jQuery Uploadify Plugin: Upload to FTP Folder in ASP.Net

1. Once file is fully uploaded

2. That's the Request Handler that has all the Form fields i.e. INPUT FIELDS Data

I am trying to adjust the upload.ashx in such a way that it stores the files to an ftp location.  I am getting it to work if the user selects a single file, however if the user selects multiple files it only up loads the last file.

the code below is called in the process request function

 HttpPostedFile postedFile = context.Request.Files["Filedata"];
                            BinaryReader b = new BinaryReader(postedFile.InputStream);
                            byte[] buffer = b.ReadBytes(postedFile.ContentLength);
                          
                            if (ftconn.upload(value, buffer) == true)
                            {
                                b.Close();
                                context.Response.StatusCode = 200;
                            }
                            else {
                                context.Response.StatusCode = 500;
                            }

the ftp upload function 

        public bool upload(string remoteFile, byte[] localFilebytes)
        {
            bool statval = true;
            try
            {
                /* Create an FTP Request
              */

                FtpWebRequest ftpRequest = (FtpWebRequest)FtpWebRequest.Create(@_url.Trim() + remoteFile.Trim());

                /* Log in to the FTP Server with the User Name and Password Provided */
                ftpRequest.Credentials = new NetworkCredential(_username, _password);
                ftpRequest.UseBinary = true;
                ftpRequest.Proxy = null;
                ftpRequest.KeepAlive = true;
                /* Specify the Type of FTP Request */

                ftpRequest.Method = WebRequestMethods.Ftp.UploadFile;
                /* Establish Return Communication with the FTP Server */
                Stream ftpStream = ftpRequest.GetRequestStream();

                /* Open a File Stream to Read the File for Upload */
              //  FileStream localFileStream = new FileStream(localFile.Trim(), FileMode.OpenOrCreate);
                /* Buffer for the Downloaded Data */
               // byte[] byteBuffer = localFilebytes.Length;
                // byte[] byteBuffer = File.ReadAllBytes(localFile);

                int bytesSent = localFilebytes.Length;


                /* Upload the File by Sending the Buffered Data Until the Transfer is Complete */
                try
                {
                    //while (bytesSent != 0)
                    //{
                    //    ftpStream.Write(byteBuffer, 0, bytesSent);
                    //    bytesSent = localFileStream.Read(byteBuffer, 0, bufferSize);
                    //    //bytesSent = localFileStream.Read(byteBuffer, 0, bufferSize);
                    //}

                    ftpStream.Write(localFilebytes, 0, bytesSent);
                }
                catch (Exception ex)
                {
                    // Console.WriteLine(ex.ToString());
                    statval = false;
                }
                /* Resource Cleanup */
                //localFileStream.Close();
                ftpStream.Close();
                ftpRequest = null;
            }
            catch (Exception ex)
            {
                // Helper.aid = ex.ToString();
                //Console.WriteLine(ex.ToString()); 
                statval = false;
            }
            return statval;
        }

You cannot with Upload.ashx as it can be called multiple times in any sequence for multiple files.

Hence you might have to write some Windows Service that will do this periodiacally.

Once file is upoloaded same its path in database and also have a flag say FTP = 0

now Windows service will read all files with FTP = 0 and upload it one by one and set FTP = 1 once uploaded
