ZipFile zipFile = ZipFile.Create("path to zip");
zipFile.BeginUpdate();
zipFile.Add("path to file1", Path.GetFileName("path to file1"));
zipFile.Add("path to file2", Path.GetFileName("path to file2"));
zipFile.CommitUpdate();
zipFile.Close();

using (var zipOutputStream = new ZipOutputStream(File.Create(compressedFilePath)))
