C# Language Specification

Pragma directives

The #pragma preprocessing directive is used to specify optional contextual information to the compiler. The information supplied in a #pragma directive will never change program semantics.

pp-pragma:
whitespace_opt # whitespace_opt pragma whitespace pragma-body pp-new-line

pragma-body:
pragma-warning-body

C# provides #pragma directives to control compiler warnings. Future versions of the language may include additional #pragma directives. To ensure interoperability with other C# compilers, the Microsoft C# compiler does not issue compilation errors for unknown #pragma directives; such directives do however generate warnings.
