MVC RouteConfig，路由确定控制器

Question

我想访问我的主要页面(索引、关于、联系...)仅限{action}{id}，但对其他{controller}{action}{id}。例如：

A principal page: myweb.com/index
No principal page: myweb.com/Account/Login

我找过了，但我不知道具体是怎么做的。

这是我的RouteConfig

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

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

        /*routes.MapRoute(
            "Account",
        "Account/{AccountId}",
        new { action = "Index", controller = "Course" }
        );*/

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

        /*routes.MapRoute(
        "Account",
        "Account/{courseId}",
            //new { action = "Index", controller = "Course" }
        new { controller = "Home", action = "Index" }
        );*/
        //routes.Add()
    }
}

请参考示例：

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        // Principal pages have unique route per each page.
        // Methods About and Contact should be implemented in HomeController.
        routes.MapRoute(
            name: "About",
            url: "about",
            defaults: new { controller = "Home", action = "About" }
        );

        routes.MapRoute(
            name: "Contact",
            url: "contact",
            defaults: new { controller = "Home", action = "Contact" }
        );

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

如下所示更改您的路由配置，但是您必须将所有主要操作都放在一个控制器中，比如PrincipalController，因为您的路由中不会有控制器。

始终将高优先级路由映射到低优先级路由之前。

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Principal",
            url: "{action}/{id}",
            defaults: new { controller = Princpal", action = "Index", id = UrlParameter.Optional }

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