自引用循环导致映射堆栈溢出

根据文档,应尽可能为AutoMapper自动设置参考。

从6.1.0开始,preserverences在配置时自动设置

我还尝试将MaxDepth设置为1,但在以下映射中仍然出现堆栈溢出异常。我能以某种方式绕过这个问题吗?或者我需要修改视图模型吗?

cfg.CreateMap<ArticleViewModel, Article>(MemberList.Source)
    .MaxDepth(1)
    .EqualityComparison((src, dst) => src.Id == dst.Id);

导致堆栈溢出异常的代码:

var article = await iArticleRepository.GetAsync(id);
//The mapping below causes the exception
var mappedArticle = Mapper.Map<ArticleViewModel>(article);

实体:

public class Article: IEntity<int>
{
    [Key]
    public int Id { get; set; }

    ...

    public int SupplierId { get; set; }

    public virtual Supplier Supplier { get; set; }
}

public class Supplier: IEntity<int>
{
    [Key]
    public int Id { get; set; }

    ...

    public virtual ICollection<Contact> Contacts { get; set; }
}

public class Contact: IEntity<int>
{
    [Key]
    public int Id { get; set; }

    ...
    public virtual ICollection<Supplier> Suppliers { get; set; }
}

public class ArticleViewModel
{
    public int Id { get; set; }

    ...
    public SupplierViewModel Supplier { get; set; }

}

public class SupplierViewModel
{
    public int Id { get; set; }

    ...
    public List<ContactViewModel> Contacts { get; set; }

}

public class ContactViewModel
{
    public int Id { get; set; }
    ... 
    public List<SupplierViewModel> Suppliers { get; set; }
}
