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

Question

As per subject...

Answer 1

\n is the line break used by Unix(-like) systems, \r\n is used by windows. This has nothing to do with C#.

Answer 2

Basically comes down to Windows standard: \r\n and Unix based systems using: \n

http://en.wikipedia.org/wiki/Newline

Answer 3

\n = LF (Line Feed) // Used as a new line character in Unix

\r = CR (Carriage Return) // Used as a new line character in Mac

\r\n = CR + LF // Used as a new line character in 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 in Windows, and you use CR + LF ("\n\r" instead of Environment.NewLine) as new line character in your strings, and then MS 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 operating system.

Answer 4

It's about how operating system recognize 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).

Answer 5

"\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.

Answer 6

\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.
