@html.action cs代码,c# - @Html.Action and Controllers with same name - Stack Overflow

While creating a Plugin for a MVC site, I'm facing an issue about controller resolution.

Here are all the routes that concern the current context :

routes.MapRoute("Route1",

"Admin/Product/{action}/{id}",

new { controller = "Product", action = "Index", area = "Admin", id = UrlParameter.Optional },

new[] { "Plugin.Controllers" }

)

routes.MapRoute(

"Admin_default",

"Admin/{controller}/{action}/{id}",

new { controller = "Home", action = "Index", area = "Admin", id = "" },

new[] { "Admin.Controllers" }

);

routes.MapRoute(

"Default", // Route name

"{controller}/{action}/{id}", // URL with parameters

new { controller = "Home", action = "Index", id = UrlParameter.Optional },

new[] { "Public.Controllers" }

);

There are 3 ProductController classes in the entire solution :

Plugin.Controllers.ProductController (inherits from the Admin one)

Admin.Controllers.ProductController

Public.Controllers.ProductController

In my view "/Views/Home/Index.cshtml" (i.e. the "Index" action of the HomeController without any area) I have the following code :

@Html.Action("HomepageProducts", "Product")

It refers to the action "HomepageProducts" of the Public.Controllers.ProductController.

MVC looks for the plugin controller instead of the public one and throws the following exception :

[HttpException (0x80004005): A public action method 'HomepageProducts' was not found on controller 'Plugin.Controllers.ProductController'.]

If this helps, the solution use Autofac.MVC5...

Any help/comment/idea is welcome.

Am I missing something or only the routes are implied in controllers resolution ?

UPDATE

When browsing the "Admin" area all actions are well performed, the plugin and the admin controllers works fine.

If I comment the plugin route, the error is not thrown anymore. Of course my plugin controller is not called anymore.

// routes.MapRoute("Route1",

// "Admin/Product/{action}/{id}",

// new { controller = "Product", action = "Index", area = "Admin", id = UrlParameter.Optional },

// new[] { "Plugin.Controllers" }

// )

So I guess the issue is due to the plugin route, the plugin controller itself or the way the route is resolved by MVC ?

UPDATE 2

I tried to uncomment all my routes and specify area in @Html.Action() as follow:

@Html.Action("HomepageProducts", "Product", new { area = "" })

But MVC ignore the area and try to load the Plugin controller...

[HttpException (0x80004005): A public action method 'HomepageProducts' was not found on controller 'Plugin.Controllers.ProductController'.]
