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
*/ using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls; namespace Demo.Feature
{
public partial class Orientation : PhoneApplicationPage
{
public Orientation()
{
InitializeComponent(); this.SupportedOrientations = SupportedPageOrientation.PortraitOrLandscape;
this.OrientationChanged += new EventHandler<OrientationChangedEventArgs>(Orientation_OrientationChanged);
} void Orientation_OrientationChanged(object sender, OrientationChangedEventArgs e)
{
if ((e.Orientation & PageOrientation.Portrait) == (PageOrientation.Portrait))
{
MessageBox.Show("竖放");
}
else
{
MessageBox.Show("横放");
}
}
}
}

2、演示如何实现程序的本地化
Localization.xaml

<phone:PhoneApplicationPage
x:Class="Demo.Feature.Localization"
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"> <phone:PhoneApplicationPage.Resources>
<!--
注:AppResources 里的类和构造函数需要 public 的要手动改成 public
-->
<resources:AppResources xmlns:resources="clr-namespace:Demo.Resources" x:Key="MyLocalization" />
</phone:PhoneApplicationPage.Resources> <Grid x:Name="LayoutRoot" Background="Transparent">
<StackPanel Orientation="Vertical"> <TextBlock Name="lblMsg" /> <!--
xaml 方式应用本地化
-->
<TextBlock Text="{Binding Path=Software, Source={StaticResource MyLocalization}}" /> </StackPanel>
</Grid> </phone:PhoneApplicationPage>

Localization.xaml.cs

/*
* 演示如何本地化应用程序,相关资源文件在 Resources 目录下
*
* 注:本地化应用程序标题(标题分为两种:应用程序列表中的标题和“磁贴”上的应用程序标题,它们可以不同)请参看 http://msdn.microsoft.com/en-us/library/ff967550(v=vs.92).aspx
*/ using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls; using Demo.Resources; namespace Demo.Feature
{
public partial class Localization : PhoneApplicationPage
{
public Localization()
{
InitializeComponent(); // 代码方式应用本地化
lblMsg.Text = AppResources.Network;
}
}
}

3、演示如何提供支持试用体验的应用程序
TrialExperience.xaml

<phone:PhoneApplicationPage
x:Class="Demo.Feature.TrialExperience"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

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">
<StackPanel Orientation="Vertical"> <Button Name="btnTrial" Content="试用版可用的功能" Click="btnTrial_Click" /> <Button Name="btnNormal" Content="正式版里才有的功能" Click="btnNormal_Click" /> <Button Name="btnBuy" Content="购买正式版" Click="btnBuy_Click" /> </StackPanel>
</Grid> </phone:PhoneApplicationPage>

TrialExperience.xaml.cs

/*
* 演示如何在收费应用程序中加入试用体验
*
* LicenseInformation - 应用程序的许可证信息
* IsTrial() - 是否是试用版
*/ using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls; using Microsoft.Phone.Marketplace;
using Microsoft.Phone.Tasks; namespace Demo.Feature
{
public partial class TrialExperience : PhoneApplicationPage
{
private static LicenseInformation _licenseInfo = new LicenseInformation(); 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)
{
MessageBox.Show("正式版里才有的功能");
} private void btnBuy_Click(object sender, RoutedEventArgs e)
{
// 购买的话,直接打开应用程序在商店的详细页就好
MarketplaceDetailTask marketPlaceDetailTask = new MarketplaceDetailTask();
marketPlaceDetailTask.Show();
}
}
}

4、演示如何使用系统主题资源
ThemeResources.xaml

<phone:PhoneApplicationPage
x:Class="Demo.Feature.ThemeResources"
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="使用系统主题资源" Style="{StaticResource PhoneTextExtraLargeStyle}" /> <HyperlinkButton Content="全部系统主题资源" NavigateUri="http://msdn.microsoft.com/en-us/library/ff769552(v=vs.92)" TargetName="_blank" /> </Grid> </phone:PhoneApplicationPage>

5、演示如何实现本地数据的加密解密
EncryptData.xaml

<phone:PhoneApplicationPage
x:Class="Demo.Feature.EncryptData"
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="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
*/ using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls; using System.Security.Cryptography;
using System.Text; namespace Demo.Feature
{
public partial class EncryptData : PhoneApplicationPage
{
private string _base64 = ""; public EncryptData()
{
InitializeComponent(); EncryptDemo(); DecryptDemo();
} private void EncryptDemo()
{
byte[] plainText = Encoding.UTF8.GetBytes("webabcd");
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);
byte[] plainText = ProtectedData.Unprotect(protectedData, null); MessageBox.Show("解密后的数据:" + Environment.NewLine + Encoding.UTF8.GetString(plainText, , plainText.Length));
}
}
}
