Answer 1

MVC does not uses ViewState. it don’t have server side controls to retain the state.

but you can use ViewBag, ViewData to store the values and use it in your views.

public ActionResult Index()
{
    var someList= new List<string>
    {
        "C#, 
        "Java", 
        "PHP"
    };

    ViewData["Languages"] = someList;

    return View();
}

in your view

<ul>
@foreach (var lang in (List<string>)ViewData["Languages"])
{
    <li>
        @lang 
    </li>
}
</ul>
