Solution

To add a reference, right click on your project and select Add Reference

Then browse and add the file

Then here is basic code that shows you how to add a file to the zip

 using (ZipFile zip = new ZipFile())
 {
     zip.AddFiles(.....);
     zip.Save(....);

 }

Where the dots are in the code sample above, use intellisense and fill out the required parameters.
