I am using Automapper in my project to map business entities to DTO.
public class TransportStop
{
public Point[] Points { get; set; }
}
public class TransportStopDto
{
public PointDto[] Points { get; set; }
public TransportStopDto()
{
Points = new PointDto[0];
}
}
In constructor I am initializing Points property with an empty array to make sure it is always not null. I am using basic configuration for mapping.
Mapper.CreateMap<Point, PointDto>();
Mapper.CreateMap<TransportStop, TransportStopDto>();
TransportStop stop = new TransportStop()
{
Points = new Point[]
{
new Point() { X = 1, Y = 1 },
new Point() { X = 2, Y = 2 }
}
};
TransportStopDto dto = Mapper.Map<TransportStop, TransportStopDto>(stop);
With Automapper 2.0.0 it worked just fine, but after upgrading to version 2.2.0 I get mapping exception with inner exception:
Index was outside the bounds of the array
It seems Automapper tries to map every member of array, instead of overwriting the whole array. If I remove property initialization from constructor and leave it null, everything works.
Is it possible to configure Automapper 2.2.0 to always overwrite existing array property with new one?
