enter code hereI am having an issue putting my file on a remote FTP server.

I am using WinSCP .NET assembly with C#.

I am able to connect to the FTP server but when I try to use session.PutFile(local,remote) it jumps down to transferResult.Check() with an error:

{WinSCP.SessionRemoteException: Error transferring file 'C:\testfile.txt. ---> WinSCP.SessionRemoteException: Copying files to remote side failed. Could not change to "/ftp:/"; 'ftp:' not found.

Please find my code below.

private static void transferWinSCP()
{
    string userName = myUsername;
    string password = myPassword;
    string path = ftp://hostname.com/f/fofd671e-0eee-4c23-932d-4ba32c938c8f;
    string logPath = ConfigurationManager.AppSettings["LogPath"];**
    try
    {
        SessionOptions sessionOptions = new SessionOptions
        {
            Protocol = Protocol.Ftp,
            HostName = "hostname.com",
            PortNumber = 990,
            UserName = userName,
            Password = password,
            FtpSecure = FtpSecure.Implicit,
            FtpMode = FtpMode.Passive,
            TlsHostCertificateFingerprint = "xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx"
        };

        using (Session session = new Session())
        {

            session.SessionLogPath = logPath;

            //connect
            session.Open(sessionOptions);

            //upload
            TransferOptions transferOptions = new TransferOptions {TransferMode = TransferMode.Binary};

            TransferOperationResult transferResult = session.PutFiles(@"C:\testfile.txt",url, false,
                    transferOptions);
            transferResult.Check(); //ftp error

            foreach (TransferEventArgs transfer in transferResult.Transfers)
            {
                Console.Write("upload of {0} succeeded", transfer.FileName);
            }
        }
    }
    catch (Exception ex)
    {
        Console.Write("error {0}", ex);
    }
}

Here is my log file:

The remotePath argument of the Session.PutFiles method is:

Full path to upload the file to. When uploading multiple files, the filename in the path should be replaced with operation mask or omitted (path ends with slash).

You are not passing in a path, but a URL. What for? You already specified your hostname and protocol in the SessionOptions.

Use a path only.

Also as the path is a target folder name (not a target filename), it has to end with a slash (or with a filename).

string path = "/f/fofd671e-0eee-4c23-932d-4ba32c938c8f/";
...
session.PutFiles(@"C:\testfile.txt", path, false, transferOptions);

See the official example for uploading files with WinSCP .NET assembly.
