Reserved Key Words of C# Programming Language tutorials

  • At its foundation, a computer language is defined by its keywords because they determine the features built into the language.

  • C# defines two general types of keywords: reserved and contextual.

  • The reserved keywords cannot be used as names for variables, classes, or methods.

  • They can be used only as keywords. This is why they are called reserved.

  • The terms reserved words or reserved identifiers are also sometimes used.

  • There are currently 79 reserved keywords defined by version 4.0 of the C# language.

  • You cannot use reserved keywords as a indetifier.

  • C# 4.0 defines 25 contextual keywords that have a special meaning in certain contexts.

  • In those contexts, they act as keywords.

  • Outside those contexts, they can be used as names for other program elements, such as variable names.

  • Thus, they are not technically reserved.

  • Below chart shows the reserved keywords of C#:
