What are the logical operators in C#?

Logical operators are used with Boolean values. The following three logical operators are available in C#.

Let us see an example that shows how to work with logical operators in C#. Here condition is checked for Logical AND operator.

if (a && b) {
   Console.WriteLine("Line 1 - Condition is true");
}

In the same way, let us see how to work with other logical operators in C#.

Example

 Live Demo

using System;

namespace Demo {
   class Program {
      static void Main(string[] args) {
         bool a = true;
         bool b = true;

         if (a && b) {
            Console.WriteLine("Line 1 - Condition is true");
         }
   
         if (a || b) {
            Console.WriteLine("Line 2 - Condition is true");
         }

         a = false;
         b = true;

         if (a && b) {
            Console.WriteLine("Line 3 - Condition is true");
         } else {
            Console.WriteLine("Line 3 - Condition is not true");
         }

         if (!(a && b)) {
            Console.WriteLine("Line 4 - Condition is true");
         }
         Console.ReadLine();
      }
   }
}

Output

Line 1 - Condition is true
Line 2 - Condition is true
Line 3 - Condition is not true
Line 4 - Condition is true
