通常情况下我们需要知道用户设备的一些信息：deviceId, os version, 设备制造商, 设备型号。

下面的代码用于获取设备的信息。（注：代码源于网络）

DeviceInfoHelper	public class DeviceInfoHelper	{		public async static Task
     
       GetDeviceInfoAsync()		{			DeviceInfo info = new DeviceInfo();			info.DeviceID = GetDeviceID();			info.DeviceOS = (await GetWindowsVersionAsync()) + "-" +				(await GetDeviceManufacturerAsync()) + "-" +				(await GetDeviceModelAsync()) + "-" +				(await GetDeviceCategoryAsync());			return info;		}		public static string GetDeviceID()		{			HardwareToken packageSpecificToken = HardwareIdentification.GetPackageSpecificToken(null);			var hardwareId = packageSpecificToken.Id;			var _internalId = "";			var dataReader = Windows.Storage.Streams.DataReader.FromBuffer(hardwareId);			var array = new byte[hardwareId.Length];			dataReader.ReadBytes(array);			for (var i = 0; i < array.Length; i++)			{				_internalId += array[i].ToString();			}			return _internalId;		}		const string ItemNameKey = "System.ItemNameDisplay";		const string ModelNameKey = "System.Devices.ModelName";		const string ManufacturerKey = "System.Devices.Manufacturer";		const string DeviceClassKey = "{A45C254E-DF1C-4EFD-8020-67D146A850E0},10";		const string PrimaryCategoryKey = "{78C34FC8-104A-4ACA-9EA4-524D52996E57},97";		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";		public static async Task
      
        GetProcessorArchitectureAsync()		{			var halDevice = await GetHalDevice(ItemNameKey);			if (halDevice != null && halDevice.Properties[ItemNameKey] != null)			{				var halName = halDevice.Properties[ItemNameKey].ToString();				if (halName.Contains("x64")) return ProcessorArchitecture.X64;				if (halName.Contains("ARM")) return ProcessorArchitecture.Arm;				return ProcessorArchitecture.X86;			}			return ProcessorArchitecture.Unknown;		}		public static Task
       
         GetDeviceManufacturerAsync()		{			return GetRootDeviceInfoAsync(ManufacturerKey);		}		public static Task
        
          GetDeviceModelAsync()		{			return GetRootDeviceInfoAsync(ModelNameKey);		}		public static Task
         
           GetDeviceCategoryAsync()		{			return GetRootDeviceInfoAsync(PrimaryCategoryKey);		}		public static async Task
          
            GetWindowsVersionAsync() { // There is no good place to get this. // The HAL driver version number should work unless you're using a custom HAL... 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
           
             GetRootDeviceInfoAsync(string propertyKey) { var pnp = await PnpObject.CreateFromIdAsync(PnpObjectType.DeviceContainer, RootContainer, new[] { propertyKey }); return (string)pnp.Properties[propertyKey]; } private static async Task
            
              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; } } public class DeviceInfo { public string DeviceID { get; set; } public string DeviceOS { get; set; } }
            
           
          
         
        
       
      
     

调用：

Callervar deviceInfo = await DeviceInfoHelper.GetDeviceInfoAsync();// DeviceID: 307416080***************************************************// DeviceOS: 6.2-Microsoft Corporation-Surface with Windows RT-Computer.Tablet

可以看到我的设备是一台Sruface平板。
