CRC check failed on Access mdb

Nov 23, 2011 at 4:22 PM

I'm converting a large app from Classic asp to Net (C#).  Am at program that reads SQL db and writes to an older version (2000 & 2003) of Access.  Resultant mdb file will be downloaded from link on web so of course it needs zipped.  Did this in classic asp via pkzip25.exe.  works great.  attempting to use Ionic zip for Net version; nothing fancy, just zip the mdb file. 

Error Msg: CRC check failed. Expected 5BA3BB69, actual 55F12F6B

1. I have latest version of Ionic zip in bin directory

2. Namespace: using Ionic.Zip;


            using (ZipFile zip = new ZipFile())
                zip.AddFile(@csPath2 + csDBmdb,"");
                zip.Save(@csPath2 + csDBzip);

4. Debug shows correct path and no errors during execution.

Appreciate help.  Thanks. Janis
