The logical operators provided by C# perform the most commonly used logical 

operations. However, several other operations are defined by the rules for formal logic. These 

other logical operations can be constructed using the logical operators supported by C#. 

Thus, C# supplies a set of logical operators sufficient to construct any other logical operation. 

For example, another logical operation is 

implication.

 Implication is a binary operation in 

which the outcome is false only when the left operand is true and the right operand is false. 

(The implication operation reflects the idea that true cannot imply false.) Thus, the truth 

table for the implication operator is shown here:

The implication operation can be constructed using a combination of the
