路径的控制器 ... 未找到或未实现 IController [英] The controller for path ... was not found or does not implement IController

问题描述

我正在使用 c# 编写使用 ASP.NET MVC 5 的应用程序.我需要在应用程序的右上角添加一个全局菜单.我被告知 其他 SO 使用带有 ChildActionOnly 属性的操作.

I am writing an application using ASP.NET MVC 5 using c#. I have a need to add a global menu on the upper right hand side of the application. I was advised other SO to use action with ChildActionOnly attribute.

这就是我所做的.

我创建了一个这样的 BaseController

I created a BaseController like this

public class BaseController : Controller
{

    [ChildActionOnly]
    public ActionResult ClientsMenu()
    {
        using (SomeContext db = new SomeContext())
        {
            return PartialView(db.Database.SqlQuery<Client>("SELECT * FROM clients").ToList());
        }
    }

}

然后我像这样从 BaseController 继承了我所有的控制器

Then I inherited all my controllers from BaseController like so

public class TasksController : BaseController
{

    public ActionResult Index(int ClientId)
    {
        ...
        return View();
    }

    public ActionResult Show(int SurveyId)
    {
        ...
        return View();
    }

}

为了在我的布局中呈现 ClientsMenu，我添加了以下代码

To render the ClientsMenu in my layout I added the following code

@Html.Action("ClientsMenu", "Menus")

现在当我运行我的应用程序时出现以下错误

Now when I run my application I get the following error

The controller for path '/Tasks/Index' was not found or does not implement IController.

当我从布局中删除 @Html.Action("ClientsMenu", "Menus") 时，一切正常，但全局菜单当然不显示.

When I remove @Html.Action("ClientsMenu", "Menus") from the layout everything works fine but the global menu does not show of course.

我该怎么做才能解决这个问题?

What can I do to resolve this issue?

已更新这是我从下面的评论中获得反馈后所做的

Updated Here is what I have done after the feedback I got from the comments below

public class TasksController : Controller
{
    [ChildActionOnly]
    public ActionResult ClientsMenu()
    {
        using (SomeContext db = new SomeContext())
        {
            return PartialView(db.Database.SqlQuery<Client>("SELECT * FROM clients").ToList());
        }
    }

    public ActionResult Index(int ClientId)
    {
        ...
        return View();
    }

    public ActionResult Show(int SurveyId)
    {
        ...
        return View();
    }

}

还是一样的错误

推荐答案

从 BaseController 中取出 ClientMenus Action 并将其放入自己的控制器 MenusController.然后，您可以从您的视图中调用该控制器.

Take ClientMenus Action out of the BaseController and put it into its own controller MenusController. You can then call that controller from your Views.

@Html.Action("ClientsMenu", "Menus")

在您的示例中，您没有 @Html.Action("ClientsMenu", "Menus") 正在寻找的 MenusContoller.

In your example you don't have a MenusContoller which is what @Html.Action("ClientsMenu", "Menus") is looking for.
