This C# example demonstrates how to write a .zip archive to an in-memory byte array.

            Chilkat.Zip zip = new Chilkat.Zip();
            zip.UnlockComponent("anything for 30-day trial");

            zip.NewZip("not_used.zip");

            zip.AppendOneFileOrDir("fw9.pdf", false);

            // It is obviously easier to simply call WriteZip, but this example shows
            // how WriteToMemory can write the exact image of a zip file into a byte array.
            // You can verify by saving the byte array to a .zip file, and then opening
            // it with a utility program such as WinZip.
            byte[] data = zip.WriteToMemory();

            // Save the byte array to a file.
            FileStream fStream = new FileStream("test2.zip", FileMode.CreateNew);
			BinaryWriter bw = new BinaryWriter(fStream);
			bw.Write(data);
			bw.Close();
			fStream.Close();
