using ICSharpCode.SharpZipLib.Zip; public static void BatchDownFile(List<string> urlList)        {            /*刪除之前的臨時檔案*/            string path = Path.Combine(privateDiskBasePath,"tempZip");            DirectoryInfo dirInfo = new DirectoryInfo(path);            if (dirInfo.Exists)            {                dirInfo.Delete(true);            }            dirInfo.Create();            string fileName = Path.Combine(path, "打包檔案.zip");            using (ZipFile zip = ZipFile.Create(fileName))            {                zip.BeginUpdate();                zip.SetComment("壓縮包");                foreach (var item in urlList)                {                    if (File.Exists(item))//判斷是檔案還是檔案夾                    {                        byte[] buffer = null;                        try                        {                            buffer = File.ReadAllBytes(item);                        }                        catch                        {                        }                        if (buffer != null && buffer.Length > 0)                        {                            StreamDataSource dataSource = new StreamDataSource(buffer);                            string[] fileNameSplit = item.Split(‘\\‘);                            zip.Add(dataSource, fileNameSplit[fileNameSplit.Length - 1]);                        }                    }                }                zip.CommitUpdate();            }            DownFile("打包檔案.zip", fileName);        }
