将具有十六进制值的JSON反序列化为sbyte属性时，JsonConvert.DeserializeObject引发异常

using System;
using Newtonsoft.Json;

public class MyObject
{
    public sbyte MyProperty { get; set; }
}

public class Program
{
    public static void Main()
    {
        string json = "{\"MyProperty\": \"0x7F\"}";

        // 将十六进制值转换为十进制值
        string hexValue = json.Replace("0x", "");
        sbyte decimalValue = Convert.ToSByte(hexValue, 16);

        // 创建一个包含sbyte属性的对象
        MyObject obj = new MyObject { MyProperty = decimalValue };

        // 将JSON字符串反序列化为对象
        MyObject deserializedObj = JsonConvert.DeserializeObject<MyObject>(JsonConvert.SerializeObject(obj));

        Console.WriteLine(deserializedObj.MyProperty);
    }
}
