WP8頁面跳轉實現參數傳遞的多種方法（已完善）

方法一：通過WEB傳參方式進行傳參

開始跳轉頁：

NavigationService.Navigate(new Uri("/Page/MainPage/XXXXPage.xaml?Address="+address,UriKind.RelativeOrAbsolute));

轉入頁：

//此方法應該在頁面的Loaded方法體中實現

string address=NavigationContext.QueryString["address"];

判斷是否存在：

if (NavigationContext.QueryString.ContainsKey("address"))
            {
               string address=NavigationContext.QueryString["address"];
            }

方法二：通過獨立存儲方式進行傳參

開始跳轉頁：

IsolatedStorageSettings iss = IsolatedStorageSettings.ApplicationSettings;

iss["ImageSource"] = image.source;

NavigationService.Navigate(new Uri("/Page/MainPage/XXXXPage.xaml", UriKind.Relative));

轉入頁：

IsolatedStorageSettings iss = IsolatedStorageSettings.ApplicationSettings;

image.Source = (BitmapImage)iss["ImageSource"];

方法三：通過PhoneApplicationService來實現傳參

開始跳轉頁：

PhoneApplicationService myService = PhoneApplicationService.Current;

protected override void OnNavigatedFrom(NavigationEventArgs e){

      myService.State["address"] = "address";

      base.OnNavigatedFrom(e);

}

轉入頁：

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：通過App.xaml進行傳參（共享參數）

App.xaml:

定義一個或幾個用於傳參的對象，如public string Address{set;get;}

開始跳轉頁： 

(Application.Current as App).Address= "address";

轉入頁：

string address=(Application.Current as App).Address;

判斷是否存在：

 if (PhoneApplicationService.Current.State.ContainsKey("address"))
 {
string address = PhoneApplicationService.Current.State["address"] as string;
 }
