Winscp uploading failed using C# code

2017-03-23 09:11

Hi All,
Am using Winscp for file moving one machine to another.
its less than 100kb file moving correctly without error.
But more than 100kb file not moving.

/ Setup session options
                SessionOptions sessionOptions = new SessionOptions
                {
                    Protocol = ftpMode.ToUpper().ToString() == "SFTP" ? Protocol.Sftp : Protocol.Scp,
                    HostName = hostname,
                    UserName = username,
                    Password = password,
                    PortNumber = port,
                    GiveUpSecurityAndAcceptAnySshHostKey = true,
                    SshPrivateKeyPath = sshprivetekeypath
                };
               

                using (Session session = new Session())
                {
                    // Connect
                    session.Open(sessionOptions);
                   

                    // Upload files
                    TransferOptions transferOptions = new TransferOptions();
                    transferOptions.FileMask = filemask;
                    transferOptions.TransferMode = TransferMode.Binary;
                    TransferOperationResult transferResult;
                    //transferResult = session.GetFiles("/home/user/*", "d:\\download\\", false, transferOptions);
                    transferResult = session.GetFiles(sourcepath, destinationpath, false, transferOptions);

                    // Throw on any error
                    transferResult.Check();

                   
                }

Re: Winscp uploading failed using C# code

For some reason, your server does not allow WinSCP to create a temporary file with .filepart extension.
https://winscp.net/eng/docs/resume#automatic
I cannot tell why, without more details about your server.

Though as a workaround, just disable the transfer via a temporary file:
transferOptions.ResumeSupport.State = TransferResumeSupportState.Off
