csc -define

The C# compiler option -define allows to define symbols whose existence can be queried at compile time in the source file with #ifdef SYMBOL.

Unlike in C or C++, a symbol cannot be defined to a specific value, that is, macros are impossible.

csc -define:SYMBOL                                 …
csc -define:SYMBOL_ONE;SYMBOL_TWO                  …
csc -define:SYMBOL_ONE;SYMBOL_TWO;SYMBOL_THREE     …
