3.调用

1 protected string GetLanguageTypeName(int languageValue) {
2             Dictionary<string,string> dic = EnumHelp.GetEnumDic(typeof(CommonEnum.LanguageType));
3             string name = Enum.GetName(typeof(HX.Common.CommonEnum.LanguageType), languageValue);
4
5             return dic[name];
6         }
