C#实现解析百度天气数据,Rss解析百度新闻以及根据IP获取所在城市的方法
本文实例讲述了C#实现解析百度天气数据,Rss解析百度新闻以及根据IP获取所在城市的方法，分享给大家供大家参考。具体实现方法如下：
一、百度天气
接口地址:http://api.map.baidu.com/telematics/v3/weather?location=上海&output=json&ak=hXWAgbsCC9UTkBO5V5Qg1WZ9，其中ak是密钥，自行去申请即可，便于大家测试，楼主就公布并了自己的Key，这样可以直接获取到数据。
获取到的数据是这样的：
{"error":0,"status":"success","date":"2014-10-27","results":[{"currentCity":"上海","pm25":"95","index":[{"title":"穿衣","zs":"较舒适","tipt":"穿衣指数","des":"建议着薄外套、开衫牛仔衫裤等服装。年老体弱者应适当添加衣物，宜着夹克衫、薄毛衣等。"},{"title":"洗车","zs":"较适宜","tipt":"洗车指数","des":"较适宜洗车，未来一天无雨，风力较小，擦洗一新的汽车至少能保持一天。"},{"title":"旅游","zs":"适宜","tipt":"旅游指数","des":"天气较好，温度适宜，但风稍微有点大。这样的天气适宜旅游，您可以尽情地享受大自然的无限风光。"},{"title":"感冒","zs":"较易发","tipt":"感冒指数","des":"天气较凉，较易发生感冒，请适当增加衣服。体质较弱的朋友尤其应该注意防护。"},{"title":"运动","zs":"较适宜","tipt":"运动指数","des":"天气较好，但风力较大，推荐您进行室内运动，若在户外运动请注意防风。"},{"title":"紫外线强度","zs":"弱","tipt":"紫外线强度指数","des":"紫外线强度较弱，建议出门前涂擦SPF在12-15之间、PA+的防晒护肤品。"}],"weather_data":[{"date":"周一10月27日(实时：19℃)","dayPictureUrl":"http://api.map.baidu.com/images/weather/day/duoyun.png","nightPictureUrl":"http://api.map.baidu.com/images/weather/night/duoyun.png","weather":"多云","wind":"东北风3-4级","temperature":"21~16℃"},{"date":"周二","dayPictureUrl":"http://api.map.baidu.com/images/weather/day/duoyun.png","nightPictureUrl":"http://api.map.baidu.com/images/weather/night/yin.png","weather":"多云转阴","wind":"东风微风","temperature":"21~17℃"},{"date":"周三","dayPictureUrl":"http://api.map.baidu.com/images/weather/day/xiaoyu.png","nightPictureUrl":"http://api.map.baidu.com/images/weather/night/xiaoyu.png","weather":"小雨","wind":"东风微风","temperature":"21~19℃"},{"date":"周四","dayPictureUrl":"http://api.map.baidu.com/images/weather/day/xiaoyu.png","nightPictureUrl":"http://api.map.baidu.com/images/weather/night/xiaoyu.png","weather":"小雨","wind":"东南风微风","temperature":"23~20℃"}]}]}
根据返回的Json定义出相应的数据结构:
publicclassBaiduTQ
{
publicinterror{get;set;}
publicstringstatus{get;set;}
publicstringdate{get;set;}
publicList<BaiduResult>results{get;set;}
}
publicclassBaiduResult { publicstringcurrentCity{get;set;} publicstringpm25{get;set;} publicList<BaiduIndex>index{get;set;} publicList<BaiDuWeaterData>weather_data{get;set;} }
publicclassBaiduIndex { publicstringtitle{get;set;} publicstringzs{get;set;} publicstringtipt{get;set;} publicstringdes{get;set;} }
publicclassBaiDuWeaterData { publicstringdate{get;set;} publicstringdayPictureUrl{get;set;} publicstringnightPictureUrl{get;set;} publicstringweather{get;set;} publicstringwind{get;set;} publicstringtemperature{get;set;} }
