ASP.NET MVC 4子类中未命中路由

为什么第一条路线要跳过第二条路线？第一个路由具有第二个路由的基本控制器类，因此小部件继承事件，但我的事件“注册”方法不断受到攻击

Url

Widgets/v1/RegistrationWidget?eventid=3762

路线

routes.MapRouteLowercase(
                "DefaultWidget",
                "widgets/v{version}/{action}widget",
                new { controller = "Widgets", action = "NotFound", version = 1, slug="event" },
                new { version = @"\d+" }
            );

        routes.MapRouteLowercase(
          "NamedEvent",
          "{Id}/{slug}/{action}",
          new { controller = "Event", action = "Index", slug = "event" },
          new { Id = @"\d+" }
        );

小部件控制器

public partial class WidgetsController : EventController
    {
    public virtual ActionResult RegistrationWidget(int version, int? eventId, string slug, int? divisionTeamId = null, int? divisionId = null)
    {
        return GetRegistration(eventId, divisionId, divisionTeamId, new WidgetRegistrationViewModel(version));
    }

public partial class EventController : SiteController
    {
    public virtual ActionResult Registration(int? id, string slug, int? divisionTeamId = null, int? divisionId = null)
    {
        return GetRegistration(id, divisionTeamId, divisionTeamId, new EventRegistrationViewModel());
    }

事件控制器

public partial class WidgetsController : EventController
    {
    public virtual ActionResult RegistrationWidget(int version, int? eventId, string slug, int? divisionTeamId = null, int? divisionId = null)
    {
        return GetRegistration(eventId, divisionId, divisionTeamId, new WidgetRegistrationViewModel(version));
    }

public partial class EventController : SiteController
    {
    public virtual ActionResult Registration(int? id, string slug, int? divisionTeamId = null, int? divisionId = null)
    {
        return GetRegistration(id, divisionTeamId, divisionTeamId, new EventRegistrationViewModel());
    }

根据您的url

Widgets/v1/RegistrationWidget？eventid=3762

操作名称将被计算为

Registration

，而不是您期望的

RegistrationWidget

，因此，mvc实际上使用第一个路由，但将其转发给基类方法。

无论您在花括号之间放置什么，路由引擎都将使用它来尝试并查找您要查找的操作，因为您正在请求RegistrationWidget，并且您的路由设置为{action}widget路由引擎将在WidgetsController类中查找名为Registration的操作。这之前也让我犯了一个错误。

我通过使用共享公共方法的抽象基类解决了这个问题。
