Exact implementation of Environment.NewLine from the source code:
 
  
The implementation in .NET 4.6.1:
 
  
/*===================================NewLine====================================
**Action: A property which returns the appropriate newline string for the given
**        platform.
**Returns: \r\n on Win32.
**Arguments: None.
**Exceptions: None.
==============================================================================*/
public static String NewLine { get { Contract.Ensures(Contract.Result<String>() != null); return "\r\n"; } }
 
  
source
 
  

  
The implementation in .NET Core:
 
  
/*===================================NewLine====================================
**Action: A property which returns the appropriate newline string for the
**        given platform.
**Returns: \r\n on Win32.
**Arguments: None.
**Exceptions: None.
==============================================================================*/
public static String NewLine { get { Contract.Ensures(Contract.Result() != null); #if !PLATFORM_UNIX return "\r\n"; #else return "\n"; #endif // !PLATFORM_UNIX } }
 
  
source (in System.Private.CoreLib)
 
  
public static string NewLine => "\r\n";
 
  
source (in System.Runtime.Extensions)

As others have mentioned, Environment.NewLine returns a platform-specific string for beginning a new line, which should be:
 
   
"\r\n" (\u000D\u000A) for Windows
"\n" (\u000A) for Unix
"\r" (\u000D) for Mac (if such implementation existed)
   
Note that when writing to the console, Environment.NewLine is not strictly necessary. The console stream will translate "\n" to the appropriate new-line sequence, if necessary.
 
   
Just a note, that would be old macs; new (OSX) macs use \n

I found the sequence \newline in a list of escape sequences in the python documentation. I wonder how it is used and for what. At least in my interpreter it seems this is just interpreted as '\n' + 'ewline':
 
>>> print('\newline')
 
ewline
 
解决方案
 
It refers to the actual newline character - the one with character code "16" (0x10) - not the text sequence "newline".
 
So, an example is like:
 
print("a\
 
b")
 
Here, the backslash is succeeded by the newline, inside a string, and what is printed is just "ab" with nothing apart.
 
it differs from \n - in here, the characer following the backslash is n (0x6e), and this sequence is translated to \x10 on parsing the string. On \, the source string contains the \x10 character and that is replaced by an empty string.
 
Maybe the documentation on that page would be more clear if it would read \ instead of just \newline.
