Conditionally mapping one source type to two destination types

Question

I have a source DTO like this

public class Member 
{
    public string MemberId {get;set;}
    public string MemberType {get;set;}
    public string Name {g

With automapper you must specify return type on invocation mapper eg. mapper.Map(member), this tells that return type is PersonMember so you can't return CompanyMember.

You can do something like this:

var configPerson = new MapperConfiguration(cfg => cfg.CreateMap());
var configCompany = new MapperConfiguration(cfg => cfg.CreateMap());

PersonMember personMember = null;
CompanyMember companyMember = null;

switch (member.MemberType )
{
    case "PersonMember":
        var mapper = configPerson.CreateMapper();
        personMember = mapper.Map(member);
        break;
    case "CompanyMember":
        var mapper = configCompany.CreateMapper();
        companyMember = mapper.Map(member);
        break;
    default:
        throw new Exception("Unknown type");
        break;
}

Or you can try Custom type converters with object as return type.
