Definição

Namespace:

System.Security.Principal

Assembly:

System.Security.Claims.dll

Origem:

GenericPrincipal.cs

Inicializa uma nova instância da classe GenericPrincipal de uma identidade de usuário e uma matriz de nomes de função à qual pertence o usuário representado por essa identidade.

public:
 GenericPrincipal(System::Security::Principal::IIdentity ^ identity, cli::array <System::String ^> ^ roles);

public GenericPrincipal (System.Security.Principal.IIdentity identity, string[]? roles);

new System.Security.Principal.GenericPrincipal : System.Security.Principal.IIdentity * string[] -> System.Security.Principal.GenericPrincipal

Public Sub New (identity As IIdentity, roles As String())

Parâmetros

identity

IIdentity

Uma implementação básica de IIdentity que representa qualquer usuário.

roles

String[]

Uma matriz de nomes de função à qual o usuário representado pelo parâmetro identity pertence.

Exceções

ArgumentNullException

O parâmetro identity é null.

Exemplos

O código a seguir mostra o uso do GenericPrincipal construtor . Este exemplo de código faz parte de um exemplo maior fornecido para a GenericPrincipal classe .

WindowsIdentity^ windowsIdentity = WindowsIdentity::GetCurrent();
array<String^>^roles = gcnew array<String^>(10);
if ( windowsIdentity->IsAuthenticated )
{
   
   // Add custom NetworkUser role.
   roles[ 0 ] = L"NetworkUser";
}

if ( windowsIdentity->IsGuest )
{
   
   // Add custom GuestUser role.
   roles[ 1 ] = L"GuestUser";
}

if ( windowsIdentity->IsSystem )
{
   
   // Add custom SystemUser role.
   roles[ 2 ] = L"SystemUser";
}

// Construct a GenericIdentity object based on the current Windows
// identity name and authentication type.
String^ authenticationType = windowsIdentity->AuthenticationType;
String^ userName = windowsIdentity->Name;
GenericIdentity^ genericIdentity = gcnew GenericIdentity(
   userName,authenticationType );

// Construct a GenericPrincipal object based on the generic identity
// and custom roles for the user.
GenericPrincipal^ genericPrincipal = gcnew GenericPrincipal(
   genericIdentity,roles );

WindowsIdentity windowsIdentity = WindowsIdentity.GetCurrent();
