Question

我将大约10GB的大型tar文件上传到ftp服务器。这需要花费大量时间并引发以下错误：无法将数据写入传输连接：远程主机强行关闭现有连接。

我提到了以下内容：

以下是代码：

 FileStream fs = null;
        Stream rs = null;

        try
        {
            string file = args[0].Replace("---"," ");
            string ftpServer = args[1].ToString();

            string uploadFileName = new FileInfo(file).Name;


            string uploadUrl = ftpServer;

            Console.WriteLine("Start Time: {0}", DateTime.Now);
            Console.WriteLine("File Name: {0}",file);

            fs = new FileStream(file, FileMode.Open, FileAccess.Read);

            string ftpUrl = string.Format("{0}/{1}", uploadUrl, uploadFileName);
            FtpWebRequest requestObj = FtpWebRequest.Create(ftpUrl) as FtpWebRequest;
            requestObj.Timeout = -1; // <---- -1 is Infinite

            requestObj.Method = WebRequestMethods.Ftp.UploadFile;

            rs = requestObj.GetRequestStream();

            byte[] buffer = new byte[4096];
            //byte[] buffer = new byte[16000]; // <--- 16k


            int read = 0;
            while ((read = fs.Read(buffer, 0, buffer.Length)) != 0)
            {
                rs.Write(buffer, 0, read);
            }
            rs.Flush();


        }
        catch (Exception ex)
        {
            Console.WriteLine("File upload/transfer Failed.\r\nError Message:\r\n" + ex.Message);
        }
        finally
        {
            if (fs != null)
            {
                fs.Close();
                fs.Dispose();
            }

            if (rs != null)
            {
                rs.Close();
                rs.Dispose();
            }
        }

        Console.WriteLine("End Time: {0}", DateTime.Now);

        Console.WriteLine("Exiting the application.. press any key to continue");
        Console.ReadLine();

更新：我将文件上传到FTP DropBox并且无法访问日志。在尝试通过像FileZilla这样的客户端上传时，速度更快。保管箱的限制为300 GB。是否有可能找到转移率？

由于我是初学者，请解释解决方案以及我的理解。提前致谢。
