Question

我希望我的ASP.NET MVC应用程序默认重定向到Product controller index action。所以我将RouteConfig改为

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

            routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

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

但我仍然收到错误

The view 'Index' or its master was not found or no view engine supports the searched locations. 
The following locations were searched: 
~/Views/Home/Index.aspx 
~/Views/Home/Index.ascx 
~/Views/Shared/Index.aspx 
~/Views/Shared/Index.ascx 
~/Views/Home/Index.cshtml 
~/Views/Home/Index.vbhtml 
~/Views/Shared/Index.cshtml 
~/Views/Shared/Index.vbhtml

我调试了应用程序并检查了第三条路径的默认值部分。但它仍然说

{[controller, Home]} 谁能告诉我为什么？

试试这个，它对我有用确保默认路由位于列出的路由表的 BOTTOM 。对于ASP.NET MVC路由表，顺序很重要。

 routes.MapRoute(
                  "Default",
                  "{id}",
                  new { controller = "Product", action = "Index", id = UrlParameter.Optional }
              );

还要检查this tool它对您有帮助

Answer 2

您尚未为Product Controller添加任何视图。为它添加视图，它将按预期工作。

Answer 3

试试这个，它会覆盖默认路线并改为使用你的路线。

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

        routes.MapRoute(
            "DefaultApi", // Route name
            "{Controller}/{action}/{id}", // URL with parameters
            new { controller = "Product", action = "Index", id = UrlParameter.Optional } // Parameter defaults
        );

        routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Home", action = "Index", id = UrlParameter.Optional }// Parameter defaults
        );
    }

ASP.NET MVC更改默认路由
