Very boiled down:
For FTP you make a TCP Connection to the Server on Port 21.
Use the FTP-Commands to create the data channel. Open another TCP Connection to the returned port and copy the file‘s bytes to the stream.

SFTP uses SSH as transport layer instead of raw TCP Sockets, open the connection per SSH using one of the few SSH Nuget Packages.

Alternatively you could use a NuGet Package for a FTP Client.
