我定义了以下路由：
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(name: "Homepage",url: "",defaults: new { controller = "Restaurants",action = "Search" });
routes.MapRoute(name: "About",url: "about",defaults: new { controller = "Home",action = "About" });
routes.MapRoute(name: "Disclaimer",url: "disclaimer",action = "Disclaimer" });
routes.MapRoute(name: "Contact",url: "contact",action = "Contact" });
routes.MapRoute(name: "RestaurantDetails",url: "{id}/{slug}",defaults: new { controller = "Restaurant",action = "Details" });
routes.MapRoute(name: "RestaurantLocationDetails",url: "{id}/{restaurantSlug}/{locationSlug}",action = "LocationDetails" });
routes.MapRoute(name: "Api",url: "api/{action}",defaults: new { controller = "Api" });
}
我发现一些路由给了一个404，所以我安装了RouteDebugger NuGet包。@H_404_5@
它显示了我对前四个路线的期望，但是在最后3条路线上，我仍然得到一个404，并且路由调试器不会显示在页面的底部 – 我希望它会显示哪些位被映射，但是我什么都没有所有的意见都存在。@H_404_5@
所以我假设我在路线定义上犯了一个错误 – 任何人都可以看出这一点吗？另外，如何获取Route Debugger来告诉我如何将URL映射到返回404的页面的路由字典？@H_404_5@
解决方法
您需要更改路线的顺序。
routes.MapRoute(name: "Homepage",action = "Search" });
routes.MapRoute(name: "About",action = "About" });
routes.MapRoute(name: "Disclaimer",action = "Disclaimer" });
routes.MapRoute(name: "Contact",action = "Contact" });
routes.MapRoute(name: "Api",defaults: new { controller = "Api" });
routes.MapRoute(name: "RestaurantLocationDetails",action = "LocationDetails" });
routes.MapRoute(name: "RestaurantDetails",action = "Details" });
例如：api / action也匹配了RestaurantDetails路由，因为route url参数中只有两个参数。@H_404_5@
所以需要从具体到一般。一般来说，如果在两个路由定义中具有相同数量的参数，则添加的第一个路由将是所选择的路由。@H_404_5@
