Esempio

Nell'esempio di codice seguente viene illustrato come visualizzare il certificato restituito da questa proprietà.

   static void DisplayCertificateInformation( SslStream^ stream )

         Console::WriteLine( L"Local cert was issued to {0} and is valid from {1} until {2}.", 
             localCertificate->Subject, 
             localCertificate->GetEffectiveDateString(), 
             localCertificate->GetExpirationDateString() );
      }
