download and decompress a zip file in windows phone 8 application

Question

I am working on a windows phone 8 application (phonegap) which downloads a zip file from my server location, I want to unzip this file in my application at runtime to use the files in the archive.

You can use 3rd party libraries in order to decompress and extract ZIP files in WP7/WP8. The most common one is #ZipLib which you can download the WP7 port from @ http://slsharpziplib.codeplex.com/

My personal favourite library is DotNetZip which is a superset of #ZipLib and much more stable IMO. Here's a quick code sample:

  private void MyExtract()
  {
      string zipToUnpack = "C1P3SML.zip";
      string unpackDirectory = "Extracted Files";
      using (ZipFile zip1 = ZipFile.Read(zipToUnpack))
      {
          // here, we extract every entry, but we could extract conditionally
          // based on entry name, size, date, checkbox status, etc.  
          foreach (ZipEntry e in zip1)
          {
            e.Extract(unpackDirectory, ExtractExistingFileAction.OverwriteSilently);
          }
       }
