WinSCP .NET Assembly

First, you need to create an instance of WinSCP.SessionOptions class and fill in all necessary information to allow an automatic connection and authentication of your session.

Then you create an instance of WinSCP.Session class. Optionally you hook handlers of some events of the class. Then you open the session using Session.Open method, passing instance of your WinSCP.SessionOptions.

Once the session is opened, you can use any of the WinSCP.Session methods to manipulate remote files. For example use Session.GetFiles to download files, Session.PutFiles to upload files or Session.SynchronizeDirectories to synchronize directories.
