How to: Declare and Use Virtual Properties

This code sample shows how to declare and use virtual properties.

Example

// mcppv2_property_4.cpp
// compile with: /clr
using namespace System;
interface struct IEFace {
public:
   property int VirtualProperty1;
   property int VirtualProperty2 {
      int get();
      void set(int i);
   }
};

// implement virtual events
ref class PropImpl : public IEFace {
   int MyInt;
public:
   virtual property int VirtualProperty1;

   virtual property int VirtualProperty2 {
      int get() {
         return MyInt;
      }
      void set(int i) {
         MyInt = i;
      }
   }
};

int main() {
   PropImpl ^ MyPI = gcnew PropImpl();
   MyPI->VirtualProperty1 = 93;
   Console::WriteLine(MyPI->VirtualProperty1);

   MyPI->VirtualProperty2 = 43;
   Console::WriteLine(MyPI->VirtualProperty2);
}
