Booleans

Boolean data type represents two logical values true and false. The keyword bool can be used to create a Boolean variable:

main.cs


              12345678910111213141516
            
using System;

namespace ConsoleApp
{
  internal class Program
  {
    static void Main(string[] args)
    {
      bool isOnline = true;
	  Console.WriteLine(isOnline); // Output: True

	  isOnline = false;
	  Console.WriteLine(isOnline); // Output: False
    }
  }
}

Logical values are used especially where we want to execute a piece of code based on a specific condition. We will learn more about conditional statements in the next section.
