empty lines

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!

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?

My guess is that the web server returned:

line 1
line 2
....
line n

which turns out to be:

line 1
line 2
....
line n
(blank line)

And I would not really consider it a problem.

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...
