There are a few ways of display DropDownList in MVC. Here is my way.

Note: You need a collection of SelectListItem in model.

Model

public class MyModel
{
    public int SelectedId { get; set; }
    public IList AllItems { get; set; }

    public MyModel()
    {
        AllItems = new List();
    }
}

Controller

public class HomeController : Controller
{
    public ActionResult Index()
    {
        var model = new MyModel();
        model.AllItems = new List
        {
            new SelectListItem { Text = "One",  Value = "1"},
            new SelectListItem { Text = "Two",  Value = "2"},
            new SelectListItem { Text = "Three",  Value = "3"}
        };
        return View(model);
    }

    [HttpPost]
    public ActionResult Index(MyModel model)
    {
        // Get the selected value
        int id = model.SelectedId;
        return View();
    }
}

View

@model DemoMvc.Controllers.MyModel
@using (Html.BeginForm("Index", "Home", FormMethod.Post))
{
    @Html.DropDownListFor(x => x.SelectedId, Model.AllItems)
    
}
