通过枚举的集合ASP.NET MVC ActionMethod [英] Pass collection of enums to ASP.NET MVC ActionMethod

问题描述

有没有办法来枚举集合传递给ActionMethod（在GET）自动？

例如，如果我有以下枚举定义：

 枚举DaysEnum {周六，周日，周一，周二，周三，周四，周五};
 

和我有一个ActionMethod定义：

 的ActionResult SampleActionMethod（列表＆LT; D​​aysEnum＆GT;天）
 

有没有一种方法，我可以呈现，在视图中，将通过DayEnums集合中的URL。是这样的：

  VAR日子她念叨=新的List＆LT; D​​aysEnum＆GT; {DaysEnum.Sat，DaysEnum.Sun，DaysEnum.Mon};Url.Route（新{天=日子她念叨着，控制器=无所谓，行动=SampleActionMethod}）;
 

默认模型联似乎并不支持这一点，因为我目前得到以下渲染：

  HTTP：//.../System.Collections.Generic.List`1 [DaysEnum]
 

我知道我可以通过手动压扁集合，也就是说，一个破折号deliniated串做到这一点，然后重新在ActionMethod收集，但我一直在寻找的东西更优雅。各种博客 <一个href=\"http://www.hanselman.com/blog/ASPNETWireFormatForModelBindingToArraysListsCollectionsDictionaries.aspx\"相对=nofollow>帖子谈论传入的集合，但更多的是在做岗位时。

解决方案

 ＆LT;％= Html.ActionLink（测试枚举，SampleActionMethod，新RouteValueDictionary {
    {天[0]，DaysEnum.Sun}，{天[1]，DaysEnum.Mon}
}）％GT;
 

Is there a way to pass a collection of Enums to an ActionMethod (on a GET) automatically?

For example, if I have the following enum definition:

enum DaysEnum {Sat, Sun, Mon, Tue, Wed, Thu, Fri};

and, I have an ActionMethod definition of:

ActionResult SampleActionMethod ( List<DaysEnum> days)

Is there a way I could render, in a View, a URL that would pass in a collection of DayEnums. Something like:

var someDays = new List<DaysEnum> {DaysEnum.Sat, DaysEnum.Sun, DaysEnum.Mon};

Url.Route(new { days = someDays, controller="whatever", action="SampleActionMethod"});

The default model binder doesn't seem to support this, since I'm currently getting the following rendered:

http://.../System.Collections.Generic.List`1[DaysEnum]

I know I can do this by manually flattening the collection to, say, a dash-deliniated string, and then recreate the collection in the ActionMethod, but I was looking at something more elegant. Various blog posts talk about passing in collections, but that is more about when doing POSTS.

解决方案

<%= Html.ActionLink("test enums", "SampleActionMethod", new RouteValueDictionary { 
    { "days[0]", DaysEnum.Sun }, { "days[1]", DaysEnum.Mon } 
}) %>
