使用 ICSharpCode.SharpZipLib.Zip压缩解压文件
/// <summary> /// 功能:解压zip格式的文件。 /// </summary> /// <param name="zipFilePath">压缩文件路径</param> /// <param name="unZipDir">解压文件存放路径,为空时默认与压缩文件同一级目录下,跟压缩文件同名的文件夹</param> /// <returns>解压是否成功</returns> public static bool UnZip(string zipFilePath, string unZipDir) { try { if (zipFilePath == string.Empty) { throw new Exception("压缩文件不能为空!"); } if (!File.Exists(zipFilePath)) { throw new FileNotFoundException("压缩文件不存在!"); } //解压文件夹为空时默认与压缩文件同一级目录下,跟压缩文件同名的文件夹 if (unZipDir == string.Empty) unZipDir = zipFilePath.Replace(Path.GetFileName(zipFilePath), Path.GetFileNameWithoutExtension(zipFilePath)); if (!unZipDir.EndsWith("/")) unZipDir += "/"; if (!Directory.Exists(unZipDir)) Directory.CreateDirectory(unZipDir); using (var s = new ZipInputStream(File.OpenRead(zipFilePath))) { ZipEntry theEntry; while ((theEntry = s.GetNextEntry()) != null) { string directoryName = Path.GetDirectoryName(theEntry.Name); string fileName = Path.GetFileName(theEntry.Name); if (!string.IsNullOrEmpty(directoryName)) { Directory.CreateDirectory(unZipDir + directoryName); } if (directoryName != null && !directoryName.EndsWith("/")) { } if (fileName != String.Empty) { using (FileStream streamWriter = File.Create(unZipDir + theEntry.Name)) { int size; byte[] data = new byte[2048]; while (true) { size = s.Read(data, 0, data.Length); if (size > 0) { streamWriter.Write(data, 0, size); } else { break; } } } } } } return true; } catch (Exception) { return false; } } /// <summary> /// 压缩所有的文件 /// </summary> /// <param name="filesPath"></param> /// <param name="zipFilePath"></param> public static void CreateZipFile(string filesPath, string zipFilePath) { if (!Directory.Exists(filesPath)) { return; } ZipOutputStream stream = new ZipOutputStream(File.Create(zipFilePath)); stream.SetLevel(0); // 压缩级别 0-9 byte[] buffer = new byte[4096]; //缓冲区大小 string[] filenames = Directory.GetFiles(filesPath, "*.*", SearchOption.AllDirectories); foreach (string file in filenames) { ZipEntry entry = new ZipEntry(file.Replace(filesPath, "")); entry.DateTime = DateTime.Now; stream.PutNextEntry(entry); using (FileStream fs = File.OpenRead(file)) { int sourceBytes; do { sourceBytes = fs.Read(buffer, 0, buffer.Length); stream.Write(buffer, 0, sourceBytes); } while (sourceBytes > 0); } } stream.Finish(); stream.Close(); }
里面是参考网友的,使用比较顺手。
