Call the Initialize method to establish a connection to the SFTP server. Initialize sets the Active property to True.
If the Version property was set to the version 3 of the SFTP server before establishing a connection, and the server supports higher versions of the SFTP protocol, then the OnVersionSelect event may be raised. At that user can choose the required version of the SFTP protocol. After the connection was established Initialize sets the ServerVersion and ServerProperties properties.
