Mapster - 如何访问父对象

Question

使用 Mapster 时，我希望在映射子对象时能够访问父对象。我该怎么做？

class Parent {
 public int Id {get;set;}
 public Child Child {get;set;}
}

class Child {
 public int ParentId {get;set;}
 public string Name {get;set;}
}

...
config.NewConfig<Parent, ParentModel>()
 .Map(dest => dest.Id, src => src.Id)
 .Map(dest => dest.Child, src => src.Child);

config.NewConfig<Child, ChildModel>()
 .Map(dest => dest.Name, src => src.Name)
 .Map(dest => dest.ParentId, src => // How do I access the parent.Id);

Answer 1

您可以在父映射配置中映射子对象。

config.NewConfig<Parent, ParentModel>()
    .Map(dest => dest.Child.ParentId, src => src.Id);
