是否可以使用循环引用执行序列化？

Question

So, my entity class (written in C#) follows a parent child model where every child object must have a Parent property in which it keeps reference of its Parent.

This Parent property causes issues in serialization of the Object due to circular references.

I can't remove the reference to parent, neither I can mark it XmlIgnore (since I need to read it back when I deserialize the XML)

Any ideas on this?

Answer 1

XML serialization doesn't support circular references, you need to exclude the parent property from the serialization using the XmlIgnore attribute. See this blog post for a way to maintain the relationship when you deserialize.

Alternatively, you could use DataContractSerializer instead of XmlSerializer . It supports circular references, but doesn't provide much control over the XML schema...

Answer 2

您可以创建自己的XMLSerializer也可以使用DataContractSerializer和[DataContract( IsReference = true)]属性来告诉序列化程序记住引用。
