How many bytes is \n\r?

Question

I have a .net app that is trying to ftp a file and we're ending up with 1 extra byte per line. My Line Separatro is Environment.NewLine which I beleive transaltes into \n\r. How many bytes is that?

Answer 1

\n\r is 2 bytes.

Answer 2

Two bytes. One for \n and one for \r.

Answer 3

It's 2 bytes, but it should be \r\n not \n\r on windows OSs

Answer 4

It depends on the encoding. In 8-bit encodings as well as UTF-8 it's 2 bytes. In UCS-2 or UTF-16 it's 4 bytes. In UCS-4 or UTF-32 it's 8 bytes.

But the problem is that you're probably FTPing in ASCII mode instead of IMAGE mode.

Answer 5

In ASCII encoding, \n is the Newline character (0x10), \r is the Carriage Return character (0x13).

As Jack has said already, the correct sequence is CR-LF, not vice versa.

FTP is probably adding LF characters to your stream if they are placed incorrectly and you are transmitting the file as Text.

Answer 6

FTP software usually offer a binary and a text transfer mode. In text mode newline translation occurs during the transfer. This might be valid information, depending on what your problem is and why you asked the question.

Answer 7

To answer the implied question:

To use binary-transfer rather than ascii-transfer in C#, use

FtpWebRequest reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://example.com"));
reqFTP.UseBinary = true;
