How to do products sorting? - asp.net-mvc

Question

I need to make a food ordering site for a university graduation project and I have no previous experience in the subject. I did most of the site, but I want to sort with the blue buttons in the menu, but I couldn't do it. I created #Html.ActionLink Name and Price links to try it but it doesn't work. That's why I couldn't assign tasks to the blue buttons. Alphabetically, best seller, price ascending, price descending. Can you help me?
Controller
```
public class MenuController : Controller
{
// GET: Menu
Context c = new Context();
public ActionResult Index(string sortBy)
{
ViewBag.SortNameParameter = string.IsNullOrEmpty(sortBy) ? "Name desc" : "";
ViewBag.SortPriceParameter = sortBy == "Price" ? "Price desc" : "Price";
var uruns = c.Uruns.AsQueryable();
switch(sortBy)
{
case "Name desc":
uruns = uruns.OrderByDescending(x => x.UrunAdi);
break;
case "Price desc":
uruns = uruns.OrderByDescending(x => x.UrunFiyat);
break;
case "Price":
uruns = uruns.OrderBy(x => x.UrunFiyat);
break;
default:
uruns = uruns.OrderBy(x => x.UrunAdi);
break;
}
Context _db = new Context();
Menu vm = new Menu();
//vm.Deger1 = (_db.Uruns.Where(i=>i.Durum)&&_db.Kategoris.Where(i=>i.Durum)).ToList();
vm.Deger1 = _db.Uruns.Where(i=>i.Durum).ToList();
vm.Deger2 = _db.Kategoris.Where(i=>i.Durum).ToList();
return View(vm);
}
