@using (Html.BeginForm("redirectObject", "Collection", Model.myFriendList))
{ <h2>Transfer</h2>
 
@Html.ListBoxFor(s=>s.myFriendList, new SelectList(Model.myFriendList))
    
  <button  type="submit" value="test" name="btnSubmit"></button>
  }

 public class CollectionController : Controller
    {
        //
        // GET: /Collection/

        public ActionResult Index()
        {
            TestString MyListBoxFriends = new TestString();
            List<string> friends = new List<string>();
            friends.Add("Himanshu");
friends.Add("Sumit");
friends.Add("Jo"); 
friends.Add("Waan");
            MyListBoxFriends.myFriendList = friends;
            return View("Transfer", MyListBoxFriends);
        }
        [HttpPost]
        public ActionResult redirectObject(TestString cc)
        {
            var yourFriendList = cc.myFriendList;
            return View("YourView");
        }
    }
//this is model class which is bind to view
    public class TestString
    {
        public List<string> myFriendList { get; set; }
    } 
}
