What is variable scope in C#?

Variable scope in C# refers to the visibility and lifetime of a variable within your code. It determines where a variable can be accessed.

Can you explain the different types of variable scope?

Sure! In C#, there are three main types of variable scope: local, instance, and static. Local variables are accessible only within the method they are declared in, instance variables belong to an instance of a class, and static variables are shared across all instances of a class.

What happens if I try to access a local variable outside its scope?

If you try to access a local variable outside its scope, you'll get a compile-time error indicating that the variable is not defined in that context.

Can you give an example of variable scope in a C# program?

Certainly! Here's a simple example:

class Program {
    static int staticVar = 10; // Static variable

    void Method() {
        int localVar = 5; // Local variable
        Console.WriteLine(localVar); // Accessible here
    }
}

In this example, localVar can only be accessed within Method, while staticVar can be accessed anywhere in the class.
