        RedirectToAc         


        

Answer 1

You need to return RedirectToAction instead of just calling the RedirectToAction method. Also, your method will need to return an ActionResult is a return type compatible with both ViewResult and RedirectToRouteResult.

public ActionResult List() 
{
    IEnumerable<IModel> myList = repository.GetMyList();
    if(1 == myList.Count())
    {
        return RedirectToAction("Edit", new { id = myList.Single().id });
    }

    return View(myList);
}
