Add the SelectList to your model:

public SelectList DropDownList { get; set; }

build the class for that collection:

public class MyListTable
{
    public string Key { get; set; }
    public string Display { get; set; }
}

and then in your controller, load the data for the MyListTable class from the database:

var list = new List();

using (SqlConnection c = new SqlConnection(cString))
using (SqlCommand cmd = new SqlCommand("SELECT KeyField, DisplayField FROM Table", c))
{
    using (SqlDataReader rdr = cmd.ExecuteReader())
    {
        while (rdr.Read())
        {
            list.Add(new MyListTable
            {
                Key = rdr.GetString(0),
                Display = rdr.GetString(1)
            });
        }
    }
}

var model = new users();
model.DropDownList = new SelectList(list, "Key", "Display");

and then finally, you need to send your model to the view:

return View(model);

Now in the Razor you can display this:

@Html.DropDownListFor(m => Model.DropDownList);

You of course can name these things better names, but you get the idea.
