Unity使用SharpCompress压缩与解压缩文件

            size = s.Length;
        }
        return size;
    }

    {

                foreach (var item in files)
                {
                    ws.Write(profix + item.Substring(startPos), File.OpenRead(item), null);
                }
            }
            size = s.Length;
        }
        return size;
    }

    public static bool UncompressMemory(string rootFloder, byte[] bytes)
    {
        using (var ms = new MemoryStream(bytes))
        {
            using (var ar = SharpCompress.Archive.ArchiveFactory.Open(ms))
            {
                foreach (var item in ar.Entries)

                        string file = rootFloder + item.FilePath;
                        string dir = Path.GetDirectoryName(file);
                        if (!Directory.Exists(dir)) Directory.CreateDirectory(dir);

                        using (FileStream fs = new FileStream(file, FileMode.Create))
                        {
                            item.WriteTo(fs);
                        }
                    }
                }
            }
        }
        return true;
    }
