未在区域中调用 MVC 控制器

Question

我有一个无法正常工作的 MVC 控制器。

在一个页面上，我有一个表单，在该表单的某处有一个操作 link：

@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
<table>
        <tr>
            <th>
                @Html.ActionLink("Neues Gastkonto anlegen", "Index", "NewGuest", null, new { @class="button"})
            </th>
        </tr>
      ...
</table>
}

link 正确地呈现为 <host>/GluexDB/NewGuest。请注意，我在 GluexDB 区域工作，我的路线设置正确。

NewGuestController如下：

public class NewGuestController : Controller
{
    IGluexDBServiceFactory serviceFactory;

    //used for injecting the database
    public NewGuestController(IGluexDBServiceFactory serviceFactory)
    {
        if (serviceFactory == null)
        {
            throw new Exception("Please provide a valid serviceFactory");
        }

        this.serviceFactory = serviceFactory;
    }


    public ActionResult Index()
    {
        throw new NotImplementedException("CnG Cont"); //<-- no exception thrown here
        return View("CreateNewGuest");
    }

但是，点击第一页的link并没有抛出异常，而是告诉我The view 'Index' or its master was not found or no view engine supports the searched locations.即使不抛出异常，搜索到的View不应该被命名吗CreateNewGuest?

为了完整起见，这是路由配置：

public class GluexDBAreaRegistration : AreaRegistration 
{
    public override string AreaName 
    {
        get 
        {
            return "GluexDB";
        }
    }

    public override void RegisterArea(AreaRegistrationContext context) 
    {
        context.MapRoute(
            "GluexDB_default",
            "GluexDB/{controller}/{action}/{id}",
            new { action = "Index", id = UrlParameter.Optional }
        );
    }
}

感谢您为我指明正确的方向！

您需要添加如下区域的路由参数：

@Html.ActionLink("Neues Gastkonto anlegen", "Index", "NewGuest", 
                        new { area = "GluexDB"}, new { @class="button"})

更新

解决方案如下@Thaoden 的评论：

"Turns out, it was my code, in order to inject the serviceFactory, I had to overwrite GetControllerInstance of DefaultControllerFactory. I messed it up so that both TutorController (primary page) and NewGuestController returned an instance of TutorController, thus the NewGuestController would never be reached."
