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。

为什么更改键DEMO => demo却更改为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()
});
