ASP.NET MVC: how to parse url string to get RouteData [duplicate]

This question already has answers here: How to get RouteData by URL? (2 answers) Closed 8 years ago.

Is there any way to get RouteData from a url string?

I have login form with returlUrl as query string parameter. My routes are defined as开发者_运维技巧 : {languageCode}/{controller}/{action}

In action method LogIn(string returlUrl) the returlUrl is something like "en/home/contacts" etc. I need to change languagePart a i dont want to use string.Replace, as routes may change in future.

Thank you.

So this is an old thread obviously, but for anyone else coming to this question via Google, I just wrote a blog post about a way to do this pretty easily. I actually came across this question on SO when I was attempting to find a way to do this myself but I didn't find one that I liked so I wrote my own.

This is the best option I can think of off the top of my head. Bascially, using RouteTable.Routes.GetRouteData and Mocking HttpContextBase based on your Url string.
