The @ symbol allows you to use reserved word. For example:

C#

int @class = 15;

The above works, when the below wouldn't:

C#

int class = 15;

The prefix "@" enables the use of keywords as identifiers[^], which is useful when interfacing with other programming languages. The character @ is not actually part of the identifier, so the identifier might be seen in other languages as a normal identifier, without the prefix. An identifier with an @ prefix is called a verbatim identifier.
