How to delete file recursively using FTPClient?

public static void GetFTPFilesPath(string ftpAddress, string UserName, string Password)

            FtpWebRequest reqFTP = (FtpWebRequest)FtpWebRequest.Create(ftpAddress);

                        //Run this method again as a recursion of the original:
                        parentDirectory += fileName + "/";
                        try
