Valore della proprietà

X509Certificate2Collection

Raccolta di certificati.

Esempio

Questa sezione contiene due esempi. Il primo esempio illustra come aprire gli archivi X.509 standard e elencare il numero di certificati in ogni.

Il secondo esempio illustra come aggiungere e rimuovere singoli certificati e intervalli di certificati.

Esempio 1

Questo esempio tenta di aprire ogni archivio standard in ogni posizione standard nel computer corrente. Stampa un riepilogo che mostra se ogni archivio esiste e, in tal caso, il numero di certificati che contiene.

L'esempio crea un X509Store oggetto per ogni combinazione di nome standard e posizione standard. Chiama il metodo con il flag, che apre l'archivio OpenOpenFlags.OpenExistingOnly fisico solo se esiste già. Se l'archivio fisico esiste, nell'esempio vengono usate le Nameproprietà , Locatione Certificates per visualizzare il numero di certificati nell'archivio.

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);

Esempio 2

Questo esempio apre un archivio certificati X.509, aggiunge ed elimina i certificati e quindi chiude l'archivio. Si presuppone che siano presenti tre certificati da aggiungere e rimuovere da un archivio locale.

Commenti

Questo metodo restituisce uno snapshot dell'archivio certificati X.509. Si noti che le operazioni successive Add o Remove eseguite nell'archivio non avranno alcun effetto sulla raccolta restituita. Questo snapshot viene ricalcolato ogni volta che viene chiamata la proprietà, quindi l'uso di questa proprietà all'interno di una funzione iterativa non è consigliato.

Si applica a
