如何序列为JSON循环引用的对象结构？ [英] How to serialize as Json an object structure with circular references?

问题描述

我有一个对象的结构是这样的：

I have an object structure like this:

public class Proposal {
    public List<ProposalLine> Lines { get; set; }
    public string Title { get; set; }
}

public class ProposalLine {
    public Proposal Proposal { get; set; }  // <- Reference to parent object
}

我尝试序列议案为JSON，它告诉我，有一个循环引用，这是正确的。结果
不幸的是，我不能碰的对象，因为它们是从其他项目中引用的DLL - 否则我会改变他们。

I try to serialize Proposal as Json, it tells me that there is a circular reference, which is correct.
Unfortunately, I can't touch the objects, since they are in a referenced DLL from another project - otherwise I'd change them.

有没有办法来序列为JSON而忽略循环特性？

Is there a way to serialize as Json and ignore the circular properties?

推荐答案

使用的Newtonsoft.Json（这是默认的.NET JSON序列化），并设置

Use the Newtonsoft.Json (which is the default .net json serializer) and set

JsonSerializerSettings settings = new JsonSerializerSettings
{
    PreserveReferencesHandling = PreserveReferencesHandling.Objects
};
var serializer = JsonSerializer.Create(settings);

如果您正在开发MVC应用也可以全局定义这个变量...

You can also globally define this variable if you are developing MVC applications...
