AutoMapper map complex object

Question

I've been trying to use AutoMapper, but I'am having trouble configuring the map.

Having this:

public class A
{
    public B b { get; set; }
    public C c { get; set; }
    public int id { get; set; }
    public string X { get; set; }
}

public class B
{
    public int id { get; set; }
    public string Y { get; set; }
}

public class C
{
    public int id { get; set; }
    public string Z { get; set; }
}

public class ABC
{
    public int Aid { get; set; }
    public string AX { get; set; }
    public int Bid { get; set; }
    public string BY { get; set; }
    public int Cid { get; set; }
    public string CZ { get; set; }
}

How can I do mapping A > ABC and ABC > A.

I don't want to map each property manually. Is it possible?

Thank you.

Normally automapper expects property names to be same. For different names you need to configure mapping. So in your case you have to map each property in automapper. — Mukesh Modhvadiya

I am not sure what you mean by "I don't want to map each property manually". But with AutoMapper you could easily map the properties:

        Mapper.Initialize(cfg => cfg.CreateMap<A, ABC>()
            .ForMember(dest => dest.AX, opt => opt.MapFrom(src => src.X))
            .ForMember(dest => dest.Aid, opt => opt.MapFrom(src => src.id))
            .ForMember(dest => dest.BY, opt => opt.MapFrom(src => src.b.Y))
            .ForMember(dest => dest.Bid, opt => opt.MapFrom(src => src.b.id))
            .ForMember(dest => dest.CZ, opt => opt.MapFrom(src => src.c.Z))
            .ForMember(dest => dest.Cid, opt => opt.MapFrom(src => src.c.id)));

        var a = new A
        {
            X = "I am A",
            id = 0,
            b = new B()
            {
                Y = "I am B",
                id = 1
            },
            c = new C()
            {
                Z = "I am C",
                id = 2
            }
        };

        var abc = Mapper.Map<A, ABC>(a);
