为什么我的视图不使用我的编辑器模板文件夹进行创建操作

在我的MedicalProductController中，我试图通过IEnumerable<ViewModel>传递到视图，使我的Create和Delete操作能够在一个页面上创建和删除多个对象。我用于Create操作的方法适用于此堆栈溢出问题中的Edit操作。 但它不适用于我的create动作，所以我怀疑有些不对劲。

问题是页面上没有显示任何字段。 该页面在该页面上简单地说："创建"，"保存"（按钮），"返回列表"（可单击的链接）。 在"创建"和"保存"之间，应该有由MedicalProductViewModel.cshtml创建的html编辑器字段和标签，如下所示。

这是我的设置的样子。

Create.cshtml

@model IEnumerable<MvcMedicalStore.Models.MedicalProductViewModel>
@{
    ViewBag.Title = "Create";
}
<h2>Create</h2>
@using (Html.BeginForm()) {
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)
    <fieldset>
        <legend>MedicalProduct</legend>
        @Html.EditorFor(m => m)        
        <p>
            <input type="submit" value="Save" />
        </p>
    </fieldset>
}
<div>
    @Html.ActionLink("Back to List", "Index")
</div>
@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

编辑

我的

编辑视图与我的创建视图非常相似：

编辑.cshtml

@model IEnumerable<MvcMedicalStore.Models.MedicalProductViewModel>
@{
    ViewBag.Title = "Edit";
}
<h2>Edit</h2>
@using (Html.BeginForm()) {
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)
    <fieldset>
        <legend>MedicalProduct</legend>
        @Html.EditorFor(m => m)        
        <p>
            <input type="submit" value="Save" />
        </p>
    </fieldset>
}
<div>
    @Html.ActionLink("Back to List", "Index")
</div>
@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

public ActionResult Create()
{
    return View();
}

public ActionResult Create()
{
    return View(new List<MedicalProductViewModel>() { new MedicalProductViewModel() });
}

public class EditMedicalProductViewModel
{
    public IEnumerable<MedicalProductViewModel> MedicalProducts { get; set; }
}
public class CreateMedicalProductViewModel
{
    public MedicalProductViewModel MedicalProduct { get; set; }
}

@Html.EditorFor(m => m.MedicalProducts)

@Html.EditorFor(m=> m.MedicalProduct)   

return View(new CreateMEdicalProductViewModel() { MedicalProduct = new MedicalProductViewModel() } );

<fieldset>
    <legend>MedicalProduct</legend>
    @foreach(var item in Model)
    {
        Html.EditorFor(model => item)        
    }
    <p>
        <input type="submit" value="Save" />
    </p>
</fieldset>
