C＃automapper嵌套集合 [英] C# automapper nested collections

问题描述

我有一个简单的模型，像这样的：

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; }
   ... ...
}

我做些什么Automapper是这样的：

What I do with Automapper is this:

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

扔，说异常：在OrderDto财产OrderLineDtos没有映射
添加自定义的映射......
当我们使用自定义的语法在我们的领域，并在我们的DomainDto，我怎么可以指定在OrderDto收集OrderLineDtos对应至订单在订单？

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?

感谢您

推荐答案

它的工作原理是这样的：

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();
