JsonException: Max allowed object depth reached while trying to export from type System.Single

在进行类转json字符串时，报错JsonException: Max allowed object depth reached while trying to export from type System.Single。

ok，实际上是类的属性中有json不能识别的数据类型.

JsonData

        public JsonData(bool boolean);
        public JsonData(double number);
        public JsonData(int number);
        public JsonData(long number);
        public JsonData(object obj);
        public JsonData(string str);

所以去除掉float吧！
