Get ID from URL in an action from a controller with ASP .NET?

Question

I work asp.net MVC, I call an action (let's call it MyAction) from MyController while I'm at the following url www.mywebapp.com/MyController/AnotherAction/123

I need to get the 123 in MyAction, so I started to do something like this :

var url = Request.Url;

In order to parse it then get the ID.

But I'm not sure if it's the "best" way to do it. Do you know how can I get the ID from the current URL when I am in MyAction properly and safely ?

Solution

You can get this from the RouteData:

var url = Url.RequestContext.RouteData.Values["id"];
