Ftp directory exists

Question

Hello I have been trying to make a directory on a server. I can make the directory but if the directory exists it gives me an error. I have been searching the net for information on how to check if the directory exists. The only thing I could find is that I need to set FtpWebRequest.Method to "NLST" and I don't understand what that means. Got more code doing other things on the local computer but haven't worked with FTP before.
