asp.net-mvc - MVC Controller 操作参数为空

Question

我有 Controller 名称:District 和操作名称:Incharges 但我希望 URL 是这样的(带有一些参数的操作名称)

www.example.com/district/incharges/aaa

www.example.com/district/incharges/bbb

www.example.com/district/incharges/ccc

但是，在调试 teamName 时，操作参数中始终返回 NULL。

路由

routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );

            routes.MapRoute(
            "DistrictDetails",
            "District/Incharges/{teamName}",
            new { controller = "District", action = "Incharges" }
            ); 

Controller

但是，在调试 teamName 时，操作参数中始终返回 NULL。

public class DistrictController : Controller
    {     


        public ActionResult Incharges(string teamName)
        {
            InchargePresentationVM INPVM = new InchargePresentationVM();
            INPVM.InitializePath(teamName, string.Empty);
            return View("", INPVM);
        }
}

查看

@{
    ViewBag.Title = "Index";
}

具体路线你要先声明

routes.MapRoute(
            "DistrictDetails",
            "District/Incharges/{teamName}",
            new { controller = "District", action = "Incharges", id = UrlParameter.Optional }

routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            ););
