路由，RouteData为空

Question

我正在尝试注册2条路由。

一个在/上，另一个在/details/{username}上

在我的RouteConfig.cs中，我尝试了：

public static void RegisterRoutes(RouteCollection routes)
{
    var settings = new FriendlyUrlSettings();
    settings.AutoRedirectMode = RedirectMode.Permanent;
    routes.EnableFriendlyUrls(settings);

    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.MapRoute(
            name: "Details",
            url: "details/{username}",
            defaults: new { action = "Details", username = "" }
        );

    routes.MapRoute(
            name: "Default",
            url: "{controleur}",
            defaults: new { action = "Index"}
        ); 
}

在我的Details.aspx.cs中，我有：

public partial class _Details : Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        var b = RouteData.Values.Keys.Count;
    }
}

但是，我无法在RouteData中获得username值。

这就是如何为MVC-projects映射路由。您似乎正在使用Web表单。下面是如何为Web表单映射路由的方法：

routes.MapPageRoute("Details", 
                    "details/{username}", 
                    "Details.aspx", 
                    false, 
                    new RouteValueDictionary {{"action", "Details"}, {"username", ""}});
