获取用户名在Windows 10 C＃UWP万能的Windows应用程序 [英] Get UserName in a Windows 10 C# UWP Universal Windows app

问题描述

我与在Windows 10 UWP世界另一个简单的任务挣扎。

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

我只需要当前Windows用户的用户名。 Environment.UserName只是不UWP的事情。而且没有在网上搜索量至今已经协助。因此，我张贴在这里。

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.

有人吗？现在这是不可能的？

Anyone? Is this just not possible now?

感谢。

1. 添加用户帐户信息功能，为您的应用



2. 使用此代码获取用户的显示名称：

1. Add "User Account Information" capability to your app

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;
}
