寻求可省略属性名的C#序列化/反序列化协议以压缩API响应

我想缩减大API调用的JSON响应体积，知道可以用MessagePack但不想处理它的一些缺点。我的大部分场景里，超过一半的数据都是重复出现的属性名，因此有以下需求：

• 找一种能省略属性名的序列化/反序列化协议
• 最好支持数据压缩
• 必须是C#实现
• 希望能在响应中提供上下文/Schema，让客户端解析更轻松灵活

我准备了一个示例，模拟返回100000辆汽车和约425000个车轮的API调用，灵感来自OpenAPI规范，看下面JSON里的data属性：

C#实体类 #

public class Car
{
    public int Year { get; set; }
    public string Model { get; set; }
    public List<Wheel> Wheels { get; set; }
}

public class Wheel
{
    public double Diameter { get; set;}
    public string TireSize { get; set; }
    public string BoltPattern { get; set; }
}

期望的响应结构 #

{
    "responseDataType": {// 这个属性固定存在，说明"data"属性的类型
        "type": "array",
        "items": {
            "$ref": "#/schemas/Car"
        }
    },
    "schemas": {// "data"属性的模板/类型定义
        "Car": {
            "type": "object",
            "properties": {
                "year": {
                    "type": "integer"
                },
                "model": {
                    "type": "string"
                },
                "wheels": {
                    "type": "array",
                    "items": {
                        "$ref": "#/schemas/Wheel"
                    }
                }
            }
        },
        "Wheel": {
            "type": "object",
            "properties": {
                "diameter": {
                    "type": "number"
                },
                "tireSize": {
                    "type": "string"
                },
                "boltPattern": {
                    "type": "string"
                }
            }
        }
    },
    "data":[
         {/* 99998条数据... */},
         // 可以看到属性名没有重复，反序列化器会根据提供的"schemas"/"responseDataType"解析
         // 还可以去掉缩进节省更多空间，甚至压缩？
        {
            2000,
            "Toyota",
            [
                {16,"275/40r16","4x100"},
                {16,"275/40r16","4x100"},

                {16,"275/40r16","4x100"}            
            ]
        },
        {
