WP8页面跳转实现参数传递的多种方法

方法一:通过WEB传参方式进行传参
开始跳转页:
NavigationService.Navigate(new Uri("/Page/MainPage/XXXXPage.xaml?Address="+address,UriKind.RelativeOrAbsolute));
转入页:
//此方法应该在页面的Loaded方法体中实现
string address=NavigationContext.QueryString["address"];

方法二:通过独立存储方式进行传参
开始跳转页:
IsolatedStorageSettings iss = IsolatedStorageSettings.ApplicationSettings;
iss["ImageSource"] = image.source;
NavigationService.Navigate(new Uri(" /Page/MainPage/XXXXPage.xaml ", UriKind.Relative));
转入页:
IsolatedStorageSettings iss = IsolatedStorageSettings.ApplicationSettings;
image.Source = (BitmapImage)iss["ImageSource"];

方法三:通过 PhoneApplicationService来实现传参
开始跳转页:
PhoneApplicationService myService = PhoneApplicationService.Current;
protected override void OnNavigatedFrom(NavigationEventArgs e) {
      myService.State["address"] = " address ";
      base.OnNavigatedFrom(e);
}
转入页:
PhoneApplicationService myService = PhoneApplicationService.Current;
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e){
    object  address ;
    if (myService.State.ContainsKey(" address ")) {
        if (myService.State.TryGetValue(" address ", out  address )) {
            string address =  address .ToString();
        }
    }
    base.OnNavigatedTo(e);
}

方法四:通过App.xaml进行传参(共享参数)
App.xaml:
定义一个或几个用于传参的对象,如 public string Address{set;get;}
开始跳转页: 
(Application.Current as App). Address = "address";
转入页:
string address= (Application.Current as App). Address;
