good day, i want to create a dropdownlist using the htmhelper classes, i'm very new to this and it's already looking confusing.

i have a list of items that i want to add to this dropdown and that list of items are in a generic <list>

List<string> Name = new List<string>();

in my model as shown

i added the items to the list using the getState() method

namespace newNSMS.Areas.Ministries.Models
{
    public class Category
    {
        public List<string> Name = new List<string>();        
    }
    
    public class getMethods
    {
        public static Category getState(Category d)
        {
            try
            {
                string countCode = "Nig";
                char[] chars = { ',' };

                testStealthServ.countries csd = new testStealthServ.countries();
                List<string> sth = csd.getStates(countCode).ToList<string>();
                foreach (var v in sth)
                {
                    string[] splits = v.Split(chars);

                    d.pID += splits.ElementAt(1);
                    d.pName += splits.ElementAt(0);

                    d.Name.Add(splits.ElementAt(0));
                    d.ID.Add(splits.ElementAt(1));
                }

                return d;
            }
            catch (Exception ex)
            {
                throw ex.InnerException;
            }
        }
    }
}

i want the dropdownlist to be populated in my view on page load so i did this in my controller class

public ActionResult MinistriesHome()
{
    Category c = new Category();
    getMethods.getState(c);

    return View(c);
}

how do i connect the list items to the htmlhelper dropdownlist as shown below

<div class="col-sm-10">
    @Html.DropDownList("schlreg", (SelectList)Model => Model.Name, null, new { @class = "Category" })
</div>

i really have no idea what i'm doing in the view. the form name is "schlreg". please assist me on how to populate the view with the model list data.

Thanks
