Compiler Error C3638

'operator' : the standard boxing and unboxing conversion operators cannot be redefined

Remarks

The compiler defines a conversion operator for each managed class to support implicit boxing. This operator cannot be redefined.

For more information, see Implicit Boxing.

Example

The following example generates C3638:

// C3638.cpp
// compile with: /clr
value struct V {
   V(){}
   static operator V^(V);   // C3638
};

int main() {
   V myV;
   V ^ pmyV = myV;   // operator supports implicit boxing
}
