How do I use the DropDownList in ASP.NET MVC 3 -

i new mvc , trying populate dropdownlist in view list of 'rules' controller. when way listed, dropdownlist bunch of items cellularautomata.models.rules. know doing incorrectly, i'm wondering how show rule description each rule in dropdownlist.

i have model

public class rule {     public int id { get; set; }     public int name { get; set; }     public string description{ get; set; }      public rule(int name, string description)     {         name = name;         description = description;      }     public rule()     {         name = 0;         description = "";     } } 

a controller

    public actionresult index()     {         var rules = rule in db.rules                     select rule;          return view(rules.tolist());     } 

and view

@model ienumerable<cellularautomata.models.rule>  @{     viewbag.title = "index"; } <h2>index</h2>  <table>     <tr>         <td>             @html.dropdownlist("test", new selectlist(model))         </td>     </tr> </table> 

you have view model:

public class myviewmodel {     public string selectedruleid { get; set; }     public ienumerable<rule> rules { get; set; } } 

and in controller:

public actionresult index() {     var model = new myviewmodel     {         rules = db.rules     };     return view(model); } 

and in view:

@model cellularautomata.models.myviewmodel @{     viewbag.title = "index"; } <h2>index</h2>  @html.dropdownlistfor(     x => x.selectedruleid,      new selectlist(model.rules, "id", "description") )
