c# - Why is character being doubled in my @ string?

Question

var phone = @"^+(?:[0-9] ?){6,14}[0-9]$";

phone will then equal ^\+(?:[0-9] ?){6,14}[0-9]$

I thought (and the examples I found seem to show) the @ character meant to leave my string how I have it. Why is it doubling the and how do I stop it?

Answer 1

The visual studio debugger will show it as if it were doubled, since in C# a would precede an escape sequence. Don't worry - your string is unchanged.
