通过使用自动映射器将嵌套的对象集合映射到另一个对象

Question

我在映射复杂的嵌套对象时遇到问题。将集合AddressDto对象映射（添加）到BookDto对象时，AutoMapper崩溃。

public class Mapper : IMapper
{
    public AutoMapper.IMapper Just { get; }

    public Mapper()
    {
        Just = new AutoMapper.MapperConfiguration(config =>
        {
            config.CreateMap<Address, AddressDto>();
            config.CreateMap<Book, BookDto>();
            config.CreateMap<Author, AuthorDto>();
            config.CreateMap<IEnumerable<AddressDto>, BookDto>()
                  .ForMember(bookDto => bookDto.Authors, authors => authors
                  .MapFrom(author => author));
                  .MapFrom(author => author));
        })
        .CreateMapper();

    public T1Destination Map<T1Source, T1Destination, T2Source, T2Destination>(T1Source t1Source, T2Source t2Source)
    {
        var destination1 = Just.Map<T1Source, T1Destination>(t1Source);
        var destination2 = Just.Map<T2Source, T2Destination>(t2Source);
        return Just.Map<T2Destination, T1Destination>(destination2, destination1);  // <-- Crash place
    }
}

程序使用以下方法调用Map方法：

from book in books
select _mapper.Map<Book, BookDto, IEnumerable<Author>, IEnumerable<AuthorDto>>(
    book,
    (from association in associations
    join author in authors
    on association.AuthorId equals author.Id
    where association.BookId == book.Id
    select author).ToList()
);

图书班：

public class Book
{
    // Some constructor

    public string Title { get; protected set; }
    public string Publisher { get; protected set; } // Kto opublikował (data)
    public string Language { get; protected set; }
    public int? Hardcover { get; protected set; } // Ilość stron
    public string Binder { get; protected set; }
    public decimal? Weight { get; protected set; }
    public string Dimensions { get; protected set; }
    public string ISBN { get; protected set; }
    public string Type { get; protected set; }
    public Guid Id { get; protected set; }
    public string Description { get; protected set; }
    public string Department { get; protected set; }
    public decimal Price { get; protected set; }
    public DateTime CreatedAt { get; protected set; }
    public DateTime UpdateAt { get; protected set; }
}

BookDto类：

public class BookDto
{
    public string Title { get; set; }
    public string Publisher { get; set; }
    public string Language { get; set; }
    public int? Hardcover { get; set; }
    public decimal? Weight { get; set; }
    public string Dimensions { get; set; }
    public string ISBN { get; set; }
    public string Type { get; set; }
    public decimal Price { get; set; }
    public IEnumerable<AuthorDto> Authors { get; set; }
}

作者类：

public class Author
{
    // Some constructor

    public Guid Id { get; protected set; }
    public string Name { get; protected set; }
    public string Surname { get; protected set; }
}

AuthorDto类：

public class AuthorDto
{
    public string Name { get; set; }
    public string Surname { get; set; }
    public IEnumerable<BookDto> ReleasedBooks { get; set; }
}

您能帮助我正确编写AutoMapper的配置还是找到更好的解决方案？
