Windows Phone 7 系统信息获取示例-优快云博客

本文介绍如何使用DispatcherTimer定时获取Windows Phone 7 (WP7) 设备的系统信息，包括设备制造商、名称、ID等，并展示如何在UI上实时更新这些信息。

假设你现在需要从WP7手机上获取一些系统信息，以便确认当前系统是否满足游戏或应用程序的最小硬件需求。轩辕在将给各位演示下实现这个功能有多么的简单。因为轩辕目前还没有拿到WP7手机，所以这篇文章将在模拟器上展开系统信息获取的实现。

下面是我们的示例将要获取的系统信息：

设备厂商
设备名称
设备ID
固件版本
硬件版本
总内存
应用程序当前使用内存
应用程序使用内存峰值

在下面这个示例中，轩辕将使用DispatcherTimer计时器每三秒获取一些系统信息，标将上面的列出的信息在8个textblock控件中展现出来。下面为应用程序的展现截图：

下面是XAML的代码：

接下来让我们写一些代码来获取系统信息。首先我们需要创建一个DispatcherTimer计时器对象。

DispatcherTimer timer;

在使用DispatcherTimer对象时你需要在项目中引用System.Windows.Threading这个命名空间。

接下来我们需要声明一个字符串变量以展现Device ID。

public static string val;

因为通过系统函数返回的Device ID是以Byte类型返回的，所有我们需要将Device ID转化为字符串类型进行呈现。

public static byte [] GetDeviceUniqueID()
{
    byte [] result = null ;
    object uniqueId;
    if (DeviceExtendedProperties.TryGetValue( " DeviceUniqueId " , out uniqueId))
   {
       result = ( byte [])uniqueId;
   }
   val = Convert.ToBase64String(result);
    return result;
}

完成上面的步骤后，我们就需要在页面的构造函数中启动计时器，以便定时获取设备系统信息了。下面是构造函数中的部分代码：

timer = new DispatcherTimer();
timer.Interval = new TimeSpan( 0 , 0 , 3 );
timer.Tick += new EventHandler(timer_Tick);
timer.Start();
GetDeviceUniqueID();

下面是计时器的定时程序：

void timer_Tick( object sender, EventArgs e)
{

   try
   {
    textBlock2.Text = DeviceExtendedProperties.GetValue( " DeviceManufacturer " ).ToString();
    textBlock4.Text = DeviceExtendedProperties.GetValue( " DeviceName " ).ToString();
    textBlock6.Text = val;
    textBlock8.Text = DeviceExtendedProperties.GetValue( " DeviceFirmwareVersion " ).ToString();
    textBlock10.Text = DeviceExtendedProperties.GetValue( " DeviceHardwareVersion " ).ToString();
    textBlock12.Text = DeviceExtendedProperties.GetValue( " DeviceTotalMemory " ).ToString();
    textBlock14.Text = DeviceExtendedProperties.GetValue( " ApplicationCurrentMemoryUsage " ).ToString();
    textBlock16.Text = DeviceExtendedProperties.GetValue( " ApplicationPeakMemoryUsage " ).ToString();
   }
    catch (Exception ex)
   {

//
}
}

我们可以使用DeviceExtendedProperties这个类来获取WP7设备的系统属性，关于该类的更多信息你可以参考MSDN的相关文档，地址如下：

http://msdn.microsoft.com/en-us/library/ff941122(v=VS.92).aspx

在模拟器中启动程序后，我们就可以看到文章最上面的系统信息显示了。因为我们使用的是模拟器，所有Device ID是并不是一个真实的硬件唯一标识。如果在WP7真机上运行该程序，那么Device ID、硬件版本、固件版本都会是真实值。尝试下吧.............
