As long as the FTP server supports the REIN command, you can use the ChangeUser method to change user without disconnecting.
If the FTP server does not support the REIN command, then it is not possible to change the user without disconnecting.
Note : It is not possible to use the SendCommand method to send the USER and PASS commands since these commands return intermediate replies (in the 300s) which are not supported by the SendCommand method.
