9.5.6 Region control
The region directives are used to explicitly mark regions of source code.
pp-region::
pp-start-region conditional-sectionopt pp-end-region
C# LANGUAGE SPECIFICATION
68
pp-start-region::
whitespaceopt # whitespaceopt region pp-message
pp-end-region::
whitespaceopt # whitespaceopt endregion pp-message
No semantic meaning is attached to a region; regions are intended for use by
the programmer or by automated
tools to mark a section of source code. The message specified in a #region
or #endregion directive likewise
has no semantic meaning; it merely serves to identify the region. Matching
#region and #endregion directives
may have different pp-messages.
The lexical processing of a region:
#region
...
#endregion
corresponds exactly to the lexical processing of a conditional compilation
directive of the form:
#if true
...
#endif
