我通过json将json运回c＃转换器。 我不打算包含所有生成的类，但是根对象返回一个DailyForecast列表。   您只需要进入根对象而不是根对象列表

I ran the json back through a json to c# converter.  I am not going to include all the classes generated but the root object returns an List of DailyForecast.   You only need to into a root object not a List of root objects

var result = JsonConvert.DeserializeObject<AccuWeather5DaysForecast.RootObject>(json_5days_forecast);
