序列化时避免展开链接对象

本文关键字：链接 对象 序列化 | 更新日期: 2023-09-27 17:56:29

我正在使用 JSON.NET 将一些c#对象序列化为JSON（然后写入文件）。

我的两个主要课程是：

public class Reservoir {
    private Well[] mWells;
    public Well[] wells {
        get { return mWells; }
        set { mWells = value; }
    }
}

和

public Well() {
    private string mWellName;
    private double mY;
    private double mX;
    public string wellName {
        get { return mWellName; }
        set { mWellName = value; }
    }

    public double y {
        get { return mY; }
        set { mY = value; }
    }
    public double x {
        get { return mX; }
        set { mX = value; }
    }
    private Well[] mWellCorrelations;
}

问题是输出如下所示：

'{"wells":[{"wellName":"B-B10","y":217.04646503367468,"x":469.5776343820333,"wellCorrelations":[{"wellName":"B-B12","y":152.71005958395972,"x":459.02158140110026,"wellCorrelations":[{"wellName":"B-B13","y":475.0,"x":495.14804408905263,"wellCorrelations":[{"wellName":"B-B11","y":25.0,"x":50.0,"wellCorrelations":[]}

即每个井对象的相关孔被扩展为对象本身，当存在许多关联对象时，这成为严重的空间和时间问题。

我想我更喜欢这样的东西：

'{"wells":[{"wellName":"B-B10","y":217.04646503367468,"x":469.5776343820333,"wellCorrelations":[{"wellName":"B-B12"}], {"wellName":"B-B11","y":217.04646503367468,"x":469.5776343820333,"wellCorrelations":[{"wellName":"B-B13"}

即仅维护井名称作为链接（假设其唯一性）。

有没有办法用 JSON.NET 做到这一点？

您已设置

serializer.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;

但这没有任何区别。

序列化时避免展开链接对象

您可以添加一个名为 WellCorrelations 的新只读属性，该属性仅获取井相关性的名称，并在 mWellCorrelations 上打上一个 JsonIngore 属性，如下所示：

[JsonIgnore]
private Well[] mWellCorrelations;
public string[] WellCorrelations 
{ 
    get { return mWellCorrelations.Select(w => w.wellName).ToArray(); }
}

这样，序列化程序将仅序列化相关井的名称。
