I can certainly test this. My question would then be, will this result in actually mapping a null in the dto, or would the .ExampleProperty? just "be null" and cause the long property to instantiate to 0?
One way to find out ;) not sure...
i'm pretty sure it'll be a
long?
- did you try it?So.. When I change...
.ForMember(ee => ee.ExampleId, options => options.MapFrom(ed => ed.ExampleProperty != null ? ed.ExampleProperty.ExampleId : (long?)null))
TO:
.ForMember(ee => ee.ExampleId, options => options.MapFrom(ed => ed.ExampleProperty?.ExampleId))
I am presented with: CS8072 - An expression tree lambda may not contain a null propagating operator.
there you go! thanks for updating, good to know
