            GZipStream compressionStream = new GZipStream(fileStream, CompressionMode.Compress);
            StreamWriter sw = new StreamWriter(compressionStream);

            //遍历每个像素点
            for (int x=0;x<path.Length;x++)
            {
                //Console.WriteLine(path[x]);
                Bitmap bitmap = new Bitmap(path[x]);

                for (int i = 0; i < bitmap.Height; i++)

                        if (color.R > 200)
                        {
                            //Console.Write("1");
                            sw.Write(" ");
                        }

                            sw.Write("#");
                        }
                    }
                    //Console.WriteLine();
                    sw.WriteLine();
                    Console.Clear();
                    Console.WriteLine("{0} of {1} completed! ",x,path.Length);
                }
                bitmap.Dispose();

--------------------编程问答-------------------- 各位大神,我已经解决拉, 谢谢. --------------------编程问答-------------------- 先找个高效的压缩软件，一定要绿色的，例如rar.exe，就一个exe足够。然后复制到项目中，用Process外部调用这个压缩软件进行压缩，给定的参数看该软件说明，只要命令行下输入程序名+ /?即可看到参数说明。
.NET虽然自带压缩类，但是算法很低级，效率差，毕竟高效的算法是要收费的，微软不会免费提供。 --------------------编程问答-------------------- ...怎么看，都像.....
