Can I have a base class where each derived class has its own copy of a static property?

Question

I have something like the following situation below:

class Base
{
     public static int x;
     public int myMethod()
     {
          x += 5;
          ret         


        

Answer 1

I usually implement subclass specific stuff as an abstract get property

public class Base
{
    // You must pick one option below

    // if you have a default value in the base class
    public virtual int x { get { return 7; /* magic default value */} }

    // if you don't have a default value
    // if you choose this alternative you must also make the Base class abstract
    public abstract int x { get; }
}

public class DerivedA : Base
{
    public override int x { get { return 5; } }
}

public class DerivedB : Base
{
    public override int x { get { return 10; } }
}
