.NET枚举类型转为List类型 - 度量快速开发平台-专业、快速的软件定制快开平台

1：定义一个枚举类型

/// <summary>
/// 资源状态
/// </summary>
public enum ResourceState
{
      /// <summary>
      /// 下架
      /// </summary>
      [Description("下架")]
      SoldOut = 0,
      /// <summary>
      /// 上架
      /// </summary>
      [Description("上架")]
      Putaway = 1,

      /// <summary>
      /// 交易成功
      /// </summary>
      [Description("交易成功")]
      Success = 2,

      /// <summary>
      /// 废标
      /// </summary>
      [Description("废标")]
      AbandonedTender = 6,
      /// <summary>
      /// 违约标
      /// </summary>
      [Description("违约标")]
      DefaultMark = 7,

      /// <summary>
      /// 中标
      /// </summary>
      [SetClassification(Type = 5)]
      [Description("中标")]
      WinTheBidding = 3,
      /// <summary>
      /// 流标
      /// </summary>
      [SetClassification(Type = 6)]
      [Description("流标")]
      FlowStandard = 4,
      /// <summary>
      /// 未中标
      /// </summary>
   [SetClassification(Type = 4)]
      [Description("未中标")]
      LoseABid = 5,
      /// <summary>
      /// 竞价中
      /// </summary>
[SetClassification(Type = 2)]
      [Description("竞价中")]
      Bidding = 8,

      /// <summary>
      /// 竞拍中
      /// </summary>
      [SetClassification(Type = 3)]
      [Description("竞拍中")]
      Auctioning = 9,

      /// <summary>
      /// 已处理（针对于流标资源）
      /// </summary>
      [Description("已处理")]
      Alreadyprocessed = 10,

      /// <summary>
      /// 已过期
      /// </summary>
      [Description("已过期")]
      ExpiredTime = 11,

      /// <summary>
      /// 所有报价
      /// </summary>
      [SetClassification(Type = 1)]
      [Description("所有报价")]
      All = 12

2:自定义一个标记类型继承Attribute

/// <summary>
/// 添加自定义属性

/// 作用：过滤枚举类型
/// </summary>
public class SetClassificationAttribute : Attribute
{
      /// <summary>
      /// 分类
      /// </summary>
      public int Type { get; set; }

public SetClassificationAttribute() { }

3：自定义返回List类型

/// <summary>
/// 自定义返回值类型
/// </summary>
public class EnumberCreditType
{
      /// <summary>
      /// 枚举的描述
      /// </summary>
      public string Desction { set; get; }

      /// <summary>
      /// 枚举名称
      /// </summary>
      public string Key { set; get; }

      /// <summary>
      /// 枚举对象的值
      /// </summary>
      public int Value { set; get; }

      /// <summary>
      /// 描述
      /// </summary>
      public string Name { get; set; }

      /// <summary>
      /// 分类
      /// </summary>
      public int Classification { set; get; }
}

4:枚举转为List<EnumberCreditType>方法

      /// <summary>
      /// 获取枚举列表
      /// </summary>
      /// <typeparam name="T"></typeparam>
      /// <returns></returns>
      public static List<EnumberCreditType> EnumToList<T>()
      {
         List<EnumberCreditType> list = new List<EnumberCreditType>();

         foreach (var e in Enum.GetValues(typeof(T)))
         {
            EnumberCreditType m = new EnumberCreditType();
            object[] objArr = e.GetType().GetField(e.ToString()).GetCustomAttributes(typeof(DescriptionAttribute), true);
            if (objArr != null && objArr.Length > 0)
            {
                  DescriptionAttribute da = objArr[0] as DescriptionAttribute;
                  m.Desction = da.Description;
            }
            //SetClassification
            object[] setClassificationArr = e.GetType().GetField(e.ToString()).GetCustomAttributes(typeof(SetClassificationAttribute), true);
            if (setClassificationArr != null && setClassificationArr.Length > 0)
            {
                  SetClassificationAttribute da = setClassificationArr[0] as SetClassificationAttribute;
                  m.Classification = da.Type;
            }
            //Display
            object[] disArr = e.GetType().GetField(e.ToString()).GetCustomAttributes(typeof(DisplayAttributes), true);
            if (disArr != null && disArr.Length > 0)
            {
                  DisplayAttribute da = disArr[0] as DisplayAttribute;
                  m.Name = da.Name;
            }

            m.Value = Convert.ToInt32(e);
            m.Key = e.ToString();
            list.Add(m);
         }
         return list;
      }

static void Main(string[] args)
{

         // 获取枚举类型转为List，使用List的Where过滤条件
         var query =  _enumAppservice.EnumToList<ResourceState>().Where(e => e.Classification>=1&&e.Classification<=6).OrderBy(e=>e.Classification).ToList();
         Console.ReadKey();
      }
