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

I saw the example of conditionally mapping, but it maps the field it performs the conditional check on. I want to check the condition and map a different field.

Try using such config:

cfg.CreateMap()
    .ForMember(dest => PersonMember.PersonMemberId, opt => { 
        opt.Condition(src => src.MemberType == "Person");
        opt.MapFrom(src => src.MemberId);
     });
cfg.CreateMap()
    .ForMember(dest => CompanyMember.CompanyMemberId, opt => { 
        opt.Condition(src => src.MemberType == "Company");
        opt.MapFrom(src => src.MemberId);
     });

In case you mapping from a non-compatible object Id field will be set to 0.
