What i will hhave to do to resolve my problem kindly help me to get out of it thankx in advance

What I have tried:

Here is View

@model IEnumerable<SearchBox.Models.Students>

@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>



@using (Html.BeginForm())
{
    <div class="form-horizontal">
        <div class="form-group">
            @Html.LabelFor(model => model.Name, "Name", htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-8">
                @Html.EditorFor(model => model.Name, new { htmlattributes = new { @class = "form-control" } })
            </div>
        </div>
    </div>
}



        <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.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>

控制器

Controller

public class DefaultController : Controller
    {
        private static List<Students> students = new List<Students>()
        {
            new Students() {Id = 1, Name = "Student - 1"},
            new Students() {Id = 2, Name = "Student - 2"},
            new Students() {Id = 3, Name = "Student - 3"},
            new Students() {Id = 4, Name = "Student - 4"},
            new Students() {Id = 5, Name = "Student - 5"},
            new Students() {Id = 6, Name = "Student - 6"},
            new Students() {Id = 7, Name = "Student - 7"},
            new Students() {Id = 8, Name = "Student - 8"},
            new Students() {Id = 9, Name = "Student - 9"}
        };


        // GET: Default
        public ActionResult Index()
        {
            return View(students);
        }
    }

推荐答案

声明

The declaration

@model IEnumerable<SearchBox.Models.Students>

告诉视图，提供的数据是一种类型为Students的集合 - 这可以在循环中使用。



声明

tells the view, that the provided data is a kind of collection of type Students - this can be used in a loop.

The declaration

@model SearchBox.Models.Students

告诉视图，只有一个类型为student的对象（而不是集合），因此需要循环。

tells the view that there is only a single object of type students (instead of a collection) and therefor there is noting to loop through.

引用：

但我如何在我的视图中使用它们。

but how i can use both in my view.

它应该在这种方式，如果你只需要从一个模型展示

it shall be done in this way if you need to show from only one model

<div class="form-group">
           @Html.LabelFor(model => model.First().Name, "Name", htmlAttributes: new { @class = "control-label col-md-2" })
           <div class="col-md-8">
               @Html.EditorFor(model => model.First().Name, new { htmlattributes = new { @class = "form-control" } })
           </div>
       </div>

否则使用此 MVC中单视图中的多个模型 [ ^ ]
