Hi,

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

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

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

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();


Please help me----
