Connection timed out
Issue: WinSCP intermittently (< 1 in 250 times) unable to connect to required FTP site. Connection failure causes fatal error; execution of C# script stops.
Requirement was for a retry a few seconds later, up to a maximum of three attempts.
Spent numerous hours on forum/website. Knew there was an answer somewhere but couldn't find worked example or sufficient details of how to approach it in C#.
Did resolve issue, so code below is for others who may be searching for similar.

// Set up session options SessionOptions sessionOptions = new SessionOptions { Protocol = Protocol.Sftp, HostName = _hostName, UserName = _userName, Password = _password, SshHostKeyFingerprint = _sshHostKey, }; using (Session session = new Session()) { // Will continuously report progress of synchronization session.FileTransferred += FileTransferred; // Attempt to loop through opening the session three times. int loop = 0; while (loop < 3) { try { // Open session. Break out of loop if successful session.Open(sessionOptions); break; } catch (SessionRemoteException e) { //Increment the loop and wait 5 seconds. If three failed attempts, throw an exception loop++; if (loop >= 3) throw e; Thread.Sleep(5000); } catch (Exception e) { // All other exceptions, pass e up to parent catch throw e; } } }
