在使用DTO概念后,使用AutoMapper进行对象的映射,使用4.0.4版本的AutoMapper.
AutoMapper的辅助类：
/// <summary> /// AutoMapper扩展方法 /// </summary> public static class AutoMapperExtension { /// <summary> /// 类型映射 /// </summary> public static T MapTo<T>(this object obj) { if (obj == null) return default(T); Mapper.CreateMap(obj.GetType(), typeof(T)); return Mapper.Map<T>(obj); } /// <summary> /// 集合列表类型映射 /// </summary> public static List<TDestination> MapToList<TDestination>(this IEnumerable source) { foreach (var first in source) { var type = first.GetType(); Mapper.CreateMap(type, typeof(TDestination)); break; } return Mapper.Map<List<TDestination>>(source); } /// <summary> /// 集合列表类型映射 /// </summary> public static List<TDestination> MapToList<TSource, TDestination>(this IEnumerable<TSource> source) { //IEnumerable<T> 类型需要创建元素的映射 Mapper.CreateMap<TSource, TDestination>(); return Mapper.Map<List<TDestination>>(source); } }
有特殊字段需要进行处理的,可以使用ForMember
#region Mapper映射 Mapper.CreateMap<WareHouse_Achievement, AchievementOutputDto>().ForMember(c => c.TargetCompleteness, opt => { opt.MapFrom(s => s.AchievementTarget > 0 ? Math.Round((s.TotalAchiToday / s.AchievementTarget * 100), 2).ToString() + "%" : ""); }).ForMember(c => c.PointCompleteness, opt => { opt.MapFrom(s => s.BreakEvenPoint > 0 ? Math.Round((s.TotalAchiToday / s.BreakEvenPoint * 100), 2).ToString() + "%" : ""); }); var outs = Mapper.Map<List<AchievementOutputDto>>(list); var outList = AutoMapperExtension.MapToList<AchievementOutputDto>(list);
