How to: Overload Property Accessor Methods

  • Article

It is possible to overload indexed properties.

Example

Code

// mcppv2_property_6.cpp
// compile with: /clr
ref class X {
   double d;
public:
   X() : d(0.0) {}
   property double MyProp[int] {
      double get(int i) {
         return d;
      }

      double get(System::String ^ i) {
         return 2*d;
      }

      void set(int i, double l) {
         d = i * l;
      }
   }   // end MyProp definition
};

int main() {
   X ^ MyX = gcnew X();
   MyX->MyProp[2] = 1.7;
   System::Console::WriteLine(MyX->MyProp[1]);
   System::Console::WriteLine(MyX->MyProp["test"]);
}

Output

3.4
6.8
