"new" modifier explicitly hide a member inherited from a base class in C#

[wysota]

There are many ways. The simplest is to prefix all member variables, for example "m_invoke" instead of "invoke". Another is to use a separate internal namespace:

class x {
public:
//...
  void invoke() { xpriv::invoke++; }
private:
  namespace xpriv {
    int invoke;
  }
};

class x {
public:
//...
  void invoke() { xpriv::invoke++; }
private:
  namespace xpriv {
    int invoke;
  }
};

You can also use a data-pointer and hide all member variables in a separate object.
