Beispiele

Im folgenden Beispiel wird eine X509Certificate aus einer angegebenen Zertifizierungsdatei erstellt.

using namespace System;
using namespace System::Security::Cryptography::X509Certificates;
int main()
{
   
   // The path to the certificate.
   String^ Certificate = "Certificate.cer";
   
   // Load the certificate into an X509Certificate object.
   X509Certificate^ cert = X509Certificate::CreateFromCertFile( Certificate );
   
   // Get the value.
   String^ resultsTrue = cert->ToString( true );
   
   // Display the value to the console.
   Console::WriteLine( resultsTrue );
   
   // Get the value.
   String^ resultsFalse = cert->ToString( false );
   
   // Display the value to the console.
   Console::WriteLine( resultsFalse );
}
