示例
1、演示如何响应手机的方向变化
Orientation.xaml

<phone:PhoneApplicationPage

    x:Class="Demo.Feature.Orientation"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"

    xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"

    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

    FontFamily="{StaticResource PhoneFontFamilyNormal}"

    FontSize="{StaticResource PhoneFontSizeNormal}"

    Foreground="{StaticResource PhoneForegroundBrush}"

    SupportedOrientations="Portrait" Orientation="Portrait"

    mc:Ignorable="d" d:DesignHeight="768" d:DesignWidth="480"

    shell:SystemTray.IsVisible="True">

    <Grid x:Name="LayoutRoot" Background="Transparent">

        <TextBlock Text="改变手机方向，以查看演示效果" />

    </Grid>

</phone:PhoneApplicationPage>

Orientation.xaml.cs

/*

 * 演示如何捕获手机方向改变的事件

 *

 * PhoneApplicationPage - 页面

 *     SupportedOrientations - 支持的方向（Microsoft.Phone.Controls.SupportedPageOrientation 枚举）

 *         Portrait（竖）, Landscape（横）, PortraitOrLandscape（横竖）

 *     Orientation - 当前的方向（Microsoft.Phone.Controls.PageOrientation 枚举）

 *         None, Portrait, Landscape, PortraitUp, PortraitDown（目前不支持）, LandscapeLeft（PortraitUp 逆时针转到 Landscape）, LandscapeRight（PortraitUp 顺时针转到 Landscape）

 *     OrientationChanged - 方向改变后触发的事件（事件参数：OrientationChangedEventArgs）

 *

 * OrientationChangedEventArgs

 *     Orientation - 当前的页面方向

        private static bool _isTrial = true;

        public TrialExperience()

        {

            InitializeComponent();

            // 检查许可证，仅为测试用，实际项目中最好将此逻辑放到 Application_Launching 和 Application_Activated 中

            CheckLicense();

        }

        private void CheckLicense()

        {

#if DEBUG

            // 仅调试用，强行指定程序为试用版

            _isTrial = true;

#else

            // 获取当前安装到设备的版本是否为试用版

            _isTrial = _licenseInfo.IsTrial();

#endif

            // 如果是试用版则禁用正式版的功能

            if (_isTrial)

                btnNormal.IsEnabled = false;

        }

        private void btnTrial_Click(object sender, RoutedEventArgs e)

        {

            MessageBox.Show("试用版可用的功能");

        }

        private void btnNormal_Click(object sender, RoutedEventArgs e)

        <TextBlock Text="注：不同的应用程序有不同的密钥" />

    </Grid>

</phone:PhoneApplicationPage>

EncryptData.xaml.cs

/*

 * 演示如何对数据做加密解密

 *

 * ProtectedData - 用于加密解密数据

 *     Protect() - 加密数据

 *     Unprotect() - 解密数据

 *

 * 注：不同的应用程序有不同的密钥，所以本示例的加密解密仅针对同一应用程序有效。应用场景为：本地数据的加密解密

            byte[] protectedData = ProtectedData.Protect(plainText, null);

            _base64 = Convert.ToBase64String(protectedData);

            MessageBox.Show("字符串“webabcd”加密且base64后的数据：" + Environment.NewLine + _base64);

        }

        private void DecryptDemo()

        {

            byte[] protectedData = Convert.FromBase64String(_base64);
