Esempio

L'esempio di codice seguente illustra la visualizzazione del 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,
