Question

How to call x of class a from object of class b without marking x of class a as virtual.
Is it possible

public class a { public int x { get; set; } }
public class b : a { public int x { get; set; } }

public class c {
    a _a = new a();
    b _b = new b();
    public c()
    {
        int y=_a.x;
        y=_b.x;
        _b.x = y;
    }
}

Answer 1

base.x() should work inside the b type (but that isn’t what you have here).

In the “method hiding” scenario (what you have), it also largely depends on what a variable is typed as, so casting to a should work:

a tmp = _b;
tmp.x = ... // talks to a.x, not b.x

or more succinctly:

((a)_b).x = ... // talks to a.x, not b.x
