NegotiateStream.Flush Method ()

 

Causes any buffered data to be written to the underlying device.

Namespace:   System.Net.Security
Assembly:  System (in System.dll)

public override void Flush()

This method invokes Flush on the underlying stream.

The following code example demonstrates flushing the stream.

    public static void Main(String[] args)  
    {
        // Establish the remote endpoint for the socket.
        // For this example, use the local machine.
        IPHostEntry ipHostInfo = Dns.GetHostEntry(Dns.GetHostName());
        IPAddress ipAddress = ipHostInfo.AddressList[0];
        // Client and server use port 11000. 
        IPEndPoint remoteEP = new IPEndPoint(ipAddress,11000);
        // Create a TCP/IP socket.
       TcpClient client = new TcpClient();
        // Connect the socket to the remote endpoint.
        client.Connect(remoteEP);
        Console.WriteLine("Client connected to {0}.",
            remoteEP.ToString());
        // Ensure the client does not close when there is 
        // still data to be sent to the server.
        client.LingerState = (new LingerOption(true,0));
        // Request authentication.
        NetworkStream clientStream = client.GetStream();
        NegotiateStream authStream = new NegotiateStream(clientStream); 
        // Request authentication for the client only (no mutual authentication).
        // Authenicate using the client's default credetials.
        // Permit the server to impersonate the client to access resources on the server only.
        // Request that data be transmitted using encryption and data signing.
        authStream.AuthenticateAsClient(
             (NetworkCredential) CredentialCache.DefaultCredentials, 
             "",
             ProtectionLevel.EncryptAndSign,
             TokenImpersonationLevel.Impersonation);
        DisplayAuthenticationProperties(authStream);
        DisplayStreamProperties(authStream);
        if (authStream.CanWrite)
        {
             // Encode the test data into a byte array.
            byte[] message = System.Text.Encoding.UTF8.GetBytes("Hello from the client.");
            authStream.Write(message, 0, message.Length);
      authStream.Flush();
            Console.WriteLine("Sent {0} bytes.", message.Length);
     }
     // Close the client connection.
        authStream.Close();
        Console.WriteLine("Client closed.");
