var zipPath = Path.Combine(ConfigProvider.InfrastructureSettings.BaseDocumentsPath, fileName + @".zip");

using (FileStream fileStream = new FileStream(zipPath, FileMode.OpenOrCreate, FileAccess.ReadWrite))
{
using (ZipArchive archive = new ZipArchive(fileStream, ZipArchiveMode.Update))
{
ZipArchiveEntry zipArchiveEntry = archive.CreateEntry(fileName + @".xml");
using (StreamWriter streamWriter = new StreamWriter(zipArchiveEntry.Open()))
{
XmlSerializer xmlSerializer = new XmlSerializer(typeof(ImportBase));
xmlSerializer.Serialize(streamWriter, import);
return File(fileStream, "application/zip", fileName);
