Note

#define

directives must be listed before anything else in a C# code file.

You are also able to define your own custom preprocessor symbols. For example, assume you

have authored a C# class that should be compiled a bit differently under the Mono distribution of

.NET (see Appendix B). Using #define, you can define a symbol named MONO_BUILD on a file-by-file

basis:

#define DEBUG

#define MONO_BUILD

using System;

namespace PreprocessorDirectives

{

class Program

{

static void Main(string[] args)

{

#if MONO_BUILD

Console.WriteLine("Compiling under Mono!");

#else

Console.WriteLine("Compiling under Microsoft .NET");

To create a project-wide symbol, make use of the Conditional compilation symbols text box

located on the Build tab of your project’s Properties page (see Figure 12-9).
