Is it possible to enter a New Line in a string without Escape Sequences?

I want a String to have a New Line in it, but I cannot use escape sequences because the interface I am sending my string to does not recognize them. As far as I know, C# does not actually store a New Line in the String, but rather it stores the escape sequence, causing the literal contents to be passed, rather than what they actually mean.

My best guess is that I would have to somehow parse the number 10 (the decimal value of a New Line according to the ASCII table) into ASCII. But I'm not sure how to do that, because C# parses numbers directly to String if attempting this:

"hello" + 10 + "world"

Any suggestions?

If you say "hello\nworld", the actual string will contain:

hello
world

There will be an actual new-line character in the string. At no point are the characters \ and n stored in the string.

There are a few ways to get the exact same result, but a simple \n in the string is a common way.

A simple cast should also do the same:

"hello" + (char)10 + "world"

Although likely slightly slower because of string concatenation. I say "likely" because it could probably be optimized away, or an actual example using \n will also result in string concatenation, taking roughly the same amount of time.

Test.

The preferred new line character is Environment.NewLine for its cross-platform capability.
