Title Body

Due to some firewall issues, we need to do FTP using "active" mode (i.e. not by initiating a PASV command). Currently, we're using code along the lines of: // Get the object used to communicate with the server. FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://www.contoso.com/test.htm"); request.Method = WebRequestMethods.Ftp.UploadFile; // This example assumes the FTP site uses anonymous logon. request.Credentials = new NetworkCredential ("anonymous","janeDoe@contoso.com"); // Copy the contents of the file to the request stream. StreamReader sourceStream = new StreamReader("testfile.txt"); byte [] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd()); sourceStream.Close(); request.ContentLength = fileContents.Length; Stream requestStream = request.GetRequestStream(); requestStream.Write(fileContents, 0, fileContents.Length); requestStream.Close(); FtpWebResponse response = (FtpWebResponse)request.GetResponse(); response.Close(); But this seems to default to using passive mode; Can we influence this to force it to upload using active mode (in the same way that the command line ftp client does)?
