I have an abstract class with a bool property:

class Abstract {
  protected bool throwException;

  protected void ThrowException{
    if (this.throwException){
      throw new MyException();
    }
  }
}

I then have two derived classes that have propertys:

class A : Abstract {
  property X {
    get { ... }
    set { ... }
  }

  property Y {
    get { ... }
    set { ... }
  }
}

class B : Abstract {
  property Z {
    get { ... }
    set { ... }
  }
}

How can I implement an scenario where the objects from class A or from
class B invoke the abstract method ThrowException every time a property
is accessed I mean, inserting the call as the first instruction of the
get/set methods, without having to coding it, just inserting the call at
runtime (modifying the accessors at runtime)?

Thanks in advance.
