Get The Username/User Id Of Currently Logged In Us

问题:

I want to get the username or user id of the currently logged in user in a UWP app. Below is the code that I am using but it returns null.

var current = users.Where(p => p.AuthenticationStatus == UserAuthenticationStatus.LocallyAuthenticated && p.Type == UserType.LocalUser).FirstOrDefault();
var data = await current.GetPropertyAsync(KnownUserProperties.AccountName);
Username = (string)data;

回答1:

var users = await User.FindAllAsync(UserType.LocalUser);
var user = (string) await users.FirstOrDefault().GetPropertyAsync(KnownUserProperties.AccountName);
var domain = "";
var host = "";

if (string.IsNullOrEmpty(user))
{
var domainWithUser = (string) await users.FirstOrDefault().GetPropertyAsync(KnownUserProperties.DomainName);
domain = domainWithUser.Split('\\')[0];
user = domainWithUser.Split('\\')[1];
}
