下拉Mvc显示默认选择的项目

Question

我是新的MVC，我想问你是否可以教我如何设置/显示下拉列表中的默认项目？

在控制器

..

[HttpGet] 
public ActionResult Edit(int ID) 
{ 
    EmployeeDBEntities o = new EmployeeDBEntities(); 
    Employee e = new Employee(); 
    e = o.Employees.Single(x => x.EMP_ID == ID); 
    ViewBag.Dept = o.uspDeptCbo().Select(x => new SelectListItem { Value = x.DEPT_ID.ToString() , Text=x.DEPARTMENT }); 
    return View(e); 
} 

查看

<div class="editor-field"> 
    @Html.DropDownList("Dept",string.Empty) 
    @Html.ValidationMessageFor(model => model.DEPT_ID) 
</div>
