创建模型：

public class myViewModel{
    public int selectedIndex { get; set; } //one for selected index
    public List<myItemsModel> mylist { get; set; } // one for list
}

填充模型：

public ActionResult myView() {
    myViewModel model = new myViewModel();
    model.selectedIndex  = aninteger;
    model.mylist = (from blah in blahblah .....);
    return View(model);
}

在您看来：

//Bind the model
@model myProject.Models.myViewModel

//Bind the 2 view models to the control
@Html.DropDownListFor(x => x.selectedIndex , new SelectList(Model.mylist, "id", "dt", Model.selectedIndex), "Placeholder", new { onchange = @"this.form.submit();", @class = "your css class" })
