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View Code/// </summary> [Description("交易成功")] Success = 2, /// <summary> /// 廢標 /// </summary> [Description("廢標")] AbandonedTender = 6, /// <summary> /// 違約標 /// </summary> [Description("違約標")] DefaultMark= 7, /// <summary> /// 中標 /// </summary> [SetClassification(Type = 5)] [Description("中標")] WinTheBidding = 3, /// <summary> /// 流標 /// </summary> [SetClassification(Type = 6)] [Description("流標")] FlowStandard= 4, /// <summary> /// 未中標 /// </summary> [SetClassification(Type = 4)] [Description("未中標")] LoseABid = 5, /// <summary> /// 競價中 /// </summary> [SetClassification(Type = 2)] [Description("競價中")] Bidding = 8, /// <summary> /// 競拍中 /// </summary> [SetClassification(Type = 3)] [Description("競拍中")] Auctioning = 9, /// <summary> /// 已處理（針對於流標資源） /// </summary> [Description("已處理")] Alreadyprocessed = 10, /// <summary> /// 已過期 /// </summary> [Description("已過期")] ExpiredTime = 11, /// <summary> /// 所有報價 /// </summary> [SetClassification(Type = 1)] [Description("所有報價")] All = 12 } /// <summary> /// 添加自定義屬性 /// 作用：過濾枚舉類型 /// </summary> public class SetClassificationAttribute : Attribute { /// <summary> /// 分類 /// </summary> public int Type { get; set; } public SetClassificationAttribute() { } }
定義一個枚舉，想要顯示 classification type 從1 到 6的數據到一個list，list中對象有描述，值，type等屬性
public class EnumberCreditType { /// <summary> /// 枚舉的描述 /// </summary> public string Desction { set; get; } /// <summary> /// 枚舉名稱 /// </summary> public string Key { set; get; } /// <summary> /// 枚舉對象的值 /// </summary> public int Value { set; get; } /// <summary> /// 描述 /// </summary> public string Name { get; set; } /// <summary> /// 分類 /// </summary> public int Classification { set; get; } }View Code
代碼如下：
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(DisplayNameAttribute), true); if (disArr != null && disArr.Length > 0) { DisplayNameAttribute da = disArr[0] as DisplayNameAttribute; m.Name = da.DisplayName; } m.Value = Convert.ToInt32(e); m.Key = e.ToString(); list.Add(m); } return list; }View Code
var query = EnumToList<ResourceState>().Where(e => e.Classification >= 1 && e.Classification <= 6).OrderBy(e => e.Classification).ToList();
