public class SaveStaffFileDto ExtensibleObject summary 租户id summary public Guid TenantId get; set; summary 主键 summary public int Id

您可以使用CreateMap方法的ForMember方法来映射子类Basic_Job。具体的代码如下：

CreateMap<SaveStaffFileDto, StaffFile>() .ForMember(dest => dest.Job, opt => opt.MapFrom(src => new Basic_Job { Id = src.JobId })) .ForMember(dest => dest.Post, opt => opt.MapFrom(src => new Basic_Post { Id = src.PostId }));
