WinSCP .NET Assembly

First, you need to download and install the assembly.

1. Create an instance of WinSCP.SessionOptions class and fill in all necessary information to allow an automatic connection and authentication of your session.
2. Create an instance of WinSCP.Session class. Optionally you can hook handlers of some events of the class.
3. 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, e.g.,

• Session.GetFiles to download files,
• Session.PutFiles to upload files or
• Session.SynchronizeDirectories to synchronize directories.
