NavigationService.Navigate(
new Uri("/Page1.xaml?para1=dat1&para2=dat2", UriKind.Relative));

---------------End--------------------------

---------------程式碼--------------------------

        void Page1_Loaded(object sender, RoutedEventArgs e)
        {
            string dat = NavigationContext.QueryString["para1"];
            this.textBox1.Text = dat;
        }
---------------End--------------------------


---------------程式碼--------------------------

App.xaml.cs：
  public partial class App : Application
    {
        /// <summary>
        /// Provides easy access to the root frame of the Phone Application.
        /// </summary>
        /// <returns>The root frame of the Phone Application.</returns>
        public PhoneApplicationFrame RootFrame { get; private set; }
        public string globalData1 = "";
---------------End--------------------------

---------------程式碼--------------------------

Page1.xaml.cs：
        private void button1_Click(object sender, RoutedEventArgs e)
        {
            (App.Current as App).globalData1 = this.textBox2.Text;
        }
---------------End--------------------------


---------------程式碼--------------------------

MainPage1.xaml.cs：
        private void button3_Click(object sender, RoutedEventArgs e)
        {
            this.textBox2.Text = (App.Current as App).globalData1;
        }
---------------End--------------------------


-----------------程式碼-------------
App.Xaml.cs：
     private void Application_Deactivated(object sender, DeactivatedEventArgs e)
        {
            PhoneApplicationService.Current.State["globalData1"] = globalData1;
        }
----------------End-------------

同時，在應用程式從凍結模式返回時，將資料還原：

-----------------程式碼-------------

App.Xaml.cs：
        private void Application_Activated(object sender, ActivatedEventArgs e)
        {
            object obj;
            PhoneApplicationService.Current.State.TryGetValue("globalData1", out obj);
            if (obj != null) globalData1 = obj.ToString();
        }

-----------------End-------------
　　
--------------------程式碼----------------------
Page1.xaml.cs：
protected override void OnNavigatedFrom(System.Windows.Navigation.NavigationEventArgs e)
{
    this.State["textBox2"] = textBox2.Text;
    base.OnNavigatedFrom(e);
}

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
    object obj;
    this.State.TryGetValue("textBox2", out obj);
    if (obj != null) textBox2.Text = obj.ToString();

    base.OnNavigatedTo(e);
}
-------------------End----------------------

------------------程式碼------------------
MainPage.xaml.cs：
public MainPage()
{
    InitializeComponent();
    BackKeyPress += (ss,arg) => {
        if (MessageBox.Show("確定要離開???", "確認", MessageBoxButton.OKCancel) == MessageBoxResult.Cancel)
        {
            arg.Cancel = true;
        }
    };
}
-------------------End------------

------------------程式碼------------------

Page1 的Loaded事件：
public partial class Page1 : PhoneApplicationPage
{
    public Page1()
    {
        InitializeComponent();
        Loaded += new RoutedEventHandler(Page1_Loaded);
    }

    void Page1_Loaded(object sender, RoutedEventArgs e)
    {
        this.Storyboard1.Begin();
        …略…
    }
------------------End------------------


----------------程式碼-------------------------
Page1.xaml.cs：
public Page1()
{
    InitializeComponent();
    (…略…)
    OrientationChanged += (ss, arg) => {
        //可在這裡撰寫程式碼進行處理
    };
}
---------------End------------
