Property Value
An IPrincipal value representing the security context.The following code example shows how to set and retrieve the principal of a thread.
using namespace System; using namespace System::Security; using namespace System::Security::Permissions; using namespace System::Security::Principal; using namespace System::Threading; // Request permission to set thread principal. [assembly:SecurityPermissionAttribute( SecurityAction::RequestOptional,ControlPrincipal=true)]; [assembly:SecurityPermissionAttribute( SecurityAction::RequestMinimum,UnmanagedCode=true)]; int main() { array<String^>^rolesArray = {"managers","executives"}; try { // Set the principal to a new generic principal. Thread::CurrentPrincipal = gcnew GenericPrincipal( gcnew GenericIdentity( "Bob","Passport" ),rolesArray ); } catch ( SecurityException^ secureException ) { Console::WriteLine( "{0}: Permission to set Principal " "is denied.", secureException->GetType()->Name ); } IPrincipal^ threadPrincipal = Thread::CurrentPrincipal; Console::WriteLine( "Name: {0}\nIsAuthenticated: {1}" "\nAuthenticationType: {2}", threadPrincipal->Identity->Name, threadPrincipal->Identity->IsAuthenticated.ToString(), threadPrincipal->Identity->AuthenticationType ); }
