        /// <param name="ftpadss">下载文件的FTP路径</param>

        public static void download(string adss, string ftpadss,string username, string password)
        {
            //FileMode常数确定如何打开或创建文件,指定操作系统应创建新文件。
            //FileMode.Create如果文件已存在，它将被改写
            FileStream outputStream = new FileStream(adss, FileMode.Create);
            FtpWebRequest downRequest = (FtpWebRequest)WebRequest.Create(new Uri(ftpadss));
            downRequest.Credentials = new NetworkCredential(username,password);
            //设置要发送到 FTP 服务器的命令
            downRequest.Method = WebRequestMethods.Ftp.DownloadFile;
            FtpWebResponse response = (FtpWebResponse)downRequest.GetResponse();
            Stream ftpStream = response.GetResponseStream();
            long cl = response.ContentLength;
            int bufferSize = 2048;
            int readCount;
            byte[] buffer = new byte[bufferSize];
            readCount = ftpStream.Read(buffer, 0, bufferSize);
            while (readCount > 0)
            {
                outputStream.Write(buffer, 0, readCount);
                readCount = ftpStream.Read(buffer, 0, bufferSize);
            }
            ftpStream.Close();
            outputStream.Close();
