customer { Name = "Shayan", id = 1 });
            customerlist.Add(new Customer { Name = "usman", id = 2 });
            customerlist.Add(new Customer { Name = "Affan", id = 3 });
            return View();
        }


    }
}

我的模型课是在

下

 using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;

    namespace vidly.Models
    {
        public class Customer
        {
            public int id { get; set; }
            public string Name { get; set; }

        }
    }

我的看法与

相同

 @model IEnumerable<vidly.Models.Customer>

{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Index</h2>

<p>
    @Html.ActionLink("Create New", "Create")
</p>
<table class="table">
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.Name)
        </th>
        <th></th>
    </tr>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.id)

        </td>
        <td>
                      @Html.DisplayFor(modelItem => item.Name)
        </td>
        <td>
            @Html.ActionLink("Edit", "Edit", new { id=item.id }) |
            @Html.ActionLink("Details", "Details", new { id=item.id }) |
            @Html.ActionLink("Delete", "Delete", new { id=item.id })
        </td>
    </tr>
}

</table>

必须更改哪个代码段以及为什么

ASP点网MVC错误
