Keywords are reserved words predefined to the C# compiler. These keywords cannot be used as identifiers. However, if you want to use these keywords as identifiers, you may prefix the keyword with the @ character.
In C#, some identifiers have special meaning in context of code, such as get and set are called contextual keywords.
