In c#, Logical Operators are useful to perform the logical operation between two operands like AND, OR, and NOT based on our requirements. The Logical Operators will always work with Boolean expressions (true or false) and return Boolean values.
The operands in logical operators must always contain only Boolean values. Otherwise, Logical Operators will throw an error.
The following table lists the different types of operators available in c# logical operators.
|Operator||Name||Description||Example (a = true, b = false)|
|&&||Logical AND||It returns true if both operands are non-zero.||a && b (false)|
|||||Logical OR||It returns true if any one operand becomes a non-zero.||a || b (true)|
|!||Logical NOT||It will return the reverse of a logical state that means if both operands are non-zero, it will return false.||!(a && b) (true)|
If we use Logical AND, OR operators in c# applications, those will return the result as shown below for different inputs.
If you observe the above table, if any one operand value becomes false, then the logical AND operator will return false. The logical OR operator will return true if any one operand value becomes true.
If we use the Logical NOT operator in our c# applications, it will return the results like as shown below for different inputs.
If you observe the above table, the Logical NOT operator will always return the reverse value of the operand. If the operand value is true, then the Logical NOT operator will return false and vice versa.
Following is the example of using the Logical Operators in c# programming language.
If you observe the above code, we used logical operators (AND, OR, NOT) to perform different operations on defined operands.
When we execute the above c# program, we will get the result as shown below.
This is how we can use logical operators in the c# programming language to perform logical operations on defined operands based on our requirements.
