Ejemplos

En el ejemplo de código siguiente se recupera el punto de servicio de una solicitud y se establece el número máximo de conexiones en uno.

static bool ListFilesOnServer( Uri^ serverUri )
{
   // The serverUri should start with the ftp:// scheme.
   if ( serverUri->Scheme != Uri::UriSchemeFtp )
   {
      return false;
   }

   // Get the object used to communicate with the server.
   FtpWebRequest^ request = dynamic_cast<FtpWebRequest^>(WebRequest::Create( serverUri ));
   request->Method = WebRequestMethods::Ftp::ListDirectory;

   // Get the ServicePoint object used for this request, and limit it to one connection.
   // In a real-world application you might use the default number of connections (2),
   // or select a value that works best for your application.
   ServicePoint^ sp = request->ServicePoint;
   Console::WriteLine( "ServicePoint connections = {0}.", sp->ConnectionLimit );
   sp->ConnectionLimit = 1;
   FtpWebResponse^ response = dynamic_cast<FtpWebResponse^>(request->GetResponse());

   // The following streams are used to read the data returned from the server.
   Stream^ responseStream = nullptr;
   StreamReader^ readStream = nullptr;
   try
   {
      responseStream = response->GetResponseStream();
      readStream = gcnew StreamReader( responseStream,System::Text::Encoding::UTF8 );
      if ( readStream != nullptr )
      {
         // Display the data received from the server.
         Console::WriteLine( readStream->ReadToEnd() );
      }

      Console::WriteLine( "List status: {0}", response->StatusDescription );
   }
   finally
   {
      if ( readStream != nullptr )
      {
         readStream->Close();
      }

      if ( response != nullptr )
      {
         response->Close();
      }
   }

   return true;
}

public static bool ListFilesOnServer(Uri serverUri)
{
    // The serverUri should start with the ftp:// scheme.
    if (serverUri.Scheme != Uri.UriSchemeFtp)
    {
        return false;
    }
    // Get the object used to communicate with the server.
    FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverUri);
    request.Method = WebRequestMethods.Ftp.ListDirectory;

    // Get the ServicePoint object used for this request, and limit it to one connection.
    // In a real-world application you might use the default number of connections (2),
    // or select a value that works best for your application.

    ServicePoint sp = request.ServicePoint;
    Console.WriteLine("ServicePoint connections = {0}.", sp.ConnectionLimit);
    sp.ConnectionLimit = 1;

    FtpWebResponse response = (FtpWebResponse) request.GetResponse();

    // The following streams are used to read the data returned from the server.
    Stream responseStream = null;
    StreamReader readStream = null;
    try
    {
        responseStream = response.GetResponseStream();
        readStream = new StreamReader(responseStream, System.Text.Encoding.UTF8);

        if (readStream != null)
        {
            // Display the data received from the server.
            Console.WriteLine(readStream.ReadToEnd());
        }
        Console.WriteLine("List status: {0}",response.StatusDescription);
    }
    finally
    {
        if (readStream != null)
        {
            readStream.Close();
        }
        if (response != null)
        {
            response.Close();
        }
    }

    return true;
}

Comentarios

Si no existe ningún ServicePoint objeto, se crea uno para el servidor FTP. Para establecer el número máximo de conexiones que se pueden abrir para un servidor FTP, establezca la ConnectionLimit propiedad de la ServicePoint instancia devuelta por esta propiedad.
