What is PreProcessor in .NET and type, where it use?
Submitted by: AdministratorThe pre-processing directives provide the ability to conditionally skip sections of source files, to report error and warning conditions, and to delineate distinct regions of source code. The term "pre-processing directives" is used only for consistency with the C and C++ programming languages. In C#, there is no separate pre-processing step; pre-processing directives are processed as part of the lexical analysis phase.
A preprocessor directive must be the only instruction on a line. Preprocessing directives are lines in your program that start with `#'. Whitespace is allowed before and after the `#'. The `#' is followed by an identifier that is the directive name. For example, `#define' is the directive
Types are:
#if, #else, #elif, #endif, #define, #undef, #warning, #error, #line, #region, #endregion
They are used for:
Conditional compilation
Line control
Error and Warning reporting
For example u can refere the MS site ...
