如何阻止JsonConvert.SerializeObject在将XML转换为JSON时将int转换为字符串

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

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

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        writer.WriteValue(value.ToString());
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        JToken token = JToken.Load(reader);
        if (token.Type == JTokenType.Integer)
        {
            return token.ToObject<int>();
        }
        throw new JsonSerializationException("Unexpected token type: " + token.Type);
    }
}

using Newtonsoft.Json;

// 创建一个JsonSerializerSettings对象
JsonSerializerSettings settings = new JsonSerializerSettings();
// 将自定义转换器添加到Converters集合中
settings.Converters.Add(new IntConverter());

// 将XML转换为JSON
string json = JsonConvert.SerializeObject(xmlObject, settings);
