new (new slot in vtable) 

In a /clr compilation, new indicates that a virtual member will get a new slot in the vtable; that the function does not override a base class method.

Remarks

new causes the newslot modifier to be added to the IL for the function. For more information about newslot, see:

• MethodInfo.GetBaseDefinition Method

• MethodAttributes Enumeration

The following sample shows the effect of new.

Example

// newslot.cpp
// compile with: /clr
ref class C {
public:
   virtual void f() {
      System::Console::WriteLine("C::f() called");
   }

   virtual void g() {
      System::Console::WriteLine("C::g() called");
   }
};

ref class D : public C {
public:
   virtual void f() new {
      System::Console::WriteLine("D::f() called");
   }

   virtual void g() override {
      System::Console::WriteLine("D::g() called");
   }
};

ref class E : public D {
public:
   virtual void f() override {
      System::Console::WriteLine("E::f() called");
   }
};

int main() {
   D^ d = gcnew D;
   C^ c = gcnew D;

   c->f();   // calls C::f
   d->f();   // calls D::f

   c->g();   // calls D::g
   d->g();   // calls D::g

   D ^ e = gcnew E;
   e->f();   // calls E::f
}

Output

C::f() called
D::f() called
D::g() called
D::g() called
E::f() called
