[英]AutoMapper MaxDepth() method
In my project I have a one to many relationship from Client -> Projects
. 在我的项目中,我与
Client -> Projects
有一对多的关系。 As such, in one of my views, I am trying to show all of the Projects that belong to that Client. 因此,在我的一个视图中,我试图显示属于该客户端的所有项目。 So I have an
IEnumerable<ProjectDetailsViewModel>
that represents all of the clients projects. 所以我有一个代表所有客户端项目的
IEnumerable<ProjectDetailsViewModel>
。
The problem is that the ProjectDetailsViewModel
has a ClientDetailsViewModel
which then has an IEnumerable<ProjectDetailsViewModel>
and so on and so forth creating an endless loop of identical entities. 问题是
ProjectDetailsViewModel
有一个ClientDetailsViewModel
,然后有一个IEnumerable<ProjectDetailsViewModel>
等等,创建了一个无限循环的相同实体。
Is this where it is appropriate to use the MaxDepth() method on that .ForMember()? 这是否适合在.ForMember()上使用MaxDepth()方法? If so, how do I use it in this case, and if not, what is the solution?
如果是这样,我在这种情况下如何使用它,如果没有,解决方案是什么?
I have tried MaxDepth(1) on the Client
and whilst this prevents the StackOverflow exception, it then doesn't hold any data in the view model for that client. 我在
Client
上尝试过MaxDepth(1),虽然这可以防止StackOverflow异常,但它不会在该客户端的视图模型中保存任何数据。
The problem was that I explicitly called AutoMapper from with the AutoMapConfig
as such: 问题是我使用
AutoMapConfig
显式调用了AutoMapper:
.ForMember(x => x.Client, opt => opt.MapFrom(src =>
AutoMapper.Mapper.Map<ClientDetailsViewModel>(src.Client)))
If I just define it as: 如果我只是将其定义为:
.ForMember(x => x.Client, opt => opt.MapFrom(src => src.Client))
AutoMapper will know to stop after 1 recursion, and as I already have a map from Client -> ClientDetailsViewModel
there is no problem. AutoMapper将知道在1次递归后停止,并且因为我已经有来自
Client -> ClientDetailsViewModel
的地图,所以没有问题。
