I'm using System.IO and ZipFile, I was wondering if anyone could give me a snippet of code that extracts files from a .zip archive and puts them into a .jar file, or atleast helps get me started with doing something like that.
JARs are ZIPs just with a different extension, just copy and rename the file.
Jar and zip has exactly same format.
You can add meta-inf to that jar if you want to add some manifest (can be done via JarFile etc)

I zipped one big file into multiple zip files using 7z tool.
It generated xxx.zip.001, xxx.zip.002, xxx.zip.003. so .zip.001 would be parent zip file.
I tried to unzip using SevenZipExtractor.1.0.17. It unzipped the files from the parent file only, but I needed all unzipped.
Actually, when I used WinZip tool, it generate like xxx.zip, xxx.z01, xxx.z02. these all files could be unzipped when I unzipped xxx.zip file.
Is there any library or way for doing this?
I need some help.
I'm trying to zip 3 files, as I you can see in the image
But i only want to zip the two .pdf files (the name is dynamic) and the xml file.

Anyone knows? Thanks in advance.

Have you tried DotNetZip ?
You can use it to zip a folder.
actually i dont have to create folders first. it creates folder automatically when i specify files with folder name. and it works with both the links provided. thanks guys
In my project i have created a file upload.Now it is required that any exe file or exe file in a zip folder having .zip as extension, be prevented from being uploaded.
Can someoe suggest me a solution?
For each of your task, you have to implement separate algorithm for check.
Check extension before upload (see possible duplicate question)
Check that uploaded zip is really an archive (mime type, libmagic, etc)
Check that uploaded archive doesn't contain exe (unzip it, see previous paragraph)
I have a folder structure containing a number of documents, as well as a shortcut link to another file in the folder structure. (essentially the file structure maps like a graph). If I zip up these files in Windows, the shortcut will point to the right file when the archive is uncompressed somewhere else.
Now, I want to be able to do this using the System.IO.Packaging stuff... this requires that I put the each file in a stream to tie it to the zip file. The problem is shortcut files (.lnk) apparently aren't actually files (if you do a file.exist on it, its not there). My normal method of...
System.IO.FileStream(shortcut, System.IO.FileMode.Open)
...will not work. So how would I add a shortcut to a zip package?
A ZipPackage isn't a regular Zip file, but a file meant to be used by new Office XML-based file format (docx, xlsx, etc).
If you want to zip something, you should to use another library, like #ziplib
