[英]Automapper incorrectly populating parent/child structure
I have the following entity classes, which are mapped from virtually identical view model classes:我有以下实体类,它们是从几乎相同的视图 model 类映射的:
public class Node
{
public IList<Node> Children { get; set; }
public Node Parent { get; set; }
public string Text { get; set; }
}
public class Tree
{
public Node Root { get; set; }
}
Using the following view model structure使用如下视图model结构
Tree
-> Root
-> Children { node1, node2 }
Once the view model is mapped to the entity, the first child node, of the root node, is the root node and, as a result, I'm getting an infinite loop when I traverse the entity object structure.一旦视图 model 映射到实体,根节点的第一个子节点就是根节点,因此,当我遍历实体 object 结构时,我得到一个无限循环。
Anybody have an idea why this is happening and how to resolve it?任何人都知道为什么会发生这种情况以及如何解决它?
Many thanks非常感谢

Mapper.CreateMap<NodeViewModel, Node>()
.ForMember(dto => dto.Children,
opt => opt.MapFrom(src => src.Children.Select(nodevm => Mapper.Map<NodeViewModel, Node>(nodevm)).ToList()))
.ForMember(dto => dto.Parent,
opt => opt.MapFrom(src => Mapper.Map<NodeViewModel, Node>(src.Parent)))
.ForMember(dto => dto.Text,
opt => opt.MapFrom(src => src.Text));
Something like that schould work as the AutoMapper Configuration.类似的东西应该作为 AutoMapper 配置工作。
PS: I did not try it by now, but as I use the AutoMapper very often I think it should work. PS:我现在还没有尝试过,但由于我经常使用 AutoMapper,我认为它应该可以工作。
