//递归方法遍历目录，并统计其中文件的数目
        private int statisticFiles(string directory)
        {
            int statistic=System.IO.Directory.GetFiles(directory).Length;
            string[] directories = System.IO.Directory.GetDirectories(directory);
            //深度遍历子目录
            foreach (string dir in directories)
            {
                if (isDirectory(dir))
                {
                    statistic += statisticFiles(dir);
                }
                else
                {
                    MessageBox.Show("Directory is Inexistence.");
                }
            }
            return statistic;
        }

        private static bool isDirectory(string p)
        {
            return System.IO.Directory.Exists(p);
        }

遍历特定目录及其子目录 （应用实例，压缩指定目录下的所有文件)

这是我迄今所知的最简单的压缩方法。使用了Java类库。

注意：必须在项目中添加对vjslib引用，程序才能通过编译。
