How to give an Order to the files included in zip file created with dotnet Zip

Question

I would like to be able to include the file with a given order while creating a zip while using DotNet Zip.

Files don't appear in the sequence they were added to the zip.For now the order appears to be random.

I would like to have the files xyz-Header,xyz-Summary included first and then the rest of the files.

xyz-Header.csv

xyz-Summary.csv

xyz-Male.csv

xyz-Female.csv

xyz and names for other files are programmatically determined but Header and Summary files are always included.

Code Snippet

    private MemoryStream GetZip()
    {
        ZipFile zip = new ZipFile();
        List<string, string> files = getFiles();
        zip.AddEntry("xyz-Header.csv", getHeader(files ));
        zip.AddEntry("xyz-Summary", getSummary(files));

        foreach (var x in files)
        {
            zip.AddEntry("xyz-" + x.Item1 + ".csv", x.Item2);
        }

        MemoryStream memoryStream = new MemoryStream();
        zip.Save(memoryStream);
        memoryStream.position = 0;
        return memoryStream;
    }

I would appreciate any help on this.

There is not reason the files have to be ordered in the zip, you can get the file list and the give it any order you like:

  using (ZipFile zip = ZipFile.Read(NameOfExistingZipFile))
  {
    foreach (ZipEntry e in zip.Order(x => x.FileName))
    {
      // do your styff e.Extract();
    }
  }
