今天用NewtonSoft.JSon解析一个天气数据，数据格式如：
复制代码 代码如下:
{"status":1,"detail":"u6570u636eu83b7u53d6u6210u529f","data":[[{"date":"2014-01-01","dis_id":"1119","dis_name":"u5f90u5ddeu5e02","url":"http://www.tianqiyubao.com/local.php?dis_id=1119","weather":"1","wind":"u897fu98ce3-4u7ea7","weather_name":"u6674","weather_pic":"styles/images/icon2/day/1.png","humidity":"","tem_min":"1","tem_max":"13","sunrise":"07:17","sunset":"17:12","pm":"109","air":"u826f","day_night":[{"date":"2014-01-01","dis_id":"1119","dis_name":"u5f90u5ddeu5e02","url":"http://www.tianqiyubao.com/local.php?dis_id=1119","weather":"1","wind":"u897fu98ce3-4u7ea7","weather_name":"u6674","weather_pic":"styles/images/icon2/day/1.png","humidity":"","tem":"13"},{"date":"2014-01-01","dis_id":"1119","dis_name":"u5f90u5ddeu5e02","url":"http://www.tianqiyubao.com/local.php?dis_id=1119","weather":"1","wind":"u5317u98ce3-4u7ea7","weather_name":"u6674","weather_pic":"styles/images/icon2/night/1.png","humidity":"","tem":"1"}]}]]}
结果就老报一个错误。
复制代码 代码如下:
Cannot deserialize JSON array (i.e. [1,2,3]) into type 'SweetWeather.MoreDayWeatherInfoFullDay'.
The deserialized type must be an array or implement a collection interface like IEnumerable, ICollection or IList.
To force JSON arrays to deserialize add the JsonArrayAttribute to the type. Path 'data[0]', line 1, position 69.
最后还是报错。仔细发现有两个方框号，原来是自己实体类的设计有问题，
原实体类：
复制代码 代码如下:
public string status { get; set; }
public string detail { get; set; }
public List<MoreDayWeatherInfoFullDay> data { get; set;
更正后的实体类：
复制代码 代码如下:
public string status { get; set; }
public string detail { get; set; }
public List<List<MoreDayWeatherInfoFullDay>> data { get; set; }
正确无误了。
