C# language contains some reserved words which are pre-defined and have a special meaning for the compiler. These are called the C# keywords.
Keywords cannot be used as an identifier of a variable, interface, class, namespace, etc. There are several categories where keywords will be distributed. Some of them are the Data type related keywords like int, byte, char, string, etc.
Modifier keywords like abstract, const, extern, override, partial, Readonly, etc.
Access modifier keywords like private, public, protected, internal, etc. Please refer to the C# tutorial.
