C# automapper nested collections

Question

I have a simple model like this one:

public class Order{    public int Id { get; set; }    ... ...    public IList<OrderLine> OrderLines { get; set; } }  public class OrderLine{    public int Id { get; set; }    public Order ParentOrder { get; set; }    ... ... } 

What I do with Automapper is this:

    Mapper.CreateMap<Order, OrderDto>();     Mapper.CreateMap<OrderLine, OrderLineDto>();     Mapper.AssertConfigurationIsValid(); 

It throw an exception that says: "The property OrderLineDtos in OrderDto is not mapped, add custom mapping ..." As we use a custom syntax in our Domain and in our DomainDto, how I can specify that the collection OrderLineDtos in OrderDto corresponds to OrderLines in Order?

Thank you

It works in this way:

    Mapper.CreateMap<Order, OrderDto>()         .ForMember(dest => dest.OrderLineDtos, opt => opt.MapFrom(src => src.OrderLines));     Mapper.CreateMap<OrderLine, OrderLineDto>()         .ForMember(dest => dest.ParentOrderDto, opt => opt.MapFrom(src => src.ParentOrder));     Mapper.AssertConfigurationIsValid();
