Alternatively you can do as explained in Microsoft MSDN.

public class PersonController : Controller
{
    static List<Person> people = new List<Person>();

    //
    // GET: /Person/
    public ActionResult Index()
    {
        return View(people);
    }

    //
    // GET: /Person/Details/5
    public ActionResult Details(Person person)
    {
        return View(person);
    }

    //
    // GET: /Person/Create
    public ActionResult Create()
    {
        return View();
    } 

    //
    // POST: /Person/Create
    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Create(Person person)
    {
        if (!ModelState.IsValid)
        {
            return View("Create", person);
        }

        people.Add(person);

        return RedirectToAction("Index");
    }
}
