Is it possible to use "Passive Mode" with FtpWebRequest

Question

We have a process in place to upload a file nightly to a partner FTP site. They now require a passive connection and our uploads now fail. Is it possible for the .NET 4 FtpWebRequest to implement a passive connection instead of an active one? If so, can someone please provide an example?

Set the UsePassive property to true on the FtpWebRequest.

Just to add something to an old post - The FtpWebRequest.UsePassive property is True by default, so all requests should use passive already.
