Question

从ProjectTo doesn't support BeforeMap开始，如何将parent对象传递给children集合？这是代码：

void Main()
{
    Mapper.Initialize(c =>
    {
        c.AddProfile<Prof>();
    });

    myDbContext.Profiles
        .ProjectTo<ProfileDto>()
        .Dump(); // Linqpad Extension

}

public class Prof : Profile
{
    public Prof()
    {
        CreateMap<ProfileEntity, ProfileDto>();
        CreateMap<UserEntity, UserDto>();
    }
}

public class ProfileDto
{
    public string Name { get; set; }
    public IEnumerable<UserDto> Users { get; set; }
}

public class UserDto
{
    public string Name { get; set; }
    public string ProfileName { get; set; }
}

我只想填写“ProfileName”属性。

像这样使用AutoMapperConfiguration：

cfg.CreateMap<Prof, ProfileDto>()
                .ForMember(d => d.Users, opt => opt.MapFrom(src => src.Users.Select(x=>new UserDto { Name=x.Name,ProfileName=src.Name})));

Automapper ProjectTo从子级访问父级
