天气预报源代码
先上效果图
在这里更正一下，黑天的天气预报界面截图的时候，当时操作系统的时间是错误的，导致模拟器里显示2008年。
天气预报是我学WindowsPhone7以来的第一个作品。用的是谷歌的api。功能一个下午就写完了，还是这个界面的设计加P图费了我不少的时间。这个应用已经通过了微软的审核。

由于界面过于复杂，为了实现高效的重用性，我使用了用户自定义控件。通过后台对象的实例化生成的界面。没有办法把所有的代码都展现出来。
1: // 应用程序启动(例如，从“开始”菜单启动)时执行的代码
2: // 此代码在重新激活应用程序时不执行
3: private void Application_Launching(object sender, LaunchingEventArgs e)
4: {
5: if (!IsolatedStorageSettings.ApplicationSettings.Contains("City"))
6: {
7: List<CityWeatherInfo> citys = new List<CityWeatherInfo>();
8: IsolatedStorageSettings.ApplicationSettings["City"] = citys;
9: IsolatedStorageSettings.ApplicationSettings.Save();
10: }
11: }
1: List<CityWeatherInfo> citys = new List<CityWeatherInfo>();
我使用的是IsolatedStorageSettings.ApplicationSettings存储的城市信息。下面为添加城市信息的代码。
1: //添加城市
2: private void AddCityButton_Click(object sender, RoutedEventArgs e)
3: {
4:
5: if ((citys.Where(list => list.CityName == CityNameTextBox.Text).ToList()).Count == 0)
6: {
7: citys.Add(new CityWeatherInfo() { CityGuid = Guid.NewGuid().ToString(), CityName = CityNameTextBox.Text });
8: IsolatedStorageSettings.ApplicationSettings["City"] = citys;
9: IsolatedStorageSettings.ApplicationSettings.Save();
10: }
11: IsolatedStorageSettings.ApplicationSettings["City"] = citys;
12: IsolatedStorageSettings.ApplicationSettings.Save();
13: NavigationService.Navigate(new Uri("/Loading.xaml?cityName=" + CityNameTextBox.Text+"&AndGoPage=MainPage", UriKind.RelativeOrAbsolute));
14: }
1: //删除城市
2: private void linkButtonDel_Click(object sender, RoutedEventArgs e)
3: {
4: for (int i = 0; i < citys.Count; i++)
5: {
6: if (citys[i].CityGuid == ((HyperlinkButton)sender).Tag.ToString())
7: {
8: citys.RemoveAt(i);
9: }
10: }
11: IsolatedStorageSettings.ApplicationSettings["City"] = citys;
12: IsolatedStorageSettings.ApplicationSettings.Save();
13: BindData();
14: }
先上获取天气信息的代码，我自己写了个获取谷歌天气信息的工具类，生成了DLL然后引用进来使用的。
给城市赋天气信息
1: public partial class Loading : PhoneApplicationPage
2: {
3: List<CityWeatherInfo> citys = new List<CityWeatherInfo>();
4: WebClient client = new WebClient();
5: string cityName = "济南";
6: public Loading()
7: {
8: InitializeComponent();
9: citys = IsolatedStorageSettings.ApplicationSettings["City"] as List<CityWeatherInfo>;
10: }
11: private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
12: {
13: LoadingData();
14: }
15: string AndGoPage = "MainPage";
16: public void LoadingData()
17: {
18: AndGoPage = NavigationContext.QueryString["AndGoPage"];
19: if (NavigationContext.QueryString.ContainsKey("cityName"))
20: {
21: cityName = NavigationContext.QueryString["cityName"];
22: }
23: client.OpenReadAsync(new Uri("http://www.google.com/ig/api?hl=zh-cn&oe=utf8&weather=" + cityName, UriKind.RelativeOrAbsolute));
24: client.OpenReadCompleted += new OpenReadCompletedEventHandler(client_OpenReadCompleted);
25: }
26:
27: void client_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
28: {
29: XElement xmlWeather;
30: try
31: {
32: xmlWeather = XElement.Load(e.Result);
33: }
34: catch (Exception)
35: {
36: MessageBox.Show("获取城市信息失败");
37: NavigationService.Navigate(new Uri("/MainPage.xaml", UriKind.RelativeOrAbsolute));
38: return;
39: }
40: foreach (var item in citys)
41: {
42: if (item.CityName == cityName)
43: {
44: item.TodayIcon = GoogleWeatherHelper.GetTodayIcon(xmlWeather);
45: item.LastUpdateTime = DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss");
46: item.Humidity = GoogleWeatherHelper.GetHumidity(xmlWeather);
47: try
48: {
49: item.WindCondition = GoogleWeatherHelper.GetWindCondition(xmlWeather);
50: }
51: catch (Exception)
52: {

77: item.DaHouTianCondition = GoogleWeatherHelper.GetDaHouTianCondition(xmlWeather);
78: }
79: }
80: IsolatedStorageSettings.ApplicationSettings["City"] = citys;
81: IsolatedStorageSettings.ApplicationSettings.Save();
82: NavigationService.Navigate(new Uri("/" + AndGoPage + ".xaml?cityName=" + cityName, UriKind.RelativeOrAbsolute));
83: }
84: }
