What is variable scope in C# methods?

What is variable scope in C# methods?

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

Can you explain the difference between local and global variables?

Local variables are declared within a method and can only be accessed there, while global variables are accessible throughout the entire class.

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

If you try to access a local variable outside its method, you'll get a compile-time error because the variable is out of scope.

Are there any best practices for using variable scope?

Yes, it's best to limit the scope of variables to the smallest possible context to avoid unintended side effects and improve code readability.
