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

Consider the following source classes:

class X {
    public string A { get; set; }
    public Y[] B { get; set; }
}

class Y {
    public string C { get; set; }
    public Z[] D { get; set; }
}

class Z {
    public string E { get; set; }
    public string F { get; set; }
}

And the following destination:

class Destination {
    public string A { get; set; }
    public string C { get; set; }
    public string E { get; set; }
    public string F { get; set; }
}

What I'd like to be able to do is get a List from one or more X, e.g.:

Mapper.Map<IEnumerable<X>, IEnumerable<Destination>>(arrayOfX);

I'm unable to figure out what sort of mapping configuration to use to achieve this. MapFrom seems like the way to go for 1:1 compositions, but doesn't seem to be able to handle the array (or other enumerable) unless I use AutoMapper's destination naming convention.

Any insights on how to achieve this?
