枚举中文转换为英文及调用

1.枚举

/// <summary>
        /// 语言类别
        /// </summary>
        public enum LanguageType
        {
            [Description("所有语言")]
            All = 0,

            [Description("中文")]
            cn = 1,

            [Description("英文")]
            en = 2,

            [Description("印度斯坦语")]
            Hindustani = 3,

            [Description("西班牙语")]
            Spanish = 4,

            [Description("俄语")]
            Russian = 5,

            [Description("阿拉伯语")]
            Arabic = 6,

            [Description("孟加拉语")]
            Bengali = 7,

            [Description("葡萄牙语")]
            Portuguese = 8,

            [Description("马来-印尼语")]
            MalayIndonesian = 9,

            [Description("法语")]
            French = 10,

            [Description("日语")]

            [Description("韩语")]
            Korean = 12
        }

2.方法

public class EnumHelp
    {
        public static string GetDescription(Enum obj)
        {
            string objName = obj.ToString();

            return arrDesc[0].Description;
        }

        /// <summary>
        /// 获取枚举值的详细文本

            Type t = e.GetType();
            foreach (System.Reflection.FieldInfo f in ms)

                if (f.Name != e.ToString()) continue;

                //反射出自定义属性
                foreach (Attribute attr in f.GetCustomAttributes(true))
                {
                    //类型转换找到一个Description，用Description作为成员名称
                    System.ComponentModel.DescriptionAttribute dscript = attr as System.ComponentModel.DescriptionAttribute;
                    if (dscript != null)
                        return dscript.Description;
                }

            }

            //如果没有检测到合适的注释，则用默认名称
            return e.ToString();
        }

            FieldInfo[] fieldinfos = enumType.GetFields();
            foreach (FieldInfo field in fieldinfos)
            {
                if (field.FieldType.IsEnum)
                {
                    Object[] objs = field.GetCustomAttributes(typeof(DescriptionAttribute), false);

                    dic.Add(field.Name, ((DescriptionAttribute)objs[0]).Description);
                }

            }

            return dic;
        }

        ///<returns>键值对</returns>
        public static NameValueCollection GetNVCFromEnumValue(Type enumType)
        {
            NameValueCollection nvc = new NameValueCollection();
            Type typeDescription = typeof(DescriptionAttribute);
            System.Reflection.FieldInfo[] fields = enumType.GetFields();
            string strText = string.Empty;
            string strValue = string.Empty;
            foreach (FieldInfo field in fields)
            {
                if (field.FieldType.IsEnum)
                {
                    strValue = ((int)enumType.InvokeMember(field.Name, BindingFlags.GetField, null, null, null)).ToString();
                    object[] arr = field.GetCustomAttributes(typeDescription, true);

3.调用

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