如何在System.Text.Json.JsonSerializer中使用类字段? [英] How to use class fields with System.Text.Json.JsonSerializer?

问题描述

我最近将解决方案升级为全部.NET Core 3，并且我有一个类，要求类变量为字段.这是一个问题，因为新的System.Text.Json.JsonSerializer不支持序列化或反序列化字段，而仅处理属性.

I recently upgraded a solution to be all .NET Core 3 and I have a class that requires the class variables to be fields. This is a problem since the new System.Text.Json.JsonSerializer doesn't support serializing nor deserializing fields but only handles properties instead.

有什么方法可以确保以下示例中的两个最终类具有相同的确切值?

Is there any way to ensure that the two final classes in the example below have the same exact values?

using System.Text.Json;

public class Car
{
    public int Year { get; set; } // does serialize correctly
    public string Model; // doesn't serialize correctly
}

static void Problem() {
    Car car = new Car()
    {
        Model = "Fit",
        Year = 2008,
    };
    string json = JsonSerializer.Serialize(car); // {"Year":2008}
    Car carDeserialized = JsonSerializer.Deserialize<Car>(json);

    Console.WriteLine(carDeserialized.Model); // null!
}

推荐答案

当前，字段不可序列化.但是正在进行开发工作.您可以关注此线程.

Currently, fields are not serializable. But there is a development work in progress. You can follow this thread.
