X509Certificate.CreateFromCertFile(String) Methode

Definitie

Let op

Loading certificate data through the constructor or Import is obsolete. Use X509CertificateLoader instead to load certificates.

Hiermee maakt u een X.509v3-certificaat op basis van het opgegeven pkCS7-ondertekende bestand.

Voorbeelden

In het volgende voorbeeld wordt een X509Certificate van een opgegeven certificeringsbestand gemaakt.

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.
      Dim resultsFalse As String = cert.ToString(False)
      
      ' Display the value to the console.
      Console.WriteLine(resultsFalse)
   End Sub  
End Class

Opmerkingen

ASN.1 DER is de enige certificaatindeling die door deze klasse wordt ondersteund.

Note

Het certificaatbestand is niet beperkt tot .cer bestanden. Elk pkCS7-ondertekend bestand kan worden gebruikt, inclusief een Authenticode-ondertekend PFX-bestand.
