C# keyword


Visual Studio 2012


Other version

A keyword is a predefined reserved identifier that has special meaning to the compiler. They cannot be used as identifiers in programs unless they have an @ prefix. For example, @if is a valid identifier, but if is not, because if is a keyword.

The keywords listed in the first table in this topic are reserved identifiers in any part of the C# program. The second table in this topic lists the context keywords in C#. Context keywords have a special meaning only in restricted program contexts and can be used as identifiers outside of this context. Often, when new keywords are added to the C# language, they are also added as contextual keywords to avoid breaking programs written in earlier versions of the language.

 Contextual keyword
 

-------------------------------------------------- ------------------------------

 
Context keywords are used to provide specific meaning in code, but it is not a reserved word in C#. Some context keywords (such as partial and where) have special meaning in two or more contexts.
