Static Variable In Inherited Classes

[Bryan Green]

So I'm working on a project for a C# class I'm taking, where I need to
keep some running totals via static variables. I need three classes
for three different types of objects. The base class and inherited
classes are all identical. I need to refer to the static variables in
each class, and each must maintain its own values for each static
variable.

Now: when I inherit my base classes, the static variables in all my
classes contain the same values. BUT: if I copy and paste the code
from my base class into two new renamed classes (versus using
inheritance), each class maintains its own distinct values in all the
static variables. In other words, Class1.StaticVariable is different
from Class2.StaticVariable, etc.

What I need to do (for this assignment) is to see this behavior using
inheritance instead. But as I stated earlier, when I inherit the base
class, Class1.StaticVariable = Class2.StaticVariable =
Class3.StaticVariable.

And, by the way, these variables values' are being incremented with
each classes contructor (and not a class method).

Thanks in advance for any advice!
