Příklady

Následující příklad vytvoří X509Certificate ze zadaného souboru certifikace.

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;
using System.Security.Cryptography.X509Certificates;

public class X509
{

    public static void 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);
    }
}

Imports System.Security.Cryptography.X509Certificates




Public Class X509
   
   
   Public Shared Sub Main()
      
      ' The path to the certificate.
      Dim Certificate As String = "Certificate.cer"
      
      ' Load the certificate into an X509Certificate object.
      Dim cert As X509Certificate = X509Certificate.CreateFromCertFile(Certificate)
      
      ' Get the value.
      Dim resultsTrue As String = cert.ToString(True)
      
      ' Display the value to the console.
      Console.WriteLine(resultsTrue)
      
      ' Get the value.

Poznámky

ASN.1 DER je jediný formát certifikátu podporovaný touto třídou.

Poznámka

Soubor certifikátu není omezen na soubory .cer. Můžete použít libovolný podepsaný soubor PKCS7, včetně souboru .pfx podepsaného authenticode.
