Section10.3:Verbatimstringsinstructthecompilertonotuse character escapes

In a normal string, the backslash character is the escape character, which instructs the compiler to look at the next character(s) to determine the actual character in the string. (Full list of character escapes)

In verbatim strings, there are no character escapes (except for “”which is turned into a “). To use a verbatim string, just prepend a @before the starting quotes.
