WP8页面跳转实现参数传递的多种方法（已完善）

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"];

判断是否存在：
if (NavigationContext.QueryString.ContainsKey("address"))
{
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;

判断是否存在：
 if (PhoneApplicationService.Current.State.ContainsKey("address"))
 {
        string address = PhoneApplicationService.Current.State["address"] as string;
 }
