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
     
      () != null); return "\r\n"; } }
     

---

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 } }

(in System.Private.CoreLib)

public static string NewLine => "\r\n";

(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
