  • Referência

Definição

Namespace:
Windows.Management.Deployment
Editar

Localiza os usuários que instalaram o Pacote especificado.

public:
 virtual IIterable<PackageUserInformation ^> ^ FindUsers(Platform::String ^ packageFullName) = FindUsers;
IIterable<PackageUserInformation> FindUsers(winrt::hstring const& packageFullName);
public IEnumerable<PackageUserInformation> FindUsers(string packageFullName);
function findUsers(packageFullName)
Public Function FindUsers (packageFullName As String) As IEnumerable(Of PackageUserInformation)

Parâmetros

packageFullName
String

Platform::String

winrt::hstring

O nome completo do pacote. Esse parâmetro não pode ser nulo.

Retornos

IIterable<PackageUserInformation>

IEnumerable<PackageUserInformation>

Se o método for bem-sucedido, uma coleção enumerável de objetos de informações do usuário do pacote será retornada. Cada objeto PackageUserInformation nesta coleção contém o SID (identificador de segurança do usuário) de um usuário para o qual o pacote especificado está instalado. Se nenhum pacote com o nome completo do pacote especificado for encontrado, esse método retornará uma lista vazia.

Exemplos

Chame o método PackageManager.FindUsers para enumerar os usuários que instalaram um pacote. Este exemplo exibe as informações na propriedade PackageUserInformation.UserSecurityId .

using System.Security.Principal;
using Windows.Deployment.PackageManager;

private static void DisplayPackageUsers(
    PackageManager packageManager, 
    Windows.ApplicationModel.Package package)
{
    IEnumerable<PackageUserInformation> packageUsers = packageManager.FindUsers(
        package.Id.FullName);

    Console.Write("Users: ");

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

    Console.WriteLine();
}

private static string SidToAccountName(string sidString)
{
    SecurityIdentifier sid = new SecurityIdentifier(sidString);
    try
    {
        NTAccount account = (NTAccount)sid.Translate(typeof(NTAccount));
        return account.ToString();
    }
    catch (IdentityNotMappedException)
    {
        return sidString;
    }
}
