Logical Operators are used to compute the logical operation in a program such as &&, || and !. They are used to evaluate the condition.
The following are the C# Logical Operators. Assume X holds the value 1 and Y holds 0
| Operator | Description | Example |
| && (logical and) | If both the operands are non-zero, then the condition becomes true. | (X && Y) is false |
| || (logical or) | If any of the two operands are non-zero, then the condition becomes true. | (X || Y) is true |
| ! (logical not) | Use to reverses the logical state of its operand. If a condition is true then Logical NOT operator will make false. | !(X && Y) is true |
Example of Logical Operators in C#
using System;
namespace Operators
{
class Logical
{
static void Main(string[] args)
{
bool a = true;
bool b = false;
Console.WriteLine("'!' Operator: {0}", !b);
Console.WriteLine("'||' Operator: {0}", a || b);
Console.WriteLine("'&&' Operator: {0}", a && b);
}
}
}Output:
'!' Operator: True
'||' Operator: True
'&&' Operator: False
