Exempel

I följande exempel skapas en X509Certificate från en angiven certifieringsfil.

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)

Kommentarer

ASN.1 DER är det enda certifikatformat som stöds av den här klassen.

Note

Certifikatfilen är inte begränsad till .cer filer. Alla PKCS7-signerade filer kan användas, inklusive en Authenticode-signerad .pfx-fil.
