asp.net-mvc-5 – MVC AttributeRoute似乎忽略了RoutePrefix并导

Multiple controller types were found that match the URL. This can happen if attribute routes on multiple controllers match the requested URL.

The request has found the following matching controller types:
FFInfo.WebUI.Areas.Admin.Controllers.HomeController
FFInfo.WebUI.Areas.Admin.Controllers.SectionController

这只发生在我去/ Admin / Sections /并且我不确定为什么因为只有一条路线可以匹配该URL,任何人都可以帮我弄清楚什么是错的？请注意这个问题是5.1.2独有的,MVC 5.0工作正常.

基础控制器：

[RouteArea("Admin")]
public class BaseController : Controller
{
}

家庭控制器：

[RoutePrefix("")]
[Route("{action}")]
public class HomeController : BaseController
{

    public ActionResult Index()
    {
    }

    public ActionResult Updates()
    {
    }

    [ChildActionOnly]
    public PartialViewResult GetUpdatesGrid()
    {
    }


    public ActionResult GetUpdates(JqGridRequest Request)
    {
    }
}

部门控制器：

[RoutePrefix("Sections")]
[Route("{action}")]
public class SectionController : BaseController
{
    [Route]
    public ActionResult Sections()
    {
    }

    [ChildActionOnly]
    public PartialViewResult GetSectionsGrid()
    {
    }

    public ActionResult GetSections(JqGridRequest Request)
    {
    }

    public ActionResult AddSection()
    {
    }

    [HttpPost,ValidateAntiForgeryToken]
    public ActionResult AddSection(AddEditSectionVM model,HttpPostedFileBase LogoFile)
    {
    }

    public ActionResult EditSection(Int16? ID)
    {
    }

    [HttpPost,ValidateAntiForgeryToken]
    public ActionResult EditSection(AddEditSectionVM model,HttpPostedFileBase Logo)
    {
    }

    public ActionResult Releases()
    {
    }

    [ChildActionOnly]
    public PartialViewResult GetReleasesGrid()
    {
    }

    public ActionResult GetReleases(JqGridRequest Request)
    {
    }

    public ActionResult AddRelease()
    {
    }

    [HttpPost,ValidateAntiForgeryToken]
    public ActionResult AddRelease(AddEditReleaseVM model)
    {
    }
}

我对RouteArea RoutePrefix和Route属性的理解告诉我/ Admin / Index将调用Home Controller的Index ActionResult,URL Admin / Sections应该调用Sections Controller的Index ActionResult.所有其他路线在每个控制器中都能正常工作,当您进入/ Admin / Index工作正常时.当我进入/ Admin / Sections时,我只收到此错误.怎么了？
