c# - 选择单选按钮枚举？

Question

Hi I have a model that contains an enum called activitylevel and also a property called activityselected, I have a table of radiobuttons that are bound to the activityselected property, when a radiobutton is select I want to pass the corresponding enum to the activityselected property, in我的观点是“当前上下文中不存在 ActivityLevel”？只是想知道我出错了还是有更好的方法？谢谢您的帮助！！

模型：

  public class UserStats
    {
        public enum ActivityLevel
        {
            Sedentary,
            LightActivity,
            Moderate,
            Active,
            Extra
        }

        public Enum ActivitySelected { get; set; }

        [Key]
        public int UserID { get; set; }

看法：

      <table>
       <tr>
    <td>
        @Html.RadioButtonFor(model => model.ActivitySelected, ActivityLevel.Sedentary) Sedentary
    </td>
</tr>
<tr>
    <td>
        @Html.RadioButtonFor(model => model.ActivitySelected,ActivityLevel.LightActivity) Light Activity
    </td>
</tr>    
<tr>
    <td>
        @Html.RadioButtonFor(model => model.ActivitySelected, ActivityLevel.Moderate) Moderate
    </td>
</tr>
            <tr>
         <td>
        @Html.RadioButtonFor(model => model.ActivitySelected,ActivityLevel.Active) Active
    </td>
</tr>    
<tr>
    <td>
        @Html.RadioButtonFor(model => model.ActivitySelected, ActivityLevel.Extra) Extra
    </td>
</tr>
    </table>

枚举在 UserStats 类中声明，因此您必须引用它UserStats.ActivityLevel.XXX或将枚举移出类（这是我推荐的）

此外，我将通过其真实类型名称声明枚举成员，而不是类型 Enum：

public enum ActivityLevel
{
   Sedentary,
   LightActivity,
   Moderate,
   Active,
   Extra
}

public class UserStats
{

    public ActivityLevel ActivitySelected { get; set; }

    [Key]
    public int UserID { get; set; }
