Save ZipArchive to Stream

Question

I am working on a project where i update a ZipArchive and upload it back to server but I can only upload it using a stream.

public IActionResult DeleteZippedFile(string path)
{
    //read the zip from stream
    var zip = new ZipArchive(DownloadStream(Request.Cookies["OpenedZipPath"]), ZipArchiveMode.Update);

    //make changes
    zip.Entries.Where(x => x.Name == path).ToList()[0].Delete();

    //i want to convert here <------
    ftp.UploadStream(THESTREAMIWANT)

    //and back to the zip
    return RedirectToAction(nameof(OpenZip));
}

How can i save ZipArchive to a stream?

Answer 1

I think this is impossible without a third party library, so i used the Aspose.zip lib. And here is the working code:

public IActionResult DeleteZippedFile(string path)
{
    var zip = new Archive(DownloadStream(Request.Cookies["OpenedZipPath"]));
    zip.DeleteEntry(zip.Entries.FirstOrDefault(x => x.Name == path));
    var ms = new MemoryStream();
    zip.Save(ms);
    ms.Seek(0, SeekOrigin.Begin);
    ftp.UploadStream(ms, Request.Cookies["OpenedZipPath"]);
    return RedirectToAction(nameof(OpenZip));
}
