    {
        return  new[]
    {
        new SelectListItem { Value = "1", Text = "Science", Selected=true },

        new SelectListItem { Value = "3", Text = "Physics" },
    };
    }
}

推荐答案

试试这个

try this

public static class DropDownList<t>
   {
       public static SelectList LoadItems(IList<t> collection, string value, string text)
       {
           return new SelectList(collection, value, text);
       }
   }
Call the method from the controller like Below.
ViewData["Executives"] =
                DropDownList<executives>.LoadItems(
                    objExecutivesDbContext.Executives.ToList(), "ExecutiveId", "ExecutiveName ");
Call the viewData from the View like below
<div class="editor-field">
            @Html.DropDownListFor(model => model.ExecutiveId, (IEnumerable<selectlistitem>) ViewData["Executives"], "--Select--")

希望这会有所帮助
