未找到路径'/'的控制器或未实现IController

Question

我正在编写一段代码,在每个网页上显示随机赞助商图片.我认为调用我的函数的最佳位置是在Views/Shared/_Layout.cshtml页面中,因为那是在每个页面加载的那个.

我在我的域模型的服务类中编写了ChildActionOnly函数,并在我的homecontroller中编写了一个函数,在Views/Home/Randomsponsor.cshtml的简单视图中返回值,并在Html.action的共享布局中调用该函数.

一切都很好,但运行时我得到下一个错误:

{"The controller for path '/' was not found or does not implement IController."}

有谁知道如何解决这个问题？

域项目中的方法:

public String advertsForCountry()
{
    String studentSchool = finder.getLoggedStudent().SchoolId;
    int studentCountry = db.Schools.Find(studentSchool).CountryId;

    List<Sponsor> sponsorsForStudent = new List<Sponsor>();
    List<Advert> adverts = db.Adverts.ToList();
    foreach(Advert adv in adverts)
    {
        foreach(Country cntry in adv.Countries)
        {
            if(cntry.CountryId == studentCountry)
            {
                sponsorsForStudent.Add(adv.Sponsor);
            }
        }
    }
    Random random = new Random();
    int randomSP = random.Next(0, sponsorsForStudent.Count()-1);
    string sponsorAdvert = sponsorsForStudent.ElementAt(randomSP).SponsorCompany;
    return sponsorAdvert;       
}

在HomeController中:

[HttpGet]   
[ChildActionOnly]
public ActionResult RandomSponsor()
{
    var model = service.advertsForCountry();

    return PartialView("RandomSponsor", model);
}

在Views/Home /中的简单视图:

@{
    ViewBag.Title = "RandomSponsor";
}

@Html.Action("RandomSponsor")

我在View/Shared/_Layout.cshtml中的函数调用whitch包含导航栏等:

@Html.Action("RandomSponsor", "HomeController")

问候.

您无需在中指定Controller的完整类名Html.Action.尝试使用 @Html.Action("RandomSponsor", "Home")而不是@Html.Action("RandomSponsor", "HomeController").
