MVC中对Enum中的枚举项应用DisplayTemplates和EditorTemplates

public enum MyEnum : byte
    {
        [Display(Name = "Zéro")]
        Zero,

        [Display(Name = "Un")]
        One,

        [Display(Name = "Duex")]
        Two,

        [Display(Name = "Trois")]
        Three,

        [Display(Name = "Quatre")]
        Four,
    }

@model Enum

@if (EnumHelper.IsValidForEnumHelper(ViewData.ModelMetadata))
{
   // Display Enum using same names (from [Display] attributes) as in editors
   string displayName = null;
   foreach (SelectListItem item in EnumHelper.GetSelectList(ViewData.ModelMetadata, (Enum)Model))
   {
       if (item.Selected)
       {
           displayName = item.Text ?? item.Value;
       }
   }

   // Handle the unexpected case that nothing is selected
   if (String.IsNullOrEmpty(displayName))
   {
       if (Model == null)
       {
           displayName = String.Empty;
       }
       else
       {
           displayName = Model.ToString();
       }
   }
   
   @Html.DisplayTextFor(model => displayName)
}

{
   // This Enum type is not supported.  Fall back to the text.
   @Html.DisplayTextFor(model => model)
}
