How do variables work in methods in C#?

In C#, variables declared within a method are local to that method. They cannot be accessed outside of it.

Can you give me an example of a method with local variables?

Sure! Here's a simple example:

void CalculateSum() {
    int a = 5;
    int b = 10;
    int sum = a + b;
    Console.WriteLine(sum);
}

In this method, a, b, and sum are local variables.

What happens if I try to use those variables outside the method?

If you try to access a, b, or sum outside of CalculateSum, you'll get a compilation error because they are not in scope.

Are there any other types of variables I should know about in C#?

Yes! Besides local variables, you have instance variables, static variables, and parameters. Each has its own scope and lifetime.
