推荐一款很好用的dotnet开源压缩文件操作库

　　压缩和解压缩是一个比较常见的功能需求。 SharpCompress   是一款用  C#   语言编写的开源压缩文件操作库，支持  rar  、 zip  , tar  等文件操作。 压缩
　　创建并保存至指定文件。 using (var archive = ZipArchive.Create()) {     // 从指定目录中添加文件     archive.AddAllFromDirectory(＂D:temp＂);     archive.SaveTo(＂C:temp.zip＂, CompressionType.Deflate); }
　　创建并保存至  Stream  。 var memoryStream = new MemoryStream(); using (var archive = ZipArchive.Create()) {     /// 从指定目录中添加文件     archive.AddAllFromDirectory(＂D:temp＂);      var options = new WriterOptions(CompressionType.Deflate){ LeaveStreamOpen = true});     archive.SaveTo(memoryStream, options); }
　　.tar.gz  文件 using (Stream stream = File.OpenWrite(＂d:1.tar.gz＂)) using (var writer = WriterFactory.Open(stream, ArchiveType.Tar, CompressionType.BZip2)) {     writer.WriteAll(＂D:temp＂, ＂*＂, SearchOption.AllDirectories); }解压缩/// 解压缩所有文件至指定目录 using (var archive = RarArchive.Open(＂Test.rar＂)) {     foreach (var entry in archive.Entries.Where(entry => !entry.IsDirectory))     {         entry.WriteToDirectory(＂D:temp＂, new ExtractionOptions()         {             ExtractFullPath = true,             Overwrite = true         });     } }
　　使用  ReaderFactory   自动检测压缩格式。 using (var stream = File.OpenRead(＂Tar.tar.bz2＂)) using (var reader = ReaderFactory.Open(stream)) {     while (reader.MoveToNextEntry())     {         if (!reader.Entry.IsDirectory)         {             Console.WriteLine(reader.Entry.Key);             reader.WriteEntryToDirectory(@＂C:	emp＂, new ExtractionOptions()             {                 ExtractFullPath = true,                 Overwrite = true             });         }     } }
　　带密码 using (var archive = ArchiveFactory.Open(＂d:1.zip＂, new ReaderOptions { Password = ＂123456＂ })) {     foreach (var entry in archive.Entries)     {         if (!entry.IsDirectory)         {             var options = new ExtractionOptions { ExtractFullPath = true, Overwrite = true };             entry.WriteToDirectory(＂d:temp＂, options);         }     } }
