In C#, what's the difference between \n and \r\n?

\n is Unix, \r is Mac, \r\n is Windows.

Sometimes it's giving trouble especially when running code cross platform. You can bypass this by using Environment.NewLine.

Please refer to What is the difference between \r, \n and \r\n ?! for more information. Happy reading

The Difference

There are a few characters which can indicate a new line. The usual ones are these two:

* '\n' or '0x0A' (10 in decimal) -> This character is called "Line Feed" (LF).
* '\r' or '0x0D' (13 in decimal) -> This one is called "Carriage return" (CR).

Different Operating Systems handle newlines in a different way. Here is a short list of the most common ones:

* DOS and Windows

They expect a newline to be the combination of two characters, namely '\r\n' (or 13 followed by 10).

* Unix (and hence Linux as well)

Unix uses a single '\n' to indicate a new line.

* Mac

Macs use a single '\r'.

Taken from Here

"\n" is just a line feed (Unicode U+000A). This is typically the Unix line separator.

"\r\n" is a carriage return (Unicode U+000D) followed by a line feed (Unicode U+000A). This is typically the Windows line separator.
