Examples

The following code example demonstrates calling this method.

// Create a TCP/IP client socket.
// machineName is the host running the server application.
TcpClient^ client = gcnew TcpClient(machineName, 5000);
Console::WriteLine("Client connected.");
  
// Create an SSL stream that will close 
// the client's stream.
SslStream^ sslStream = gcnew SslStream(
    client->GetStream(), false,
    gcnew RemoteCertificateValidationCallback(ValidateServerCertificate),
    nullptr);
  
// The server name must match the name
// on the server certificate.
try
{
    sslStream->AuthenticateAsClient(serverName);
}
catch (AuthenticationException^ ex) 
{
    Console::WriteLine("Exception: {0}", ex->Message);
    if (ex->InnerException != nullptr)
    {
        Console::WriteLine("Inner exception: {0}", 
            ex->InnerException->Message);
    }

    Console::WriteLine("Authentication failed - "
        "closing the connection.");
    sslStream->Close();
    client->Close();
    return;
}
// Encode a test message into a byte array.
// Signal the end of the message using the "<EOF>".
array<Byte>^ messsage = Encoding::UTF8->GetBytes(
    "Hello from the client.<EOF>");
  
// Send hello message to the server.
sslStream->Write(messsage);
sslStream->Flush();

// Create a TCP/IP client socket.
// machineName is the host running the server application.
TcpClient client = new TcpClient(machineName,5000);
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();

Dim client = New TcpClient(machineName, 5000)

' Create an SSL stream that will close the client's stream.
Dim sslStream = New SslStream(
    client.GetStream(), False, 
    New RemoteCertificateValidationCallback(AddressOf ValidateServerCertificate), Nothing)

' The server name must match the name on the server certificate.
Try
    sslStream.AuthenticateAsClient(serverName)
Catch e As AuthenticationException
    Console.WriteLine("Exception: {0}", e.Message)

    If e.InnerException IsNot Nothing Then
        Console.WriteLine("Inner exception: {0}", e.InnerException.Message)
    End If

    Console.WriteLine("Authentication failed - closing the connection.")
    client.Close()
    Return
End Try

' Encode a test message into a byte array.
' Signal the end of the message using the "<EOF>".
Dim messsage As Byte() = Encoding.UTF8.GetBytes("Hello from the client.<EOF>")

' Send hello message to the server.
sslStream.Write(messsage)
sslStream.Flush()

Remarks

This method invokes Flush on the underlying stream.
