Examples

Call the PackageManager.FindUsers method to enumerate the users who have installed a package. This example displays the information in the PackageUserInformation.UserSecurityId property.

using System.Security.Principal;

private static void DisplayPackageUsers(
    Windows.Management.Deployment.PackageManager packageManager, 
    Windows.ApplicationModel.Package package)
{
    IEnumerable<Windows.Management.Deployment.PackageUserInformation> packageUsers =

    Console.Write("Users: ");

    foreach (var packageUser in packageUsers)
    {
        Console.Write("{0} ", SidToAccountName(packageUser.UserSecurityId));
    }

    Console.WriteLine();
}

            {

                stringSid = stringSid + L"\\" + name;
            }
        }
        catch ( ... )
        {
            // do nothing, original SID will be used.
        }

        delete [] domainName;
        delete [] name;
