There could be lot of reasons for the issue,

  1. Check file date & time
  2. Size of the file ( Based on server settings)
  3. Try different formats (rar,7z, etc)

Your code

MemoryStream memoryStream = new MemoryStream();
attachment = new System.Net.Mail.Attachment(memoryStream, "test.zip");

passes a Stream, but that Stream is empty (there's nothing in memoryStream).

If you want to use a MemoryStream, you must read the contents of the ZIP file into memory. You can also use a FileStream if the ZIP is already on disk.

If using a MemoryStream, be sure and set its position 0.

memoryStream.Position = 0;

Depending on how you are using SharpZipLib, you may have access to a ZipOutputStream. If you do, I think you could use that.
