Error zipping Xceed Zip InvalidZipStructureException The zip end header signature could not be found in the zip file

Error zipping Xceed Zip InvalidZipStructureException The zip end header signature could not be found in the zip file

Hi there,

 

I get a errors when zipping files on OS X 10.4.11 (Tiger) but it works great on OS X 10.5.6 (Leopard) running on mono 2.2.

I just place the DLL’s in the same folder as the .exe and it works great on Leopard but not on Tiger.

I am using the Xceed Zip for .Net 3.7 component and VS Studio 2005.NET and C# 2.0.

Needless to say this code works on Windows and the latest Mac OS X.

 

Any ideas? Thanks.

 

 

If I use QuickZip it does create the zip file but mono and my application disappears and I get the error:

*****************************************************************************

My code (I also tried “/var/tmp/” folder with the same error):

  Xceed.Zip.QuickZip.Zip(“/test.zip”, true, false, false, “/test.txt”);

 

Error returned:

Xceed.Zip.QuickZipException: An error occurred while adding files to the zip file. —> Xceed.Zip.InvalidZipStructureException: The zip end header signature could not be found in the zip file.

If I don’t use QuickZip it does create the zip file but mono and my application disappears and I get the error:
