Question

If I have a class, Foo, looking like this…

class Foo
{
    public string TelephoneNumber1;
    public string TelephoneNumber2;
    public string TelephoneNumber3;
    public string TelephoneNumber4;
}

is it possible to use AutoMapper to map to this class…

class Bar
{
    public ContactInfo[] Contacts;
}

where ContactInfo is…

class ContactInfo
{
    public string TelephoneNumber;
}

if so, how?

Answer 1

Not exactly. You could map a Foo with a string[] of telephone numbers:

public class Foo
{
    public string[] TelephoneNumbers { get; set; }
}

Mapper.CreateMap<Foo, Bar>()
    .ForMember(dest => dest.Contacts, opt => opt.MapFrom(src => src.TelephoneNumbers));

Mapper.CreateMap<string, ContactInfo>()
    .ConvertUsing(value => new ContactInfo { TelephoneNumber = value });

Then you could map like so:

Bar bar = Mapper.Map<Foo, Bar>(foo);
