FilesUploadResult uploadResponse = await pdfApi.UploadFileAsync(Path.Combine(remoteFolder, documentName), documentName);
Console.WriteLine(uploadResponse.Uploaded[0]);
}
string fdfPath = Path.Combine(remoteFolder, outputFdfName);
// Parse PDF to extract Form fields as FDF in cloud storage.
AsposeResponse response = await pdfApi.PutExportFieldsFromPdfToFdfInStorageAsync(documentName, fdfPath, folder: remoteFolder);
// Checks the response and logs the result.
if (response == null)
Console.WriteLine("ExportFormToFDF(): Unexpected error!");
else if (response.Code < 200 || response.Code > 299)

else
{ // Downloads the updated file for local use.
Console.WriteLine("ExportFormToFDF(): Pdf document '{0}' form fields successfully exported to '{1} file.", documentName, outputFdfName);
Stream stream = pdfApi.DownloadFile(Path.Combine(remoteFolder, outputFdfName));
using var fileStream = File.Create(Path.Combine(localFolder, outputFdfName));
stream.Position = 0;
await stream.CopyToAsync(fileStream);
Console.WriteLine("ExportFormToFDF(): File '{0}' successfully downloaded.", outputFdfName);
}
}
}
