RedirectToAction alternative - asp.net

Question

I'm using ASP.NET MVC 3.
I've wriiten a helper class as follows:
public static string NewsList(this UrlHelper helper)
{
return helper.Action("List", "News");
}
And in my controller code I use it like this:
return RedirectToAction(Url.NewsList());
So after the redirect the link looks like this:
../News/News/List
Is there an alternative to RedirectToAction? Is there a better way that I need to implement my helper method NewsList?

Answer 1

Actually you don't really need a helper:
return RedirectToAction("List", "News");
or if you want to avoid hardcoding:
public static object NewsList(this UrlHelper helper)
{
return new { action = "List", controller = "News" };
}
and then:
return RedirectToRoute(Url.NewsList());
or another possibility is to use MVCContrib which allows you to write the following (personally that's what I like and use):
return this.RedirectToAction<NewsController>(x => x.List());
or yet another possibility is to use T4 templates.
So it's up to you to choose and play.
UPDATE:
public static class ControllerExtensions
{
public static RedirectToRouteResult RedirectToNewsList(this Controller controller)
{
return controller.RedirectToAction<NewsController>(x => x.List());
}
}
and then:
public ActionResult Foo()
{
return this.RedirectToNewsList();
}
UPDATE 2:
Example of unit test for the NewsList extension method:
[TestMethod]
public void NewsList_Should_Construct_Route_Values_For_The_List_Action_On_The_News_Controller()
{
// act
var actual = UrlExtensions.NewsList(null);
// assert
var routes = new RouteValueDictionary(actual);
Assert.AreEqual("List", routes["action"]);
Assert.AreEqual("News", routes["controller"]);
}
