C# Logical Operators – Effective Use

Logical operators are a central element in programming, especially in C#. They allow you to combine conditions and make logical comparisons. In this guide, you will learn about the different logical operators and understand how they behave in practical applications. Whether you are new to C# or want to refresh your knowledge, this guide provides you with a clear and structured presentation.

Key findings

• Logical operators are crucial for decision-making in programs.
• The negation operator! changes the truth value of a condition.
• The AND operator && returns true only if both operands are true.
• The OR operator || returns true if at least one of the operands is true.

Step-by-step guide

First, you will see how to work with logical operators in C#. We will start with the most important logical operator: negation.

Negation operator!

The negation operator is used to invert the truth value of a variable. Suppose you have two boolean variables: isCold and isSlippery, both set to true. When you apply the negation operator, the truth value is reversed.

This means that the result can only be true if isCold is false. Keep in mind that using the negation operator often requires additional consideration.

AND operator &&

Now let’s look at the AND operator. The AND operator only works if both conditions are true. For example, you can check if it is cold and slippery.

It is important to note that C# evaluates both values when using the single AND operator, whereas the double AND operator && will not test the second condition if the first is already false.

OR operator ||

The OR operator behaves differently than the AND operator. Here, it is sufficient for one of the conditions to be true to achieve a true result.

It should also be noted that C# does not evaluate the second condition when using the double pipe operator || if the first is already true.

Summary – Logical Operators in C

In this guide, you have learned how logical operators work in C#. The negation operator {!}, the AND operator {&&} and the OR operator {||} are foundations on which you can build your decision logic. Use these concepts to improve your programming skills and create complex conditions.
