Hello, I read a file via Stream Reader which is associated with web response from linux server and using Stream Writer to write to a text file. I read a text file and for some reason I read an extra empty line which is not part of the file.Why can it happen? Maybe it has something to do with Linux via Windows ? I did : streamReader.NewLine ="\n" and it didn't help. Why is that? Thanks! > I did : streamReader.NewLine ="\n" and it didn't help. Try "\r\n" or just "\r". Does Stream Reader have a text/binary mode toggle? If you read the file with File.ReadAllText variants do you see the same problem? Is my understanding that operating systems like Linux will used LF (line feed) to represent a new line where operating systems such as Microsoft Windows use CR+LF (Carriage return + Line Feed) to represent a new line. Could this be the cause of your problems? > Hello, > [quoted text clipped - 8 lines] > > *** Sent via Developersdex http://www.developersdex.com *** > I read a file via Stream Reader which is associated with web response > from linux server and using Stream Writer to write to a text file. > I read a text file and for some reason I read an extra empty line which > is not part of the file.Why can it happen?

My guess is that the web server returned: line 1<CR><LF> line 2<CR><LF> ... line n<CR><LF> which turns out to be: line 1 line 2 ... line n (blank line) And I would not really consider it a problem.

[quoted text clipped - 20 lines] > > Arne Or reading between the lines... line 1 (blank line) line 2 (blank line) ... (blank line) line n (blank line) Go for the CR/LF translation problem, got some of the same from VMS, but lacking breaks, so the text is just one line, but looooooooooong... //CY Hello again, My problem is te empty line in the end of te stream. I tried all the options of "/n","/r","/n/r" and nothing helps. Is there any thing I can mplement (except for adding if for ignoring) in order not to read this empty line in the end? Thanks a lot! > My problem is te empty line in the end of te stream.

How sure are you that the empty line doesn't exist in the original file? Many files *do* end with an empty line. What's the binary data at the end of the file?
