枚举定义，获取枚举的描述

定义枚举熟悉，描述

    /// <summary>
    /// 枚举注释的自定义属性类
    /// </summary>
    public class EnumDescriptionAttribute : Attribute
    {
        private string m_strDescription;
        public EnumDescriptionAttribute(string strPrinterName)
        {
            m_strDescription = strPrinterName;
        }

        public string Description
        {
            get { return m_strDescription; }
        }
    } 

　　

定义枚举

    /// <summary>
    /// 日志登记区分
    /// </summary>
    public enum LogLevel
    {
        /// <summary>
        /// 默认
        /// </summary>
        [EnumDescription("正常")]
        Default = 0,
        /// <summary>
        /// 提醒
        /// </summary>
        [EnumDescription("提醒")]
        Remind = 1,
        /// <summary>
        /// 崩溃
        /// </summary>
        [EnumDescription("崩溃")]
        collapse = 2
    }

 

获取枚举的描述

 

        /// <summary>
        /// 获取枚举的描述信息
        /// </summary>
        /// <typeparam name="T">枚举类型</typeparam>
        /// <param name="enums">枚举</param>
        /// <returns>枚举的描述，不存在则返回枚举的值</returns>
        public string GetEnumDescription<T>(object enums)
        {

            string RtnMsg = string.Empty;
            Dictionary<string, int> enumDic = new Dictionary<string, int>();
            Type t = typeof(T);
            Array arrays = Enum.GetValues(t);
            for (int i = 0; i < arrays.LongLength; i++)
            {
                T test = (T)arrays.GetValue(i);

                if (test.ToString() == enums.ToString())
                {
                    try
                    {
                        FieldInfo fieldInfo = test.GetType().GetField(test.ToString());
                        object[] attribArray = fieldInfo.GetCustomAttributes(false);
                        EnumDescriptionAttribute attrib = (EnumDescriptionAttribute)attribArray[0];
                        enumDic.Add(attrib.Description, DataConvert.GetValInt(test));

                        RtnMsg= attrib.Description;
                    }
                    catch (Exception)
                    {
                        RtnMsg = test.ToString();
                    }
                }
            }


            return RtnMsg;
        }
