{
    public class TarCreateFromStream
    {
        public void CreateTar(string outputTarFilename, string sourceDirectory)
        {
            using (FileStream fs = new FileStream(outputTarFilename, FileMode.Create, FileAccess.Write, FileShare.None))
            using (Stream gzipStream = new GZipOutputStream(fs))
            using (TarArchive tarArchive = TarArchive.CreateOutputTarArchive(gzipStream))
            {
                AddDirectoryFilesToTar(tarArchive, sourceDirectory, true);
            }
        }

        private void AddDirectoryFilesToTar(TarArchive tarArchive, string sourceDirectory, bool recurse)
        {
            if (recurse)
            {
                string[] directories = Directory.GetDirectories(sourceDirectory);
                foreach (string directory in directories)
                    AddDirectoryFilesToTar(tarArchive, directory, recurse);
            }


            string[] filenames = Directory.GetFiles(sourceDirectory);
            foreach (string filename in filenames)
            {
                TarEntry tarEntry = TarEntry.CreateEntryFromFile(filename);
                tarArchive.WriteEntry(tarEntry, true);
            }
        }
    }
