本文实例讲述了 MVC4中使用Html.DropDownListFor的方法。分享给大家供大家参考，具体如下：
一、控制器部分：
public ActionResult PageDetail()
{
var thisList = _sysDepartmentBll.GetAllDepartmentList();//数据源
//添加一条默认数据
var resultList = new List
{
new SelectListItem {Text = "--请选择--", Selected = true, Value = ""}
};
//将数据源添加到resultList集合中
resultList.AddRange(thisList.Select(thisModel => new SelectListItem
{
Text = thisModel.DepartmentName,
Selected = false,
Value = thisModel.DepartmentId
}));
ViewBag.DepartmentList= GetDepartmentSelectList(_sysDepartmentBll.GetAllDepartmentList());
return View();
}
二、PageDetail.cshtml部分
@Html.DropDownListFor(m => m.DepartmentId, ViewBag.DepartmentList as IEnumerable, new { id = "ddlDepartment"})
或者：
@Html.DropDownListFor(m => m.DepartmentId, (List)ViewBag.DepartmentList, new { id = "ddlDepartment"})
希望本文所述对大家程序设计有所帮助。
