C#. Запаковать в tar без сжатия

private void AddDirectoryFilesToTar(TarArchive tarArchive, string sourceDirectory, bool recurse)
{
    TarEntry tarEntry = TarEntry.CreateEntryFromFile(sourceDirectory);
    tarArchive.WriteEntry(tarEntry, false);

    string[] filenames = Directory.GetFiles(sourceDirectory);
    foreach (string filename in filenames)
    {
        tarEntry = TarEntry.CreateEntryFromFile(filename);
        tarArchive.WriteEntry(tarEntry, true);
    }
    if (recurse)
    {
        string[] directories = Directory.GetDirectories(sourceDirectory);
        foreach (string directory in directories)
            AddDirectoryFilesToTar(tarArchive, directory, recurse);
    }
}
private void CreateTar(string tgzFilename, string sourceDirectory)
{
    Stream outStream = File.Create(tgzFilename);
    TarArchive tarArchive = TarArchive.CreateOutputTarArchive(outStream);
    tarArchive.RootPath = sourceDirectory.Replace('\\', '/');
    if (tarArchive.RootPath.EndsWith("/"))
        tarArchive.RootPath = tarArchive.RootPath.Remove(tarArchive.RootPath.Length - 1);
    AddDirectoryFilesToTar(tarArchive, sourceDirectory, true);
    tarArchive.Close();
}

НО! Нужно добавить SharpZipLib
