这篇文章主要介绍了NewtonSoft.JSon解析天气数据时出错的解决方法,需要的朋友可以参考下

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":"\u6570\u636e\u83b7\u53d6\u6210\u529f","data":[[{"date":"2014-01-01","dis_id":"1119","dis_name":"\u5f90\u5dde\u5e02","url":"http:\/\/www.tianqiyubao.com\/local.php?dis_id=1119","weather":"1","wind":"\u897f\u98ce3-4\u7ea7","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":"\u5f90\u5dde\u5e02","url":"http:\/\/www.tianqiyubao.com\/local.php?dis_id=1119","weather":"1","wind":"\u897f\u98ce3-4\u7ea7","weather_name":"\u6674","weather_pic":"styles\/images\/icon2\/day\/1.png","humidity":"","tem":"13"},{"date":"2014-01-01","dis_id":"1119","dis_name":"\u5f90\u5dde\u5e02","url":"http:\/\/www.tianqiyubao.com\/local.php?dis_id=1119","weather":"1","wind":"\u5317\u98ce3-4\u7ea7","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。
