AutoMapping Array to a List

问题

class A
{
  public List<string> list;
}

class B
{
  public string[] array;
}

How would you map this?

I've tried

CreateMap<A,B>();

That doesn't work

回答1:

Your first issue is going to be that the class members don't match. If they did, I'd imagine that this would work. If not, you just have to specify your mapping rather than letting Automapper infer it:

CreateMap<A,B>()
    .ForMember(d => d.array, opts => opts.MapFrom(s => s.list.ToArray());

回答2:

For a shortcut, a vb.net version

CreateMap(Of A, B)().ForMember(Function(d) d.array, Sub(opts) opts.MapFrom(Function(s) s.list.ToArray()))
