How to get string url out of registered route in asp.net mvc?

Question

In Global.asax we register routes using:

MapRoute(this System.Web.Routing.RouteCollection routes, 
    string name, 
    string url, 
    object defaults, 
    string[] namespaces)

Is there a way to retrieve the string url from code? Specifically, I am interested in getting route segments from the urls for registered routes like this:

"customRoutePrefix/{controller}/{action}/{id}"

I need to look up "customRoutePrefix" or the equivalent for any registered routes.

I thought I might be able to use System.Web.Routing.RouteTable.Routes to do this, but I haven't found it in there.

Is this possible / how should I do this?

Yes.

You can use:

this.RouteData.Values["segment name"]

For example,

this.RouteData.Values["controller"];

This piece of code will do the trick to retrieve all the registered routes URL's

var res = new List<string>();

foreach (var item in RouteTable.Routes)
{
    var r = (Route)item;

    res.Add(r.Url);
}

this.ViewBag.Res = res;

In your view:

@foreach (var item in this.ViewBag.Res)
{
    <div>@item</div>
}

Results:

Chapter14/{controller}/{action}/{id}
Movies/{controller}/{action}/{id}
api/{controller}/{id}
{resource}.axd/{*pathInfo}
{resource}.svc/{*pathInfo}
{controller}/{action}/{id}
wcf/{*pathInfo}

For the case "customUnknownPrefix/{controller}/{action}/{id}" how would I access the first segment? In this case the value I'm looking for would be "customUnknownPrefix" but it could be anything that gets registered.

Well since that part is not a part of the route values, instead it's a static segment probably your best shot is by inspecting the this.Request.RawUrl or this.Request.Url.Segments

It is part of the route Url that was defined when I registered the route using MapRoute(). My question is how I would get the list of all route urls from the registered routes. this.Request.RawUrl and this.Request.Url.Segments will only return values for the current url... not all of the registered routes. I need to be able to get this list of urls without a request.
