使用Newtonsoft在驼峰式字典中使用字典密钥的Json序列化的奇怪行为

Question

我正在使用Newtonsoft CamelCasePropertyNamesContractResolver将对象序列化为json。 我看到字典键的奇怪的属性名称转换。

为什么要更改密钥DEMO => demo但DEMO Long => demO Long （大写O而不是小o）？

更多测试：

Dictionary Key        Json Property Name(After serialization)
------------          ----------------
THISISMYKEY           thisismykey
DEMO                  demo
DEMO Long             demO Long
LONGDEMOKAY           longdemokay
OOOO oOOOoo           oooO oOOOoo       

C＃参考代码：

Dictionary<string, long> collection = new Dictionary<string, long>();
collection.Add("THISISMYKEY", 100);
collection.Add("DEMO", 200);
collection.Add("thisissmallkey", 300);
collection.Add("LONGDEMOKAY", 400);
collection.Add("THISISOTHER", 500);
collection.Add("OOOO oOOOoo", 600);
collection.Add("DEMO Long", 700);

var response = JsonConvert.SerializeObject(collection, new JsonSerializerSettings{
  ContractResolver = new CamelCasePropertyNamesContractResolver()
});

您确定具有Newtonsoft.Json的最新版本和12.0.3版本吗，我的示例中与此结果相关：

{"thisismykey":100,"demo":200,"thisissmallkey":300,"longdemokay":400,"thisisother":500,"oooo oOOOoo":600,"demo Long":700}

我没看到任何问题吗？
