This is the main interface class of the WinSCP assembly.
It represents a session and provides methods for manipulating remote files over SFTP, SCP or FTP session.

The class is locked against concurrent accesses from multiple threads. Though you can use several instances of the class in parallel, even from different threads.
Methods from both classes throw
SessionLocalException on error in communication with WinSCP console session.
Methods for atomic operations throw
SessionRemoteException on error originating from WinSCP console session (referred to as “failure” below).
Methods for batch operations returns an instance of descendant of
OperationResultBase class (such as
SynchronizationResult). Such result class stores list of operations performed (e.g.
TransferOperationResult.Uploads), and list of failures (
Every structure representing operation performed may refer (e.g. in
TransferEventArgs.Error) to one of the failures, if the failure can be explicitly associated with the operation. So often the same failure (represented by
SessionRemoteException) will be referenced twice in the results.
But there can be failures that cannot be explicitly associated with any operation represented in results. An example is an error when listing contents of remote directory to determine list of files to downloads. The listing is not represented in the results, so the failure will be included only in a generic list of failures.
If you do not want to check the list of failures after every batch operation method call, you can use method
OperationResultBase.Check to throw the first failure in the list, if any failure occurred:
// Throw, if upload fails session.PutFiles(localPath, remotePath).Check();
Also for all failures the
Session.Failed event is raised.
The batch operation though typically aborts on the first major failure. See example on implementing recursive directory tree download with custom error handling to learn how to continue on errors.
For example how to check and print errors, but continue, see real-life example Search recursively for text in remote directory / Grep files over SFTP/FTP protocol.
