newtonsoft.json的大小驼峰及蛇形命名法转换实现跨平台沟通

C#的属性是大驼峰命名法，python字段是蛇形命名法，C++是小驼峰命名法，C++和python无法反序列化C#序列化得到的Json字符串。
newtonsoft.json功能很强大，他能在序列化或反序列时，自动实现三种命名法的转换。

class MessageBody
{
    public int MyIDNum { get; set; }
    public bool IsCheck { get; set; }
}

序列化时，采用大驼峰，小驼峰，还是蛇形命名法随意选择

MessageBody msg = new MessageBody() { MyIDNum = 1, IsCheck = false };

string json = JsonConvert.SerializeObject(msg,Formatting.Indented);
Console.WriteLine(json);

json = JsonConvert.SerializeObject(msg,Formatting.Indented,new JsonSerializerSettings()
{
    ContractResolver = new CamelCasePropertyNamesContractResolver()
});
Console.WriteLine(json);

json = JsonConvert.SerializeObject(new MessageBody() { MyIDNum = 1, IsCheck = false }, Formatting.Indented, new JsonSerializerSettings()
{
    ContractResolver = new DefaultContractResolver() { NamingStrategy = new SnakeCaseNamingStrategy() }
});
Console.WriteLine(json);
//{
//  "MyIDNum": 1,
//  "IsCheck": false
//}
//{
//  "myIDNum": 1,
//  "isCheck": false
//}
//{
//  "my_id_num": 1,
//  "is_check": false
//}

反序列化时，可以把蛇形的Json字符串反序列成大驼峰命名法的.NET对象

MessageBody body = JsonConvert.DeserializeObject<MessageBody>("{‘my_id_num‘:1,‘is_check‘:false}", new JsonSerializerSettings() { ContractResolver = new DefaultContractResolver() { NamingStrategy = new SnakeCaseNamingStrategy() } });
Console.WriteLine(body.MyIDNum);
Console.WriteLine(body.IsCheck);
//1
//False
