FTPing a file to UNIX

I'm trying to write a VB application that will FTP a file from windows to UNIX. I'm using the FTPWebRequest class and have been able to pull a file from UNIX to Windows but can't get it to push the file from Windows to UNIX. I think the real isssue is that the file is created using IO.Filestream and I not sure that will work on UNIX. BUT if any one has any suggestions I'm game.

At this point I'm going to start down the path of writting the FTP command to a file that is then executed via a shell function.
