Asp .net core中使用AutoMapper数据映射

安装nuget包

注册服务

services.AddAutoMapper(AppDomain.CurrentDomain.GetAssemblies());

创建映射配置文件

配置类如下

public class TouristRouteProfile : Profile
    {
        public TouristRouteProfile()
        {
            CreateMap()
                .ForMember(
                    dest => dest.Price,
                    opt => opt.MapFrom(src => src.OriginalPrice * (decimal)    (src.DiscountPresent ?? 1)))
                .ForMember(
                    dest => dest.TravelDays,
                    opt => opt.MapFrom(src => src.TravelDays))
                .ForMember(
                    dest => dest.TripType,
                    opt => opt.MapFrom(src => src.TripType))
                .ForMember(
                    dest => dest.DepartureCity,
                    opt => opt.MapFrom(src => src.DepartureCity));

            CreateMap()
                .ForMember(
                    dest => dest.Id,
                    opt => opt.MapFrom(src => Guid.NewGuid()));

            CreateMap();

            CreateMap();
        }
    }

注入依赖

private readonly IMapper _mapper;
