This example is taken from the SDK. And the only file it make is file containing 0kb. Anyone know why?

// Create a new exporter  DataExporter Exporter = new DataExporter();  // Create an output stream string exportFile = Path.GetTempFileName(); Exporter.Stream = new FileStream(exportFile, FileMode.Create, FileAccess.Write, FileShare.None);  // Add pages to the export package, here alla pages below the startpage Exporter.SourceRoots.Add(new ExportSource(PageReference.StartPage,      ExportSource.RecursiveLevelInfinity));  // Export all pages Exporter.Export();  // Close the exporter Exporter.Close();  // Close the out file  Exporter.Stream.Close();
