AutoMapper and flattening nested arrays

Question

I\'m trying to use AutoMapper to flatten multiple levels of arrays.

Consider the following source classes:

class X {
    public string A { get; set;         


        

Answer 1

Try this mapper,

Mapper.CreateMap();
Mapper.CreateMap();
Mapper.CreateMap()
    .ForMember(destination => destination.A, options => options.MapFrom(source => source.A)).IgnoreAllNonExisting()
    .ForMember(destination => destination.C, options => options.MapFrom(source => Mapper.Map, IEnumerable>(source.B).FirstOrDefault().C))
    .ForMember(destination => destination.E, options => options.MapFrom(source => Mapper.Map, IEnumerable>(source.B.SelectMany(d => d.D)).FirstOrDefault().E))
    .ForMember(destination => destination.F, options => options.MapFrom(source => Mapper.Map, IEnumerable>(source.B.SelectMany(d => d.D)).FirstOrDefault().F));

var result = Mapper.Map, IEnumerable>(arrayOfX);
