                                    byte[] buff = new byte[Convert.ToInt64(sReader.Length)];
                                    sReader.Read(buff, 0, (int)sReader.Length);
                                    entry.DateTime = fi.LastWriteTime;
                                    entry.Size = sReader.Length;
                                    sReader.Close();
                                    ZipOutputStream zipOut = new ZipOutputStream(File.Create(sPath + fi.Name + ".zip"));
                                    zipOut.PutNextEntry(entry);
                                    zipOut.Write(buff, 0, buff.Length);
                                    zipOut.Finish();
                                    zipOut.Close();
