Exemples

L’exemple de code suivant ouvre le magasin de certificats personnel de l’utilisateur actuel, permet à l’utilisateur de sélectionner un certificat, puis écrit les informations de certificat et de chaîne de certificats dans la console. La sortie dépend du certificat que vous sélectionnez.

//Output chain element information.
Console::WriteLine( "Chain Element Information" );
Console::WriteLine( "Number of chain elements: {0}", ch->ChainElements->Count );
Console::WriteLine( "Chain elements synchronized? {0} {1}", ch->ChainElements->IsSynchronized, Environment::NewLine );
System::Collections::IEnumerator^ myEnum = ch->ChainElements->GetEnumerator();
while ( myEnum->MoveNext() )
{
   X509ChainElement ^ element = safe_cast<X509ChainElement ^>(myEnum->Current);
   Console::WriteLine( "Element issuer name: {0}", element->Certificate->Issuer );
   Console::WriteLine( "Element certificate valid until: {0}", element->Certificate->NotAfter );
   Console::WriteLine( "Element certificate is valid: {0}", element->Certificate->Verify() );
   Console::WriteLine( "Element error status length: {0}", element->ChainElementStatus->Length );
   Console::WriteLine( "Element information: {0}", element->Information );
   Console::WriteLine( "Number of element extensions: {0}{1}", element->Certificate->Extensions->Count, Environment::NewLine );
   if ( ch->ChainStatus->Length > 1 )
   {
      for ( int index = 0; index < element->ChainElementStatus->Length; index++ )
      {
         Console::WriteLine( element->ChainElementStatus[ index ].Status );
         Console::WriteLine( element->ChainElementStatus[ index ].StatusInformation );
      }
   }
}

store->Close();

    //Output chain element information.
    Console.WriteLine ("Chain Element Information");
    Console.WriteLine ("Number of chain elements: {0}", ch.ChainElements.Count);

        Dim index As Integer
        For index = 0 To element.ChainElementStatus.Length
            Console.WriteLine(element.ChainElementStatus(index).Status)
            Console.WriteLine(element.ChainElementStatus(index).StatusInformation)
