The following code example sends an FTP request to make a new directory on an FTP server and checks the status code returned in the response.
public static bool MakeDirectoryOnServer (Uri serverUri) { // The serverUri should start with the ftp:// scheme. if (serverUri.Scheme != Uri.UriSchemeFtp) { return false; } // Get the object used to communicate with the server. FtpWebRequest request = (FtpWebRequest)WebRequest.Create (serverUri); request.KeepAlive = true; request.Method = WebRequestMethods.Ftp.MakeDirectory; FtpWebResponse response = (FtpWebResponse)request.GetResponse (); Console.WriteLine ("Status: {0}", response.StatusDescription); return true; }
