json.net；序列化实体框架对象(循环引用错误)

问题描述

我有一个实体框架实体，我想将其序列化为 json 对象.我环顾四周，发现 json.net (http://james.newtonking.com/projects/json-net.aspx) 应该能够使用开箱即用"的循环引用序列化对象.所以我尝试使用

I have an entity framework entity that i want to serialize as a json object. I looked around and found out that json.net (http://james.newtonking.com/projects/json-net.aspx) should be able to serialize objects with circular references "out of the box". So i tried using

string json = JsonConvert.SerializeObject(/* my ef entity */);

但我仍然遇到同样的错误.问题可能是我需要使用 ReferenceLoopHandling.Ignore 和 ContractResolver，但我不确定如何使用它们.任何帮助深表感谢！谢谢

But im still getting the same error. The problem might be that i need to use ReferenceLoopHandling.Ignore and a ContractResolver, but im not sure how to use them. Any help is much appreciated! Thanks

推荐答案

我的解决方案是简单地删除子实体上的父引用.

My solution was to simply remove the parent reference on my child entities.

所以在我的模型中，我选择了关系并将父引用更改为内部而不是公共.

So in my model, I selected the relationship and changed the Parent reference to be Internal rather than Public.

可能不是所有人的理想解决方案，但对我有用.

May not be an ideal solution for all, but worked for me.
