I\'m trying to get the current Route into my navigation controller so I can run comparisons as the navigation menu data is populated.

My Links object is like this:

You don't need to pass route data to a controller because the controller already has knowledge of it via the RouteData property:

public ActionResult Index() {
    // You could use this.RouteData here
    ...
}

Now if you want to pass some simple arguments like current action that was used to render the view you could do this:

<%= Html.RenderAction(
    "MenuOfStreamEntries",
    "Nav",
    new {
        currentStreamUrl = "Blog", 
        currentAction = ViewContext.RouteData.Values["action"],
        currentController = ViewContext.RouteData.Values["controller"]
    }
); %>

And in your controller:

public ActionResult Nav(string currentAction, string currentController) 
{
    ...
}
