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

问题:

As per subject...

回答1:

\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'.

回答3:

"\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.

回答4:

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

回答5:

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).

回答6:

Use Environment.NewLine and don't care.

回答7:

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

回答8:

They are just \r\n and \n are variants.

\r\n is used in windows

\n is used in mac and linux

回答9:

\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.
