In C#, you need strings often. Less often, you need a long string, but it still happens. So here’s a nice thing to know. You can split them over multiple lines without need the +
operator and an Environment.NewLine
call.
What you need is a verbatim string literal. Those start with an @
:
@"c:\Docs\Source\a.txt" // rather than "c:\\Docs\\Source\\a.txt"
But the extra nice thing is they can span multiple lines, making them easier to read:
@"Hello
This is text on a new line.
Bye!";
But what if you need to add some variable text to this string? Since C# 6 we can use string interpolation, combined with our verbatim string literal:
var name = "Peter"; $@"Hello {name}, How are you? Bye!";
This works perfectly and gives us very readable code.
