/* * 演示如何获取用户的信息 * * 需要在 Package.appxmanifest 中的“成果”中勾选“用户账户信息”，即 <Capability /> * 如上配置之后，即可通过 api 获取用户的相关信息（系统会自转动出权限请求对话框） * * User - 用户 * FindAllAsync() - 查找全部用户，也可以按照 UserType 和 UserAuthenticationStatus 来查找用户 * 颠末测试，其只能返回当前登录用户 * GetPropertyAsync(), GetPropertiesAsync() - 获取用户的指定属性 * 可获取的属性请参见 Windows.System.KnownUserProperties * GetPictureAsync() - 获取用户图片 * 图片规格有 64x64, 208x208, 424x424, 1080x1080 * NonRoamableId - 用户 id * 此 id 不成漫游 * UserType - 用户类型 * LocalUser, RemoteUser, LocalGuest, RemoteGuest * UserAuthenticationStatus - 用户的身份验证状态 * Unauthenticated, LocallyAuthenticated, RemotelyAuthenticated * CreateWatcher() - 返回 UserWatcher 东西，用于监听用户的状态变革 * 本例不做演示 */ using System; using System.Collections.Generic; using Windows.Foundation.Collections; using Windows.Storage.Streams; using Windows.System; using Windows.UI.Xaml.Controls; using Windows.UI.Xaml.Media.Imaging; using Windows.UI.Xaml.Navigation; namespace Windows10.UserAndAccount { public sealed partial class UserInfo : Page { public UserInfo() { this.InitializeComponent(); } protected async override void OnNavigatedTo(NavigationEventArgs e) { base.OnNavigatedTo(e); // 我这里测试的功效是：返回的调集中只有一个元素，就是当前的登录用户 IReadOnlyList<User> users = await User.FindAllAsync(); // 系统会自转动出权限请求对话框 User user = users?[0]; if (user != null) { // 对付获取用户的 NonRoamableId, Type, AuthenticationStatus 信息，差别意权限请求也是可以的 string result = "NonRoamableId: " + user.NonRoamableId + "\n"; result += "Type: " + user.Type.ToString() + "\n"; result += "AuthenticationStatus: " + user.AuthenticationStatus.ToString() + "\n"; // 对付获取用户的如下信息及图片，，则必需要同意权限请求 string[] desiredProperties = new string[] { KnownUserProperties.DisplayName, KnownUserProperties.FirstName, KnownUserProperties.LastName, KnownUserProperties.ProviderName, KnownUserProperties.AccountName, KnownUserProperties.GuestHost, KnownUserProperties.PrincipalName, KnownUserProperties.DomainName, KnownUserProperties.SessionInitiationProtocolUri, }; // 获取用户的指定属性调集 IPropertySet values = await user.GetPropertiesAsync(desiredProperties); foreach (string property in desiredProperties) { result += property + ": " + values[property] + "\n"; } // 获取用户的指定属性 // object displayName = await user.GetPropertyAsync(KnownUserProperties.DisplayName); lblMsg.Text = result; // 获取用户的图片 IRandomAccessStreamReference streamReference = await user.GetPictureAsync(UserPictureSize.Size64x64); if (streamReference != null) { IRandomAccessStream stream = await streamReference.OpenReadAsync(); BitmapImage bitmapImage = new BitmapImage(); bitmapImage.SetSource(stream); imageProfile.Source = bitmapImage; } } } } }
