介绍

重新想象 Windows 8 Store Apps 之 信息

获取包信息

获取系统信息

获取硬件信息

获取即插即用（PnP: Plug and Play）的设备的信息

获取常用设备信息

示例

1、演示如何获取 app 的 package 信息

Information/PackageInfo.xaml.cs

/* * 演示如何获取 app 的 package 信息 */using System;using Windows.ApplicationModel;using Windows.UI.Xaml.Controls;using Windows.UI.Xaml.Navigation;namespace XamlDemo.Information{public sealed partial class PackageInfo : Page{public PackageInfo（）{this.InitializeComponent（）;}protected override void OnNavigatedTo（NavigationEventArgs e）{Package package = Package.Current;PackageId packageId = package.Id;lblMsg.Text = "Name: " + packageId.Name; // 包名lblMsg.Text += Environment.NewLine;lblMsg.Text += "Version: " + packageId.Version; // 版本信息lblMsg.Text += Environment.NewLine;lblMsg.Text += "Architecture: " + packageId.Architecture; // 支持的 cpu 类型（X86, Arm, X64, Neutral（均支持）, Unknown）lblMsg.Text += Environment.NewLine;lblMsg.Text += "Publisher: " + packageId.Publisher; // 发布者lblMsg.Text += Environment.NewLine;lblMsg.Text += "PublisherId: " + packageId.PublisherId; // 发布者 idlblMsg.Text += Environment.NewLine;lblMsg.Text += "FullName: " + packageId.FullName; // 包全名（Name + Version + Architecture + PublisherId）lblMsg.Text += Environment.NewLine;lblMsg.Text += "FamilyName: " + packageId.FamilyName; // 包系列名（Name + PublisherId）lblMsg.Text += Environment.NewLine;lblMsg.Text += "Installed Location Path: " + package.InstalledLocation.Path; // 包的安装路径}}}

2、演示如何获取系统的相关信息

Information/SystemInfo.xaml.cs

/* * 演示如何获取系统的相关信息 */using System;using System.Globalization;using System.Threading.Tasks;using Windows.Devices.Enumeration.Pnp;using Windows.UI.Xaml.Controls;using Windows.UI.Xaml.Navigation;using System.Linq;namespace XamlDemo.Information{public sealed partial class SystemInfo : Page{public SystemInfo（）{this.InitializeComponent（）;}protected async override void OnNavigatedTo（NavigationEventArgs e）{lblMsg.Text += "CPU 核心数量：" + Environment.ProcessorCount.ToString（）;lblMsg.Text += Environment.NewLine;lblMsg.Text += "系统自上次启动以来所经过的毫秒数：" + Environment.TickCount;lblMsg.Text += Environment.NewLine;lblMsg.Text += "当前语言：" + CultureInfo.CurrentCulture.DisplayName;lblMsg.Text += Environment.NewLine;lblMsg.Text += "当前时间：" + DateTime.Now.ToString（"yyyy年MM月dd日 HH:mm:ss"） + " 星期" + "日一二三四五六七".Substring（（int）DateTime.Now.DayOfWeek, 1）;lblMsg.Text += Environment.NewLine;lblMsg.Text += "当前时区：" + "UTC" + DateTimeOffset.Now.ToString（"%K"）;lblMsg.Text += Environment.NewLine;lblMsg.Text += "当前系统版本号：" + （await GetWindowsVersionAsync（））.ToString（）;}#region 获取当前系统版本号，摘自：http://attackpattern.com/2013/03/device-information-in-windows-8-store-apps/public static async Task<string> GetWindowsVersionAsync（）{var hal = await GetHalDevice（DeviceDriverVersionKey）;if （hal == null || ！hal.Properties.ContainsKey（DeviceDriverVersionKey））return null;var versionParts = hal.Properties[DeviceDriverVersionKey].ToString（）.Split（"."）;return string.Join（".", versionParts.Take（2）.ToArray（））;}private static async Task<PnpObject> GetHalDevice（params string[] properties）{var actualProperties = properties.Concat（new[] { DeviceClassKey }）;var rootDevices = await PnpObject.FindAllAsync（PnpObjectType.Device,actualProperties, RootQuery）;foreach （var rootDevice in rootDevices.Where（d => d.Properties ！= null && d.Properties.Any（）））{var lastProperty = rootDevice.Properties.Last（）;if （lastProperty.Value ！= null）if （lastProperty.Value.ToString（）.Equals（HalDeviceClass））return rootDevice;}return null;}const string DeviceClassKey = "{A45C254E-DF1C-4EFD-8020-67D146A850E0},10";const string DeviceDriverVersionKey = "{A8B865DD-2E3D-4094-AD97-E593A70C75D6},3";const string RootContainer = "{00000000-0000-0000-FFFF-FFFFFFFFFFFF}";const string RootQuery = "System.Devices.ContainerId:="" + RootContainer + """;const string HalDeviceClass = "4d36e966-e325-11ce-bfc1-08002be10318";#endregion}}

3、演示如何获取硬件相关的信息

Information/HardwareInfo.xaml.cs

/* * 演示如何获取硬件相关的信息 */using System;using Windows.Storage.Streams;using Windows.System.Profile;using Windows.UI.Xaml.Controls;using Windows.UI.Xaml.Navigation;namespace XamlDemo.Information{public sealed partial class HardwareInfo : Page{public HardwareInfo（）{this.InitializeComponent（）;}protected override void OnNavigatedTo（NavigationEventArgs e）{HardwareToken hardwareToken = HardwareIdentification.GetPackageSpecificToken（null）;lblMsg.Text = "Id: " + Buffer2Base64（hardwareToken.Id）; // 硬件 IDlblMsg.Text += Environment.NewLine;lblMsg.Text += Environment.NewLine;lblMsg.Text += "Signature: " + Buffer2Base64（hardwareToken.Signature）; // 硬件签名lblMsg.Text += Environment.NewLine;lblMsg.Text += Environment.NewLine;lblMsg.Text += "Certificate: " + Buffer2Base64（hardwareToken.Certificate）; // 硬件证书}private string Buffer2Base64（IBuffer buffer）{using （var dataReader = DataReader.FromBuffer（buffer））{try{var bytes = new byte[buffer.Length];dataReader.ReadBytes（bytes）;return Convert.ToBase64String（bytes）;}catch （Exception ex）{return ex.ToString（）;}}}}}
