It’s no secret that string interpolation is one of my favorite C# 6 language features because of how well it cleans up that messy composite formatting syntax. A few days ago I was working on some code that contained a verbatim string that included a few of the classic tokens and I wondered if string interpolation would work with verbatim strings as well.
After a quick glance over the MSDN documentation for string interpolation revealed nothing I just decided to give it a shot by adding a dollar sign ($) ahead of the existing at (@) sign and filled the holes with the appropriate expressions. Much to my delight this worked beautifully as shown in the snippet below!
var name = "Dave"; var age = 36; var sentence = $@"Hello! My name is {name}. I'm {age} years old."; Console.WriteLine(sentence);
I later discovered that even though this feature doesn’t seem to be listed in the MSDN documentation (at least anywhere I could find it) that it is explicitly called out in the C# 6 draft specification so hopefully it’ll find its way to the rest of the documentation at some point.
Yeah, this is quite neat. It’s one of the things I like about PowerShell and other scripting languages. I’m glad it came to C#.
