Reducing Accessibility of Virtual Methods (or Not)

May 28, 2002 Written by Charles Cook

The suggested class in the previous posting relied on the fact that in C++ you can reduce the accessibility of a virtual method in a derived class:

class Parent
  void virtual Foo() { };

class Child : public Parent
  void Foo() { };

However this is not possible in Managed C++ if the classes are marked with __gc (and is incidentally also not possible in C#). Another example of how languages have to be distorted in the cause of interop with other .NET languages.
