asp.net-mvc - MVC Controller 操作参数为空

我有 Controller 名称:District和Action名称:Incharges但我希望URL像这样(带有某些参数的操作名称)

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，在action参数中始终将其返回为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，在action参数中始终将其返回为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";
}

<h2>Index About</h2>

最佳答案

您必须先声明的特定路线

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 }
            ););
