Upload a File to an SFTP Server

Demonstrates the Chilkat SFtp.UploadFileByName method, which uploads a local file to a remote path in a single call. The first argument is the remote file path and the second is the local file path.

Note: This example uses relative local paths, which are resolved against the application's current working directory. Absolute local paths may also be used. Supply the paths appropriate to your own environment.

Background: This is the simplest way to upload — Chilkat opens the remote file, streams the local file to it, and closes the handle for you, all in one call. The transfer is streamed rather than buffered in memory, so file size is not a limit. Set the PreserveDate property to carry the local file's last-modified time onto the remote file. A remote path beginning with / is absolute; otherwise it is relative to the session's home directory.
