Hello:
I found very much easier to use Ionic Zip library, also free and opensource.
http://dotnetzip.codeplex.com/

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);
          }
       }
    }

private void CreateZipFile(){
     using (ZipFile zip = new ZipFile())
  {
    zip.AddFile("ReadMe.txt");
    zip.AddFile("7440-N49th.png");
    zip.AddFile("2008_Annual_Report.pdf");        
    zip.Save("Archive.zip");
  }

}
