Esempio

Nell'esempio di codice seguente viene illustrato come scrivere in un oggetto autenticato SslStream.

static void ProcessClient (TcpClient client)
{
    // A client has connected. Create the
    // SslStream using the client's network stream.
    SslStream sslStream = new SslStream(
        client.GetStream(), false);
    // Authenticate the server but don't require the client to authenticate.
    try
    {
        sslStream.AuthenticateAsServer(serverCertificate, clientCertificateRequired: false, checkCertificateRevocation: true);

        // Display the properties and settings for the authenticated stream.
        DisplaySecurityLevel(sslStream);
        DisplaySecurityServices(sslStream);
        DisplayCertificateInformation(sslStream);
        DisplayStreamProperties(sslStream);

        // Set timeouts for the read and write to 5 seconds.
        sslStream.ReadTimeout = 5000;
        sslStream.WriteTimeout = 5000;
        // Read a message from the client.
        Console.WriteLine("Waiting for client message...");
        string messageData = ReadMessage(sslStream);
        Console.WriteLine("Received: {0}", messageData);

        // Write a message to the client.
        byte[] message = Encoding.UTF8.GetBytes("Hello from the server.<EOF>");
        Console.WriteLine("Sending hello message.");
        sslStream.Write(message);
    }
    catch (AuthenticationException e)
    {
        Console.WriteLine("Exception: {0}", e.Message);
        if (e.InnerException != null)
        {
            Console.WriteLine("Inner exception: {0}", e.InnerException.Message);
        }
        Console.WriteLine ("Authentication failed - closing the connection.");
        sslStream.Close();
        client.Close();
        return;
    }
    finally
    {
        // The client stream will be closed with the sslStream
        // because we specified this behavior when creating
        // the sslStream.
        sslStream.Close();
        client.Close();
    }

Commenti

Questo metodo si blocca al termine dell'operazione. Per impedire il blocco al termine dell'operazione, utilizzare il BeginWrite metodo .

Non è possibile chiamare questo metodo fino a quando non è stata eseguita correttamente l'autenticazione. Per autenticare chiamare uno dei AuthenticateAsClientmetodi , o BeginAuthenticateAsClient, AuthenticateAsServer. BeginAuthenticateAsServer

La SslStream classe non supporta più operazioni di scrittura simultanee.
