when to use @ in c#?

Question

I use @ symbol with local path only, but when do I use @ exactly?

Answer 1

AFAIK, You can use @ at any place where you don't want to let the default meaning of the thing persist. For example, @class will make class an identifier. @bool will make bool an identifier instead of a keyword.

You know the usage of @ before strings. It is used to indicate that take all the text of the string literally and don't treat any character in the string specially.

Edit: An yes, another thing to this is that @Keyword is compiled into a Keyword in IL.
