Difference between "\n" and Environment.NewLine
提问by Prerak K
What is the difference between two, if any (with respect to .Net)?
两者之间有什么区别（如果有的话）（关于 .Net）？

Depends on the platform. On Windows it is actually "\r\n".
取决于平台。在 Windows 上，它实际上是“\r\n”。
From MSDN:
来自 MSDN：
A string containing "\r\n" for non-Unix platforms, or a string containing "\n" for Unix platforms.
包含“\r\n”的字符串用于非 Unix 平台，或包含“\n”的字符串用于 Unix 平台。

Environment.NewLine will give "\r\n" when run on Windows. If you are generating strings for Unix based environments, you don't want the "\r".
Environment.NewLine 在 Windows 上运行时会给出 "\r\n"。如果您要为基于 Unix 的环境生成字符串，则不需要“\r”。

As others have mentioned, Environment.NewLinereturns a platform-specific string for beginning a new line, which should be:
正如其他人所提到的，Environment.NewLine返回一个用于开始新行的特定于平台的字符串，它应该是：
"\r\n"(\u000D\u000A) for Windows"\n"(\u000A) for Unix"\r"(\u000D) for Mac (if such implementation existed)
"\r\n"(\u000D\u000A) 用于 Windows"\n"(\u000A) 用于 Unix"\r"(\u000D) for Mac（如果存在这样的实现）
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.
请注意，写入控制台时，Environment.NewLine 并不是绝对必要的。"\n"如有必要，控制台流将转换为适当的换行序列。

You might get into trouble when you try to display multi-line message separated with "\r\n".
当您尝试显示以“\r\n”分隔的多行消息时，您可能会遇到麻烦。
It is always a good practice to do things in a standard way, and use Environment.NewLine
以标准方式做事并使用 Environment.NewLine 始终是一个好习惯

Exact implementation of Environment.NewLinefrom the source code:
Environment.NewLine从源代码的确切实现：
The implementation in .NET 4.6.1:
.NET 4.6.1 中的实现：
/*===================================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";
}
}
The implementation in .NET Core:
.NET Core 中的实现：
/*===================================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
}
}
