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

[jacek]

member function of Derived class Derived::bar() should be hidden from the derived class object.... and the object of Derived class should called Base::bar() member function...

Are you talking about this?

#include <iostream>
 
class Base
{
   public:
      void foo() { std::cout << "Base::foo" << std::endl; }
      void bar() { std::cout << "Base::bar" << std::endl; }
};
 
class Derived : public Base
{
   public:
      void foo() { std::cout << "Derived::foo" << std::endl; }
};
 
int main()
{
   Derived d;
 
   d.foo();
   d.bar(); // <--
 
   return 0;
}

#include <iostream>
 
class Base
{
   public:
      void foo() { std::cout << "Base::foo" << std::endl; }
      void bar() { std::cout << "Base::bar" << std::endl; }
};
 
class Derived : public Base
{
   public:
      void foo() { std::cout << "Derived::foo" << std::endl; }
};
 
int main()
{
   Derived d;

   d.foo();
   d.bar(); // <--
 
   return 0;
}

Output:

Derived::foo()
Base::bar()
