Voorbeelden

Deze sectie bevat twee voorbeelden. In het eerste voorbeeld ziet u hoe u standaard X.509-archieven kunt openen en het aantal certificaten in elk certificaat kunt weergeven.

In het tweede voorbeeld ziet u hoe u afzonderlijke certificaten en bereiken met certificaten kunt toevoegen en verwijderen.

Voorbeeld 1

In dit voorbeeld wordt geprobeerd om elke standaardopslag te openen op elke standaardlocatie op de huidige computer. Er wordt een samenvatting afgedrukt waarin wordt aangegeven of elk archief bestaat en, als dat het is, het aantal certificaten dat het bevat.

In het voorbeeld wordt een X509Store object gemaakt voor elke combinatie van standaardnaam en standaardlocatie. Hiermee wordt de Open methode aangeroepen met de OpenFlags.OpenExistingOnly vlag, waarmee het fysieke archief alleen wordt geopend als deze al bestaat. Als het fysieke archief bestaat, gebruikt het voorbeeld de Name, Locationen Certificates eigenschappen om het aantal certificaten in het archief weer te geven.

public class Example
{
    static void Main()
    {
        Console.WriteLine("\r\nExists Certs Name and Location");
        Console.WriteLine("------ ----- -------------------------");

        foreach (StoreLocation storeLocation in (StoreLocation[])
            Enum.GetValues(typeof(StoreLocation)))
        {
            foreach (StoreName storeName in (StoreName[])
                Enum.GetValues(typeof(StoreName)))
            {
                X509Store store = new X509Store(storeName, storeLocation);

                try
                {
                    store.Open(OpenFlags.OpenExistingOnly);

                    Console.WriteLine("Yes    {0,4}  {1}, {2}",
                        store.Certificates.Count, store.Name, store.Location);
                }
                catch (CryptographicException)
                {
                    Console.WriteLine("No           {0}, {1}",
                        store.Name, store.Location);
                }
            }
            Console.WriteLine();
        }
    }

Voorbeeld 2

In dit voorbeeld wordt een X.509-certificaatarchief geopend, worden certificaten toegevoegd en verwijderd en wordt het archief gesloten. Hierbij wordt ervan uitgegaan dat u drie certificaten hebt om toe te voegen aan en te verwijderen uit een lokaal archief.
