C# AutoMapper Conditional Mapping based upon target value

Question

Please can any one advise how to use conditional mapping in AutoMapper to map a value in the TARGET object from a SOURCE object based upon an existing TARGET property value?

Answer 1

Try this:

Mapper.CreateMap()
.ForMember(
        destination => destination.Nickname,
        option => 
        {
            option.Condition(rc => 
            {
                var profileViewModel = (ProfileViewModel)rc.InstanceCache.First().Value;
                return profileViewModel.NicknameIsVisible;
            });

            option.MapFrom(source => source.Nickname);
        }
);
