如何将具有索引的数组映射到具有自定义JsonConverter的对象

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

public class CustomConverter : JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        return objectType == typeof(CustomObject);
    }

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

        // 获取索引数组
        JArray indexArray = (JArray)jsonObject["IndexArray"];

        // 创建自定义对象
        CustomObject customObject = new CustomObject();

        // 将索引数组映射到对象的属性
        for (int i = 0; i < indexArray.Count; i++)
        {
            customObject.Properties.Add(i, (string)indexArray[i]);
        }

        return customObject;
    }

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

        writer.WriteStartObject();

        // 将对象的属性写入JSON数据
        foreach (var property in customObject.Properties)
        {
            writer.WritePropertyName(property.Key.ToString());
            writer.WriteValue(property.Value);
        }

        writer.WriteEndObject();
    }
}

public class CustomObject
{
    [JsonConverter(typeof(CustomConverter))]
    public Dictionary<int, string> Properties { get; set; } = new Dictionary<int, string>();
}

public class Program
{
    public static void Main(string[] args)
    {
        // 创建具有索引的数组
        string json = @"{
            ""IndexArray"": [""Value1"", ""Value2"", ""Value3""]
        }";

        // 反序列化JSON数据到对象
        CustomObject customObject = JsonConvert.DeserializeObject<CustomObject>(json);

        // 输出对象的属性
        foreach (var property in customObject.Properties)
        {
            Console.WriteLine($"Index: {property.Key}, Value: {property.Value}");
        }

        // 序列化对象到JSON数据
        string serializedJson = JsonConvert.SerializeObject(customObject);
        Console.WriteLine(serializedJson);
    }
}

Index: 0, Value: Value1
Index: 1, Value: Value2
Index: 2, Value: Value3
{"0":"Value1","1":"Value2","2":"Value3"}
