在Windows 10 C＃UWP通用Windows应用程序中获取UserName

Question

I am struggling with yet another simple task in the Windows 10 UWP world.

I simply need the UserName of the current Windows user. Environment.UserName is just not a thing in UWP. And no amount of searching the web has helped so far. Hence my post here.

Anyone? Is this just not possible now?

Answer 1

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; } 

Answer 2

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);

Answer 3

You can also pickup the User who launched the app from the Application.OnLaunched method see here .

You still need to declare the User Information capability in you manifest though.

quick example (Ellipses denote non applicable generated code):

sealed partial class App : Application
{
    ... 
    protected override void OnLaunched(LaunchActivatedEventArgs e)
    {
        User currentUser = e.User;
        ... 
    }
    ...
}          

Answer 4

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

This will get you the full domain\\username.
