Question

Is it possible to call the base Constructor at spicific point in the constructer of the subclass like:

public class SuperClass
{
  public SuperClass(Object myObject)
  {
     // init some values ...
  }
}

public class SubClass: SuperClass
{
  public SubClass(): base(Object myObject)
  {
     //Check some preconditions
     base(myObject);
     // Do some other stuff
  }
}

Answer 1

No, it’s not possible.

One way to achieve this behavior you could extract the contents of the base constructor out into a method and then call that method from the subclass.

Another less closely tied method would be to just not use inheritance here. It’s possible that this is a situation in which composition would make more sense. (It’s impossible to say for sure without knowing more information though.)
