Introduction

The preprocessors directives are used to help in conduction compilation . This is give information to the compiler to processes the information before actual compilation starts. All preprocessor directives being # and only white-space characters may appear before a processor directive on a line.

Example

#define PI //define Preprocessor

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace Preproecssor_directives_define_in_c_sharp

{

class Program

{

static void Main(string[] args)

{

#if (PI) //Check Preprocessor conduction

Console.WriteLine("PI is defined in preprocessor\n");

#else

Console.WriteLine("PI is not defined");

#endif

}

}

}
