How to unpack a .zip file in Windows Mobile?

I need to programaticaly unpack a zip archive to folder on Windows Mobile. Is there an easy to use API that I can use directly or should I go with some external library?

From stackoverflow

• If you're using .Net Compact Framework you could go with http://www.icsharpcode.net/OpenSource/SharpZipLib. I believe it supports running on CF.

• You need an external library. There is a zlibce.dll, a native DLL that you can use if C++ is your thang.

  If .NET is your thing then I can recommend DotNetZip, which runs on the .NETCF 2.0, is free, open source, and has good doc, good performance. In the DotNetZip source distrib, there's a CF-Unzipper project that you can view and compile; it demonstrates how to unzip files on the device. Here's a link where you can view the code for the device app.

  This is a snip of the zip-relevant parts of the code. It unzips to a directory that takes its name from the zip file (without the .zip extension).

      private void UnzipSelectedFile()
      {
          string parent = System.IO.Path.GetDirectoryName(_selectedpath);
          string dir = System.IO.Path.Combine(parent,
              System.IO.Path.GetFileNameWithoutExtension(_selectedpath));
          try
          {
              using (var zip1 = new Ionic.Zip.ZipFile(_selectedpath))
              {
                  foreach (var entry in zip1)
                  {
                      entry.Extract(dir, true);
                  }
              }
  
              // re-populate the treeview with the extracted files:
              AddChildren(tvFolders.SelectedNode.Parent);
  
          }
          catch (Exception ex)
          {
              MessageBox.Show("Exception! " + ex);
          }
      }
  

  Here's a link to an online version of the doc for the library.

• Regardless of what language you use you can use Info-ZIP as an external executable.
