ASP.NET MVC DropdownList的使用

1：直接使用HTML代码写

<select name="year">

    <option value="2011">2010</option>

    <option value="2012">2011</option>

    <option value="2013">2012</option>

    <option value="2014">2013</option>

</select>

效果：

2：将枚举中的值写入到 DropdownList

假设有个枚举：

 namespace MvcDropdownList.Controllers

 {

     public class EnumController : Controller

     {

         // GET: /Enum/

         private const string ZHOUYI = "语文";

         private const string ZHOUER = "数学";

         private const string ZHOUSAN = "物理";

         private const string ZHOUSI = "化学";

         private const string ZHOUWU = "英语";

         private const string ZHOULIU = "C语言";

         private const string ZHOUQI = "ASP.NE";

         public enum Days

         {

             Monday =,

             Tuesday = ,

             Wednesday = ,

             Thursday = ,

             Friday = ,

             Saturday = ,

             Sunday =

         }

         public static IDictionary<int, string> BindData()

         {

             IDictionary<int, string> dict = new Dictionary<int, string>();

             dict.Add((int)Days.Monday, ZHOUYI);

             dict.Add((int)Days.Tuesday, ZHOUER);

             dict.Add((int)Days.Wednesday, ZHOUSAN);

             dict.Add((int)Days.Thursday, ZHOUSI);

             dict.Add((int)Days.Friday, ZHOUWU);

             dict.Add((int)Days.Saturday, ZHOULIU);

             dict.Add((int)Days.Sunday, ZHOUQI);

             return dict;

         }

         public ActionResult Index2()

         {

             return View();

         }

     }

 }

拓展类：

 namespace MvcDropdownList.Models

 {

     public static class TestExtention

     {

         public static MvcHtmlString DropDownList(this HtmlHelper helper, string name, IDictionary<int,string> dict, string key, string value)

         {

             SelectList selectListItems = new SelectList(dict, key, value);

             return helper.DropDownList(name, selectListItems);

         }

     }

 }

前台：

 <body>

     <div>

         @Html.DropDownList("saaa", MvcDropdownList.Controllers.EnumController.BindData(),"Key","Value")

     </div>

 </body>

注意前台页面需要添加前面两个类的引用：

 @using MvcDropdownList.Models

 @using MvcDropdownList.Controllers;

效果：
