示例

下面的示例显示的属性SslStreamThe following example displays the properties of an SslStream.

static void AuthenticateCallback( IAsyncResult^ ar )
{
   SslStream^ stream = dynamic_cast<SslStream^>(ar->AsyncState);
   try
   {
      stream->EndAuthenticateAsClient( ar );
      Console::WriteLine( L"Authentication succeeded." );
      Console::WriteLine( L"Cipher: {0} strength {1}", stream->CipherAlgorithm, stream->CipherStrength );
      Console::WriteLine( L"Hash: {0} strength {1}", stream->HashAlgorithm, stream->HashStrength );
      Console::WriteLine( L"Key exchange: {0} strength {1}", stream->KeyExchangeAlgorithm, stream->KeyExchangeStrength );
      Console::WriteLine( L"Protocol: {0}", stream->SslProtocol );
      
      // Encode a test message into a byte array.
      // Signal the end of the message using the "<EOF>".
      array<Byte>^message = Encoding::UTF8->GetBytes( L"Hello from the client.<EOF>" );
      
      // Asynchronously send a message to the server.
      stream->BeginWrite( message, 0, message->Length, gcnew AsyncCallback( WriteCallback ), stream );
   }
   catch ( Exception^ authenticationException ) 
   {
      e = authenticationException;
      complete = true;
      return;
   }

}


static void AuthenticateCallback(IAsyncResult ar)
{
    SslStream stream = (SslStream) ar.AsyncState;
    try 
    {
        stream.EndAuthenticateAsClient(ar);
        Console.WriteLine("Authentication succeeded.");
        Console.WriteLine("Cipher: {0} strength {1}", stream.CipherAlgorithm, 
            stream.CipherStrength);
        Console.WriteLine("Hash: {0} strength {1}", 
            stream.HashAlgorithm, stream.HashStrength);
        Console.WriteLine("Key exchange: {0} strength {1}", 
            stream.KeyExchangeAlgorithm, stream.KeyExchangeStrength);
        Console.WriteLine("Protocol: {0}", stream.SslProtocol);
        // Encode a test message into a byte array.
        // Signal the end of the message using the "<EOF>".
        byte[] message = Encoding.UTF8.GetBytes("Hello from the client.<EOF>");
        // Asynchronously send a message to the server.
        stream.BeginWrite(message, 0, message.Length, 
            new AsyncCallback(WriteCallback),
            stream);
    }
    catch (Exception authenticationException)
    {
        e = authenticationException;
