如何在 ASP.NET MVC 的控制器中获取路由名称? [英] How can I get the route name in controller in ASP.NET MVC?

问题描述

ASP.NET MVC 路由在映射时具有名称:

ASP.NET MVC routes have names when mapped:

routes.MapRoute(
    "Debug", // Route name -- how can I use this later????
    "debug/{controller}/{action}/{id}",
    new { controller = "Home", action = "Index", id = string.Empty } );

有没有办法获取路线名称，例如上面例子中的调试"?我想在控制器的 OnActionExecuting 中访问它，以便我可以在调试时在 ViewData 中设置内容，例如，通过在 URL 前加上/debug/...

Is there a way to get the route name, e.g. "Debug" in the above example? I'd like to access it in the controller's OnActionExecuting so that I can set up stuff in the ViewData when debugging, for example, by prefixing a URL with /debug/...

推荐答案

遗憾的是，路由名称未存储在路由中.它只是在 MVC 内部用作集合中的键.我认为这是您在使用 HtmlHelper.RouteLink 创建链接时仍然可以使用的东西(例如，也许在其他地方也是如此，不知道).

The route name is not stored in the route unfortunately. It is just used internally in MVC as a key in a collection. I think this is something you can still use when creating links with HtmlHelper.RouteLink for example (maybe somewhere else too, no idea).

无论如何，我也需要它，这就是我所做的:

Anyway, I needed that too and here is what I did:

public static class RouteCollectionExtensions
{
    public static Route MapRouteWithName(this RouteCollection routes,
    string name, string url, object defaults, object constraints)
    {
        Route route = routes.MapRoute(name, url, defaults, constraints);
        route.DataTokens = new RouteValueDictionary();
        route.DataTokens.Add("RouteName", name);

        return route;
    }
}

所以我可以注册一个这样的路由:

So I could register a route like this:

routes.MapRouteWithName(
    "myRouteName",
    "{controller}/{action}/{username}",
    new { controller = "Home", action = "List" }
    );

在我的控制器操作中，我可以通过以下方式访问路由名称:

In my Controller action, I can access the route name with:

RouteData.DataTokens["RouteName"]
