C# FTP下载文件遇到错误
本帖最后由 Horane 于 2013-08-09 12:45:19 编辑 代码如下

        public void DownloadFtp(string local, string URI)
        {
            try
            {
                FtpWebRequest reqFTP;
                FileStream outputStream = new FileStream(local, FileMode.Create);
                reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(URI));
                reqFTP.Method = WebRequestMethods.Ftp.DownloadFile;
                reqFTP.UseBinary = true;
                reqFTP.KeepAlive = false;
                reqFTP.Credentials = new NetworkCredential("hj", "hj");
                FtpWebResponse response = (FtpWebResponse)reqFTP.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();
                response.Close();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

Response的时候ContentLength是-1,获得responsestream的时候流对象的Length提示此流不支持查找操作.
我用虚拟机搭的一个测试用的ftp服务器,上传和删除文件都正常,但是下载一直这样,求大神解答. C# ftp 下载

建议你买一张灵符，贴上之后，重启下电脑，估计会好的，不好加我qq
