Question

我收到此错误，我不明白为什么：传递到字典中的模型项的类型为'Devart.Data.Linq.DataQuery`1 [CHRContext.WIKIIDEE]'，但此字典需要“CHRContext.WIKIREPARTO”类型的模型项。

来自模型的

方法

public IQueryable<WIKIIDEE> GetIdeasByDeptID(int id)
        {
            var query = from i in db.WIKIIDEEs
                        where i.IDREPARTO == id
                        select i;

            return query;
        }

来自控制器的

方法

public ActionResult List(int id)
    {
        try
        {
            IdeeRepository ideeRepo = new IdeeRepository();

            IQueryable<WIKIIDEE> list = ideeRepo.GetIdeasByDeptID(id);

            return View(list);
        }
        catch (Exception Ex)
        {
            return View("Error");
        }
    }

并查看

 @model IEnumerable<CHRContext.WIKIIDEE>

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

<h2>List</h2>

<p>
    @Html.ActionLink("Create New", "Create")
</p>
<table>
    <tr>
        <th>
            IDREPARTO
        </th>
        <th>
            DATAINSERIMENTO
        </th>
        <th>
            DESCRIZIONE
        </th>
        <th></th>
    </tr>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.IDREPARTO)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.DATAINSERIMENTO)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.DESCRIZIONE)
        </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>

我遇到了一个非常类似的问题，并且能够解决它。你可以在我的回答中看到如何：The model item passed into the dictionary is of type A, but this dictionary requires a model item of type B
