I know we can set the Context items when we call Map(), and it will be available to every map operation. Is there a way to change those context items during mapping?
Suppose I have these source types:
public class OuterSource {
public string TimeZone { get; set; }
public string Name { get; set; }
public InnerSource[] InnerArray { get; set; }
}
public class InnerSource {
public DateTime Created { get; set; }
public string Message { get; set; }
}
and these destination types:
public class OuterDest {
public string Name { get; set; }
public InnerDest[] InnerArray { get; set; }
}
public class InnerDest {
public DateTime Created { get; set; }
public string Message { get; set; }
}
The only difference is that InnerSource.Created is in UTC and I want to map it to the local time zone. However the time zone is in OuterSource, not InnerSource.
Normally, I would set up my mappers like so:
CreateMap<OuterSource, OuterDest>();
CreateMap<InnerSource, InnerDest>();
But that wouldn't work because when it comes to mapping InnerSource to InnerDest it does not have access to OuterSource.TimeZone.
So I'm currently forced to set my mapping like so:
CreateMap<OuterSource, OuterDest>()
.ForMember(dest => dest.InnerArray, opt => opt.ResolveUsing(
//loop through source.InnerArray and do the datetime
//conversion manually
));
I consider that a code smell. What I would love to do is to pass the timezone to the nested mapping somehow. I would appreciate any pointers towards that direction.
