本文详细解析了.NET Framework中Environment.NewLine属性的实现方式，该属性返回适用于当前平台的新行字符串。在.NET 4.6.1中，对于Win32平台返回' '，而在.NET Core中，对于Win32返回' '，对于Unix平台返回' '。文章还提到了在控制台写入时，Environment.NewLine并非严格必要，因为控制台流会根据需要将' '转换为适当的新行序列。

Answer1

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)

Answer2

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
