An indexed property was declared incorrectly. For more information, see How to: Use Properties in C++/CLI.

Example

The following sample generates C3799 and shows how to fix it.

// C3799.cpp
// compile with: /clr /c
ref struct C {
   property int default[] {   // C3799
   // try the following line instead
   // property int default[int] {
      int get(int index) { return 0; }
      void set(int index, int value) {}
   }
};
