How to generate a path/url from a Route in the Rou

问题:

I have an ASP.NET MVC web application, and I've registered a number of routes in my Global.asax.

I would like to know how I can programmatically build (generate a string url) any one of those registered routes from within my Controller.

I did the same thing in Web Forms with .NET 4.0 using Page.GetRouteUrl(routeName, routeParams) but can't figure out how to do the same thing in MVC (I'm an MVC newbie).

You could use the UrlHelper class inside your controller action.

public ActionResult Index()
{
    string address = Url.RouteUrl(new { 
        action = "foo", controller = "bar", id = "123" 
    });
    // TODO: do something with the url

    return View();
}
