Question

Is there a way to share one static variable between several different generic classes ?

I have a class

class ClassA <T> : ObservableCollection<T> {

    static int counter;

    //...
}

and a couple of instances of it with different parameter instantiations, like

ClassA<int> a = new ClassA<int>();
ClassA<double> b = new ClassA<double>();
ClassA<float> c = new ClassA<float>();

Is there a way that the instances a, b, and c share the static field counter ?

Any answers and comments are pretty much appreciated 🙂

Answer 1

You could wrap the counter in it’s own singleton class, then reference the counter class from A, B, and C.
