C# JSON 将值 3072 转换为类型 'WeatherUnderground.RootObject' 时出错

Question

我试图从这里反序列化json:

https://www.wunderground.com/weather/api/d/docs?MR=1

我是这样反序列化的:

RootObject oData = JsonConvert.DeserializeObject<RootObject>(jsonResponse.ContentString);

我已经使用http://jsonutils.com/来创建我的c#类。

    public class Features
{
    public int hourly10day { get; set; }

public class Response

}

}
public class RootObject
{
    public Response response { get; set; }
    public IList<HourlyForecast> hourly_forecast { get; set; }
}

但我仍然得到:

将值3072转换为类型"WeatherUnderground.RootObject"时出错。-在newtonsoft . json . serializable . jsonserializerinternalreader。EnsureType(对象值，类型targetType)

我做错了什么?此外，如果这与。net 3.5有任何关系，我正在使用。

谢谢

你的json和Class结构将是这样的。

这样做会给我适当的结果。

RootObject oData = JsonConvert.DeserializeObject<RootObject>(jsonResponse.ContentString);
