C#: Barcode to byte array to valid zip file

Question

I'm scaning a Pdf417 barcode which returns me a byte[] array. The DataString itself is a cryptic value like face to keyboard multiple times and fast. So I'm guessing it could be a zip file which is stored in the barcode. In the zip file there should be a xml file. I had different attempts so far to convert my byte[] array to a valid zip file. In the end I was never able to open said zip file. The barcodes are created by certified software solutions, so the barcode is not the problem for sure. I can't be the only one who has had this problem, right?

Output when reading a barcode with dummy data in it:

Dont pay too much attention to this function, at this stage I'm probably trying too much to get to a solution. This is just one of many test voids of mine.

public void Test(byte[] bytes)
    {
        byte[] zipBytes;

        using (var memoryStream = new MemoryStream())
        {
            using (var zipArchive = new ZipArchive(memoryStream, ZipArchiveMode.Create, leaveOpen: true))
            {
                var zipEntry = zipArchive.CreateEntry("test");
                using (Stream entryStream = zipEntry.Open())
                {
                    entryStream.Write(bytes, 0, bytes.Length);
                }
            }
            zipBytes = memoryStream.ToArray();
        }

        using (var fileStream = new FileStream(@"C:\BarcodeReaderTesting\test.zip", FileMode.OpenOrCreate))
        {
            fileStream.Write(zipBytes, 0, zipBytes.Length);
        }
    }

Any tips on this topic?
