如何在反序列化时自动将.net核心接口FromBody参数中的数字转换为字符串？

public class NumberToStringConverter : JsonConverter<string>
{
    public override string Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options)
    {
        if (reader.TokenType == JsonTokenType.Number)
        {
            return reader.GetInt32().ToString();
        }

        return reader.GetString();
    }

    public override void Write(Utf8JsonWriter writer, string value, JsonSerializerOptions options)
    {
        writer.WriteStringValue(value);
    }
}

public class MyModel
{
    [JsonConverter(typeof(NumberToStringConverter))]
    public string MyProperty { get; set; }
}

[HttpPost]
public IActionResult MyAction([FromBody] MyModel model)
{
    // 使用转换后的字符串
    var value = model.MyProperty;
    
    // 其他处理逻辑
    
    return Ok();
}
