MVC:字典需要类型为“System.Collections.Generic.IEnumerable"1 的模型项 [英] MVC: Dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1

问题描述

我收到这个错误，我不确定我是否能够做到这一点，这是我的代码..

I am getting this error and I'm not sure if I am able to do this, here is my code..

应用控制器

public ActionResult AppView()
{
    List<Application> apps;
    using (ISiteDbContext context = _resolver.GetService<ISiteDbContext>())
    {
        apps = context.Applications.ToList();
    } 
    return PartialView("AppView", apps.OrderBy(a => a.Name).ToList());
}

渲染部分 - 这是在主控制器中的视图中.

Render partial - this is within a view which is in the home controller.

@{Html.RenderPartial("~/Views/Application/AppView.cshtml", new Example.Services.DAL.Application());} 

和我的应用程序视图

@model IEnumerable<Example.Services.DAL.Application>

@{
    ViewBag.Title = "Applications";
}

<h2>Applications</h2>

<p>
    @Html.ActionLink("Add New Application", "Create")
</p>
<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>

完整的错误信息:

传入字典的模型项是类型'Example.Services.DAL.Application'，但是这本字典需要一个型号型号'System.Collections.Generic.IEnumerable`1[Example.Services.DAL.Application]'.

The model item passed into the dictionary is of type 'Example.Services.DAL.Application', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[Example.Services.DAL.Application]'.

推荐答案

由于错误表明您传递了错误的类型.改变

As error states you are passing a wrong type. Change

@{Html.RenderPartial("~/Views/Application/AppView.cshtml", new Example.Services.DAL.Application());}

到:

@{Html.RenderPartial("~/Views/Application/AppView.cshtml", new List<Example.Services.DAL.Application> { new Example.Services.DAL.Application() });}
