Upload File to FTP Server

Following is the sample code which uploads a file to FTP Server

        // FileName - the file to be uploaded

        public void UploadFile(string FileName)

        {

            // File will be uploaded as test.doc in ftp server (here it is localhost

            FtpWebRequest ftp = (FtpWebRequest)FtpWebRequest.Create("ftp://localhost/test.doc");

            ftp.Credentials = new NetworkCredential("abcd", "12345");

            ftp.KeepAlive = true;

            ftp.UseBinary = true;

            ftp.UsePassive = true;  // if required

            ftp.Method = WebRequestMethods.Ftp.UploadFile;

            FileStream fst = new FileStream(FileName, FileMode.Open);

            long fileLenght = fst.Length;

            const int bufferLength = 4096;

            byte[] buffer = new byte[bufferLength];

            long count = 0;

            int readBytes = 0;

            Stream rest = ftp.GetRequestStream();

            lblUploadError.Visible = false;

            do

            {

                readBytes = fst.Read(buffer, 0, bufferLength);

                rest.Write(buffer, 0, readBytes);

            }

            while (readBytes != 0);

            fst.Close();

        }
