C#实现获取枚举的描述

一个通用获取枚举的描述的方法

/// <summary>
        /// 获取枚举的描述
        /// </summary>
        /// <param name="en">枚举</param>
        /// <returns>返回枚举的描述</returns>
        public static string GetDescription(Enum en)
        {
            Type type = en.GetType();   //获取类型
            MemberInfo[] memberInfos = type.GetMember(en.ToString());   //获取成员
            if (memberInfos!=null&&memberInfos.Length>0)
            {
                DescriptionAttribute[] attrs = memberInfos[0].GetCustomAttributes(typeof(DescriptionAttribute), false) as DescriptionAttribute[];   //获取描述特性

                if (attrs!=null&&attrs.Length>0)
                {
                    return attrs[0].Description;    //返回当前描述
                }
            }
            return en.ToString();
        }

示例：

/// <summary>
    /// 上传状态
    /// </summary>
    public enum UploadState
    {
        [Description("上传失败")]
        UploadFailed = -1,

        [Description("正在上传")]
        Uploading = 0,

        [Description("上传成功")]
        UploadSuccess = 1
    }

调用代码：

EnumService.GetDescription(UploadState.UploadSuccess)
