Compiler Error C3904

'property_accessor': must specify number parameter(s)

Remarks

Check the number of parameters in your get and set methods against property dimensions.

• The number of parameters for the get method must equal the number of dimensions of the property or be zero for nonindexed properties.

• The number of parameters of the set method must be one more than the number of dimensions of the property.

For more information, see property.

Examples

The following example generates C3904.

// C3904.cpp
// compile with: /clr /c
ref class X {
   property int P {
      // set
      void set();   // C3904
      // try the following line instead
      // void set(int);

      // get
      int get(int, int);   // C3904
      // try the following line instead
      // int get();
   };
};

The following example generates C3904.

// C3904b.cpp
// compile with: /clr /c
ref struct X {
   property int Q[double, double, float, float, void*, int] {
      // set
      void set(double, void*);   // C3904
      // try the following line instead
      // void set(double, double, float, float, void*, int, int);

      // get
      int get();   // C3904
      // try the following line instead
      // int get(double, double, float, float, void*, int);
   }
};
