Get UserName in a Windows 10 C# UWP Universal Windows app

1. Add "User Account Information" capability to your app in the Package.appxmanifest

2. Use this code to get user display name:

   private async void Page_Loaded(object sender, RoutedEventArgs e){    IReadOnlyList<User> users = await User.FindAllAsync();    var current = users.Where(p => p.AuthenticationStatus == UserAuthenticationStatus.LocallyAuthenticated &&                                 p.Type == UserType.LocalUser).FirstOrDefault();    // user may have username    var data = await current.GetPropertyAsync(KnownUserProperties.AccountName);    string displayName = (string)data;    //or may be authinticated using hotmail     if(String.IsNullOrEmpty(displayName))    {        string a = (string)await current.GetPropertyAsync(KnownUserProperties.FirstName);        string b = (string)await current.GetPropertyAsync(KnownUserProperties.LastName);        displayName = string.Format("{0} {1}", a, b);    }    text1.Text = displayName;}

// get usernamepublic string UserNameStr { get; set; } = WindowsIdentity.GetCurrent().Name;

This will get you the full domain\username.

As I can see, there is a User class available (UWP): https://msdn.microsoft.com/en-us/library/windows/apps/windows.system.user.aspx

Try this:

var users = await User.FindAllAsync(UserType.LocalUser);var name = await users.FirstOrDefault().GetPropertyAsync(KnownUserProperties.AccountName);
