>> request.ContentLength = stream.Length;

afted allocate stream in buffer, get buffer size

StreamReader sourceStream = new StreamReader((@"c:\imagesTemp\" + filename);
            byte [] buffer1 = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
            sourceStream.Close();
            request.ContentLength = buffer1 .Length;

and get response from server, after upload

FtpWebResponse response = (FtpWebResponse)request.GetResponse();
   
            Console.WriteLine("Upload File Complete, status {0}", response.StatusDescription);
   
            response.Close();

The remote server returned an error: (550) File unavailable (e.g., file not found, no access).

check the upload ftp path for white space between "/"
be sure that you have write access to destination directory
