Question

I found this solution AutoMapper – setting destination string to null actually makes it string.Empty

but It uses the Initialize method so all the mappings behavior would change along the app : O

And I just need do it for a specific mapping.

Answer 1

Found a solution:

Mapper.Initialize( Conf =>
  {
    Conf.ForSourceType<MyGreatViewModel>().AllowNullDestinationValues = true;
  } );

Thanks guys : )

Take care of your destination field types (remember you need nullable types. e.g. ‘Byte?’ )
