C＃automapper嵌套集合

本文介绍了C＃automapper嵌套集合的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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();
