Hi,

I am trying to upload a large xml file (around 500 MB) on ftp location,but i

am getting this error---

it works fine upto 250 MB file

The underlying connection was closed: An unexpected error occurred on a

receive.

i am getting the error on this line:-
" Stream strm = ftpRequest.GetR equestStream(); "

i am using the following code:-

               string upd_file = "ftp://" + FTPHost + "/" + FTPFolder + "/" + 

"JJH.xml";
                FtpWebRequest ftpRequest;
                FtpWebResponse ftpResponse;

                 FileInfo fileInf = new FileInfo(file_name);
                    //Settings required to establish a connection with the 

server
                    ftpRequest = (FtpWebRequest)FtpWebRequest.Create(new 

Uri(upd_file));
                    ftpRequest.Method = WebRequestMethods.Ftp.UploadFile;
                    ftpRequest.Proxy = null;
                    ftpRequest.UseBinary = true;
                    ftpRequest.UsePassive = true;
                    ftpRequest.Credentials = new NetworkCredential(username, 

password);
                    ftpRequest.Timeout = int.MaxValue;
                    ftpRequest.ReadWriteTimeout = int.MaxValue;
                    ftpRequest.KeepAlive = false;
                    ftpRequest.ContentLength = fileInf.Length;
                   

                      // The buffer size is set to 2kb
                      int buffLength = 100000;
                      byte[] buff = new byte[buffLength];
                      int contentLen;

                    // Opens a file stream (System.IO.FileStream) to read  

the file to be uploaded
                    FileStream fs = fileInf.OpenRead();

                    // Stream to which the file to be upload is written
                    Stream strm = ftpRequest.GetRequestStream();

                    // Read from the file stream 2kb at a time
                    contentLen = fs.Read(buff, 0, buffLength);

                    // Till Stream content ends
                    while (contentLen != 0)
                    {
                        // Write Content from the file stream to the 
                        // FTP Upload Stream
                        strm.Write(buff, 0, contentLen);
                        contentLen = fs.Read(buff, 0, buffLength);
                    }

                    // Close the file stream and the Request Stream
                    strm.Close();
                    fs.Close();
