In C#, what's the difference between \n
and \r\n
?
C# Solutions
Solution 1 - C#
\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
Solution 2 - C#
> 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'
.

Solution 3 - C#
"\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.
Solution 4 - C#
\n = LF (Line Feed) // Used as a new line character on Unix
\r = CR (Carriage Return) // Used as a new line character on Mac
\r\n = CR + LF // Used as a new line character on Windows
(char)13 = \r = CR
Environment.NewLine = any of the above code based on the operating system
// .NET provides the Environment class which provides many data based on operating systems, so if the application is built on Windows, and you use CR + LF ("\n\r" instead of Environment.NewLine) as the new line character in your strings, and then Microsoft creates a VM for running .NET applications in Unix, then there will be problem. So, you should always use Environment.NewLine when you want a new line character. Now you need not to care about the operating system.
Solution 5 - C#
Basically comes down to Windows standard: \r\n and Unix based systems using: \n
Solution 6 - C#
It's about how the operating system recognizes line ends.
- Windows user \r\n
- Mac user \r
- Linux uses \n
Morale: if you are developing for Windows, stick to \r\n. Or even better, use C# string functions to deal with strings which already consider line endings (WriteLine, and such).
Solution 7 - C#
\n is the line break used by Unix(-like) systems, \r\n is used by windows. This has nothing to do with C#.
Solution 8 - C#
They are just \r\n and \n
are variants.
\r\n
is used in windows
\n
is used in mac and linux
Solution 9 - C#
\r
inserts U+000DCARRIAGE RETURN\n
inserts U+000ALINE FEED
You can insert one, or the other, or both:
\r\n
inserts U+000DU+000A\n\r
inserts U+000AU+000D
If you intention is to indicate "the end of the line", different platforms, and different technologies, expect you to insert different things:
- Windows: U+000DU+000A (i.e.
\r\n
) - HTTP: U+000DU+000A (i.e.
\r\n
) - HTML: U+000A (i.e.
\n
) - Unix: U+000A (i.e.
\n
) - Macintosh: U+000D (i.e.
\r
) - zOS: U+0085 (i.e.
\x85
)
