Take a look at DotNetZip (@AFract supplied a new link to GitHub in the comments) It has got pretty geat documentation and it also allow you to load the dll at runtime as an embeded file.

My condolences, reading the wikipedia description gives me the very strong impression that you need to do a fair amount of guess + check work: Hunt backwards from the end for the 0x06054b50 end-of-directory tag, look forward 16 bytes to find the offset for the start-of-directory tag 0x02014b50, and hope that is it. You could … Read more
I’m leery of aperkins solution (since deleted), but I know why it worked. The line (which has since been corrected in his answer) zipOut.setLevel(ZipOutputStream.STORED); // accidentally right was using the static value ZipOutputStream.STORED, which coincidentally equals 0. So what that line is doing is setting the level used by the default DEFLATED method to zero … Read more
figured: it’s entirely possible, the call to ZipInputStream.getNextEntry() positions the InputStream at the start of the entry and therefore supplying the ZipInputStream is the equivalent of supplying a ZipEntry‘s InputStream. the ZipInputStream is smart enough to handle the entry’s EOF downstream, or so it seems. p.
You have to use namelist() and extract(). Sample considering directories import zipfile import os.path import os zfile = zipfile.ZipFile(“test.zip”) for name in zfile.namelist(): (dirname, filename) = os.path.split(name) print “Decompressing ” + filename + ” on ” + dirname if not os.path.exists(dirname): os.makedirs(dirname) zfile.extract(name, dirname)
Since you are in .NET 4.5, you can use the ZipArchive (System.IO.Compression) class to achieve this. Here is the MSDN documentation: (MSDN). Here is their example, it just writes text, but you could read in a .csv file and write it out to your new file. To just copy the file in, you would use … Read more
See ZipFile Class on MSDN. It shows the required framework version is 4.5. Once the framework version is fixed check you have added a reference to the System.IO.Compression.FileSystem.dll assembly and added a using System.IO.Compression directive to your class.
Maybe Groovy doesn’t have ‘native’ support for zip files, but it is still pretty trivial to work with them. I’m working with zip files and the following is some of the logic I’m using: def zipFile = new java.util.zip.ZipFile(new File(‘some.zip’)) zipFile.entries().each { println zipFile.getInputStream(it).text } You can add additional logic using a findAll method: def … Read more
