GenericPrincipal(IIdentity, String[]) Constructor

Definition

Initializes a new instance of the GenericPrincipal class from a user identity and an array of role names to which the user represented by that identity belongs.

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())

Parameters

identity
IIdentity

A basic implementation of IIdentity that represents any user.

roles
String[]

An array of role names to which the user represented by the identity parameter belongs.

Exceptions

The identity parameter is null.

Examples

The following code shows the use of the GenericPrincipal constructor. This code example is part of a larger example provided for the GenericPrincipal class.

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();
string[] roles = new string[10];
if (windowsIdentity.IsAuthenticated)
{
    // Add custom NetworkUser role.
    roles[0] = "NetworkUser";
}

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

if (windowsIdentity.IsSystem)
{
    // Add custom SystemUser role.
    roles[2] = "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 =
    new GenericIdentity(userName, authenticationType);

// Construct a GenericPrincipal object based on the generic identity
// and custom roles for the user.
GenericPrincipal genericPrincipal =
    new GenericPrincipal(genericIdentity, roles);
Dim roles(10) As String
Dim windowsIdentity As WindowsIdentity = windowsIdentity.GetCurrent()

If (windowsIdentity.IsAuthenticated) Then
    ' Add custom NetworkUser role.
    roles(0) = "NetworkUser"
End If

If (windowsIdentity.IsGuest) Then
    ' Add custom GuestUser role.
    roles(1) = "GuestUser"
End If


If (windowsIdentity.IsSystem) Then
    ' Add custom SystemUser role.
    roles(2) = "SystemUser"
End If

' Construct a GenericIdentity object based on the current Windows
' identity name and authentication type.
Dim authenticationType As String = windowsIdentity.AuthenticationType
Dim userName As String = windowsIdentity.Name
Dim genericIdentity = _
    New GenericIdentity(userName, authenticationType)

' Construct a GenericPrincipal object based on the generic identity
' and custom roles for the user.
Dim genericPrincipal As New GenericPrincipal(genericIdentity, roles)
