Hallo, i would like to insert/append a file to an archive, for example

Insert(string fileName, string archiveName);

it should insert the file with fileName to archive of archiveName 

some modification would be: 

Insert(ZipEntry entry,  string fileName, string archiveName);

where file should be under the entry placed

how should i open such a ZipOutputStream? 

Any idea?

Thanks

 Hi,

ZipOutputStream doesnt support that kind of operation directly.  ZipFile is more amenable to your task I think.  Have a look at the zf c# sample whic exercises this class.

hth, -jr-

afaik ZipFile gives you no information about compression-progress. there are no events supported, no observers can be injected.

I consider, maybe I could use an descendant of FileStream as parameter in his constructor, which has hooks in their Read/Write methods, and gives back the bytecount which was readed. I see no other possibilities of observing the progress. Any other idea?

Hi,

Yes a code tweak is required.  A parameter in the constructor seems less flexible than being able to set it via a property or perhaps when you commit an update.
