SharpZipLib：从.tar文件内部解压缩.gz吗？

        using (FileStream _fsIn = new FileStream(@\"F:\\data\\abc.tar\", FileMode.Open, FileAccess.Read))
        {
            using (TarInputStream _tarIn = new TarInputStream(_fsIn))
            {
                TarEntry _tarEntry;

                while ((_tarEntry = _tarIn.GetNextEntry()) != null)
                {
                    string _archiveName = _tarEntry.Name;

                    using (FileStream _outStr = new FileStream(@\"F:\\data\\\" + _archiveName, FileMode.Create))
                    {
                        _tarIn.CopyEntryContents(_outStr);
                    }
                }
            }
        }
