Not able to find out specific classes in .net so not sure where shall i start from.

FTP as a protocol doesn't provide any means for managing users, neither servers support such mechanisms. If you have your own FTP/FTPS server implementation, you can make use of custom commands (but you will need a client-side protocol implementation that supports custom commands). If you want to manage users of existing FTP servers, then I am afraid you are out of luck.
