I'm getting the following exception: 

 

System.ArgumentNullException was unhandled

  Message="Value cannot be null.\r\nParameter name: handler"

  Source="Xceed.Zip"

  ParamName="handler"

  StackTrace:

       at Xceed.Zip.ZipHandler.RemoveZipHandler(ZipHandler handler)

       at Xceed.Zip.ZippedFolder.Finalize()

  InnerException: 

 

 

This exception happens at some later time in execution after I try to create a ZipFolder() and I pass in an invalid zip from a MemoryFile.

 

I am using Xceed 2.0.116.0.  I've seen some forum entries that say you need to upgrade to version 3.2.  I tried using the latest version I could find on your website... 4.1.9616.13400... by copying those DLLs into the bin directory for my application.  I still get an error.  However, I'm not sure if those are really being used since I still have the 2.0.116 in my GAC.  I need to keep those there for other applications that are very dependent on that version.

 

Is there any way to handle this error, without having to upgrade to a newer Xceed DLL?
