需要安装如下包
AutoMapper public void ConfigureServices(IServiceCollection services) { #region 自动映射拥有MapAttribute的类 services.AddAutoMapper(); #endregion } /// <summary> /// 使用AutoMapper自动映射拥有MapAttribute的类 /// </summary> /// <param name="services">服务集合</param> /// <param name="configure">自定义配置</param> public static IServiceCollection AddAutoMapper(this IServiceCollection services, Action<IMapperConfigurationExpression> configure = null) { List<(Type from, Type[] targets)> maps = new List<(Type from, Type[] targets)>(); maps.AddRange(GlobalData.AllFxTypes.Where(x => x.GetCustomAttribute<MapAttribute>() != null) .Select(x => (x, x.GetCustomAttribute<MapAttribute>().TargetTypes))); var configuration = new MapperConfiguration(cfg => { maps.ForEach(aMap => { aMap.targets.ToList().ForEach(aTarget => { cfg.CreateMap(aMap.from, aTarget).IgnoreAllNonExisting(aMap.from, aTarget).ReverseMap(); }); }); cfg.AddMaps(GlobalData.AllFxAssemblies); //自定义映射 configure?.Invoke(cfg); }); #if DEBUG //只在Debug时检查配置 configuration.AssertConfigurationIsValid(); #endif services.AddSingleton(configuration.CreateMapper()); return services; } [Map(typeof(Base_User))] public class Base_UserDTO : Base_User { public string RoleNames { get => string.Join(",", RoleNameList ?? new List<string>()); } public List<string> RoleIdList { get; set; } public List<string> RoleNameList { get; set; } public RoleTypes RoleType { get { int type = 0; var values = typeof(RoleTypes).GetEnumValues(); foreach (var aValue in values) { if (RoleNames.Contains(aValue.ToString())) type += (int)aValue; } return (RoleTypes)type; } } public string DepartmentName { get; set; } public string SexText { get => Sex.GetDescription(); } public string BirthdayText { get => Birthday?.ToString("yyyy-MM-dd"); } } /// <summary> /// 系统用户表 /// </summary> [Table("Base_User")] public class Base_User { /// <summary> /// 主键 /// </summary> [Key, Column(Order = 1)] public String Id { get; set; } /// <summary> /// 创建时间 /// </summary> public DateTime CreateTime { get; set; } /// <summary> /// 创建人Id /// </summary> public String CreatorId { get; set; } /// <summary> /// 否已删除 /// </summary> public Boolean Deleted { get; set; } /// <summary> /// 用户名 /// </summary> public String UserName { get; set; } /// <summary> /// 密码 /// </summary> public String Password { get; set; } /// <summary> /// 姓名 /// </summary> public String RealName { get; set; } /// <summary> /// 性别 /// </summary> public Sex Sex { get; set; } /// <summary> /// 出生日期 /// </summary> public DateTime?
