C Sharp (C#) Bool Data Type

The bool datatype represents true/false values. The variable can hold only a true or a false (these two are C# keywords). The bool value is not automatically converted to either 1 or 0. When used bool in an If statement, there is no necessary to check if its true or false using assignment operator ( = ). Have a look at the examples and will be easier to understand.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace ConsoleApplication

{

    class Program

    {

        static void Main(string[] args)

        {

            bool a = true;

            bool b = false;

            Console.WriteLine("The value of a is : {0}", a);

            Console.WriteLine("The value of b is : {0}", b);

            Console.ReadLine();

           

            //using it in an if condition

            if (a)

            {

                Console.WriteLine("If a is true , I will be displayed.");

            }

            else

            {

                Console.WriteLine("If a is false, I will be displayed.");

            }

            if (b)

            {

                Console.WriteLine("If b is true , I will be displayed.");

            }

            else

            {

                Console.WriteLine("If b is false, I will be displayed.");

            }

            Console.ReadLine();

           

        }

    }

}
