L’exemple suivant crée un X509Certificate fichier de certification spécifié.

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 );
}

using System;

        // Display the value to the console.
        Console.WriteLine(resultsFalse);
    }
}

Imports System.Security.Cryptography.X509Certificates




Public Class X509
   
   
   Public Shared Sub Main()
      
      ' The path to the certificate.
      Dim Certificate As String = "Certificate.cer"

      Dim cert As X509Certificate = X509Certificate.CreateFromCertFile(Certificate)

Remarques

ASN.1 DER est le seul format de certificat pris en charge par cette classe.

Notes

Le fichier de certificat n’est pas limité aux fichiers .cer. Tout fichier signé PKCS7 peut être utilisé, y compris un fichier .pfx signé Authenticode.
