ABP 自动本地化枚举

TagHelpers：select

  1. protected virtual List<SelectListItem> GetSelectItemsFromEnum(TagHelperContext context, TagHelperOutput output, ModelExplorer explorer)

框架代码：

  1. public static class EnumHelper
  2. {
  3.     public static string GetLocalizedMemberName(Type enumType, object value, IStringLocalizerFactory stringLocalizerFactory)
  4.     {
  5.         var memberName = enumType.GetEnumName(value);
  6.         var localizedMemberName = AbpInternalLocalizationHelper.LocalizeWithFallback(
  7.             new[]
  8.             {
  9.                     stringLocalizerFactory.CreateDefaultOrNull()
  10.             },
  11.             new[]
  12.             {
  13.                     $"Enum:{enumType.Name}.{memberName}",
  14.                     $"{enumType.Name}.{memberName}",
  15.                     memberName
  16.             },
