What is a Boolean C#?

Boolean in C#: Making Sense of True and False

Okay, let’s talk about Boolean in C#. It’s one of those fundamental things you just have to get your head around when you’re coding in C#. Simply put, a Boolean represents a logical value: true or false. Think of it as a light switch – it’s either on (true) or off (false). That’s it.

Now, you might be wondering, “Why is it called ‘Boolean’?” Well, it’s named after George Boole, a mathematician who basically invented Boolean algebra. This algebra is all about logic, and that’s precisely what Boolean values are used for in programming: making decisions. In C#, you’ll usually see it written as bool, which is just a shorter way of saying System.Boolean. Don’t let the two names confuse you; they’re the same thing. I usually stick with bool because, well, it’s quicker to type!

So, how do you actually use these bool things? It’s pretty simple. You declare a variable of type bool and assign it either true or false. Like this:
