Difference between "\n" and Environment.NewLine

Depends on the platform. On Windows it is actually "\r\n".

From MSDN:

A string containing "\r\n" for non-Unix platforms, or a string containing "\n" for Unix platforms.

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.

Environment.NewLine will return the newline character for the corresponding platform in which your code is running

you will find this very useful when you deploy your code in linux on the Mono framework

From the docs ...

A string containing "\r\n" for non-Unix platforms, or a string containing "\n" for Unix platforms.

You might get into trouble when you try to display multi-line message separated with "\r\n".

It is always a good practice to do things in a standard way, and use Environment.NewLine

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".
