SslStream.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 calling this method.

// Create a TCP/IP client socket. 
// machineName is the host running the server application.
TcpClient client = new TcpClient(machineName,443);
Console.WriteLine("Client connected.");
// Create an SSL stream that will close the client's stream.
SslStream sslStream = new SslStream(
    client.GetStream(), 
    false, 
    new RemoteCertificateValidationCallback (ValidateServerCertificate), 
    null
    );
// The server name must match the name on the server certificate. 
try 
{
    sslStream.AuthenticateAsClient(serverName);
} 
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.");
    client.Close();
    return;
}
// Encode a test message into a byte array. 
// Signal the end of the message using the "<EOF>".
byte[] messsage = Encoding.UTF8.GetBytes("Hello from the client.<EOF>");
// Send hello message to the server. 
sslStream.Write(messsage);
sslStream.Flush();
