Windows phone 7 获取wp7发布次数评级的消息框

最近我一直在尝试添加一个消息框，该消息框应该在某个时间间隔内弹出（例如应用程序启动次数）。此消息框也可以永久隐藏以防弹出

以下代码块可以放入任何现有应用程序中，并有助于提供上述功能：

在.xaml页面中，

public partial class MainPage : PhoneApplicationPage
{
    private static bool PerformedRatingPromptCheck = false;
    // Constructor

    public MainPage()
    {
        InitializeComponent();
    }
}

private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
    {
        if (!PerformedRatingPromptCheck)
        {
            PerformedRatingPromptCheck = true;

            int numAppLaunches = 0;
            IsolatedStorageSettings.ApplicationSettings.TryGetValue<int>("Rating_numAppLaunches", out numAppLaunches);

            int numNextRatingPrompt = 0;
            if (!IsolatedStorageSettings.ApplicationSettings.TryGetValue<int>("Rating_numNextRatingPrompt", out numNextRatingPrompt))
            {
                numNextRatingPrompt = 3;
            }

            if (numAppLaunches >= numNextRatingPrompt)
            {
                IsolatedStorageSettings.ApplicationSettings["Rating_numNextRatingPrompt"] = numNextRatingPrompt * 2;

                NotificationBox.ShowAgain("Enjoying the app?",
                        "Would you like to rate this app now, support us?",
                        "Ask me later",
                        false,
                        Surpressed => { },
                        "Rating_MsgPrompt",
                        new NotificationBoxCommand("yes", () => { new MarketplaceReviewTask().Show(); }),
                        new NotificationBoxCommand("no", () => { }));
            }

            IsolatedStorageSettings.ApplicationSettings["Rating_numAppLaunches"] = numAppLaunches + 1;
        }
    }

**//别忘了在xaml页面上添加此代码**

在.xaml.cs页面中，

public partial class MainPage : PhoneApplicationPage
{
    private static bool PerformedRatingPromptCheck = false;
    // Constructor

    public MainPage()
    {
        InitializeComponent();
    }
}

private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
    {
        if (!PerformedRatingPromptCheck)
        {
            PerformedRatingPromptCheck = true;

            int numAppLaunches = 0;
            IsolatedStorageSettings.ApplicationSettings.TryGetValue<int>("Rating_numAppLaunches", out numAppLaunches);

            int numNextRatingPrompt = 0;
            if (!IsolatedStorageSettings.ApplicationSettings.TryGetValue<int>("Rating_numNextRatingPrompt", out numNextRatingPrompt))
            {
                numNextRatingPrompt = 3;
            }

            if (numAppLaunches >= numNextRatingPrompt)
            {
                IsolatedStorageSettings.ApplicationSettings["Rating_numNextRatingPrompt"] = numNextRatingPrompt * 2;

                NotificationBox.ShowAgain("Enjoying the app?",
                        "Would you like to rate this app now, support us?",
                        "Ask me later",
                        false,
                        Surpressed => { },
                        "Rating_MsgPrompt",
                        new NotificationBoxCommand("yes", () => { new MarketplaceReviewTask().Show(); }),
                        new NotificationBoxCommand("no", () => { }));
            }

            IsolatedStorageSettings.ApplicationSettings["Rating_numAppLaunches"] = numAppLaunches + 1;
        }
    }
