在自定义JsonConverter中使用来自json的另一个属性

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using System;

public class CustomConverter : JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        // 判断待转换的类型是否为需要进行自定义转换的类型
        return objectType == typeof(MyObject);
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        JObject jsonObject = JObject.Load(reader);

        // 获取Json中的属性值
        string value = (string)jsonObject["anotherProperty"];

        // 根据需要进行转换操作
        // ...

        return new MyObject();
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        MyObject myObject = (MyObject)value;

        // 根据需要将对象转换为Json字符串
        // ...

        writer.WriteStartObject();
        writer.WritePropertyName("anotherProperty");
        writer.WriteValue("value");
        writer.WriteEndObject();
    }
}

public class MyObject
{
    public string Property1 { get; set; }
    public string Property2 { get; set; }
}

public class Program
{
    public static void Main(string[] args)
    {
        MyObject myObject = new MyObject { Property1 = "value1", Property2 = "value2" };

        string json = JsonConvert.SerializeObject(myObject, new CustomConverter());
        Console.WriteLine(json);

        MyObject deserializedObject = JsonConvert.DeserializeObject<MyObject>(json, new CustomConverter());
        Console.WriteLine(deserializedObject.Property1);
        Console.WriteLine(deserializedObject.Property2);
    }
