The remote server returned an error: (503) Bad sequence of commands.

While working with FTP some times you gets this error "The remote server returned an error: (503) Bad sequence of commands." to resolve it just do set

_request.KeepAlive = false;

actually by default it keeps your ftp request connection open even your work is done.but when we will set its KeepAlive to false so now it will not give you the error again.
