一、非强类型：

Controller:

ViewData["AreId"] = from a in rp.GetArea()

select new SelectListItem {

Text=a.AreaName,

Value=a.AreaId.ToString()

};

View:

@Html.DropDownList("AreId")

还可以给其加上一个默认选项：@Html.DropDownList("AreId", "请选择");

二、强类型：

DropDownListFor常用的是两个参数的重载，第一参数是生成的select的名称，第二个参数是数据，用于将绑定数据源至DropDownListFor

Modle:

public class SettingsViewModel

{

Repository rp =new Repository();

public string ListName { get; set; }

public IEnumerable<SelectListItem> GetSelectList()

{

var selectList = rp.GetArea().Select(a => new SelectListItem {

Text=a.AreaName,

Value=a.AreaId.ToString()

});

return selectList;

}

}

Controller:

public ActionResult Index()

{

return View(new SettingsViewModel());

}

View:

@model Mvc３Applicationtest2.Models.SettingsViewModel

@Html.DropDownListFor(m=>m.ListName,Model.GetSelectList(),"请选择")
