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;
