I've used Ionic ZIP for this in our own projects.

using (ZipFile zip = new ZipFile())
 {
     // add this map file into the "images" directory in the zip archive
     zip.AddFile("c:\\images\\personal\\7440-N49th.png", "images");
     // add the report into a different directory in the archive
     zip.AddFile("c:\\Reports\\2008-Regional-Sales-Report.pdf", "files");
     zip.AddFile("ReadMe.txt");
     zip.Save("MyZipFile.zip");
 }
