I used a very similar method when writing my instant messenger client/server. There is some overhead but when weighed out against it’s simplcity its very minimal. If you would like you can download the entire sample project or view the code through this website.

            //CREATE AN FTP REQUEST WITH THE DOMAIN AND CREDENTIALS
            System.Net.FtpWebRequest tmpReq = (System.Net.FtpWebRequest)System.Net.FtpWebRequest.Create("ftp://domain.com/file.txt");
            tmpReq.Credentials = new System.Net.NetworkCredential("userName", "Password");

            //GET THE FTP RESPONSE
            using (System.Net.WebResponse tmpRes = tmpReq.GetResponse())
            {
