Compiler Error C2819

 

The latest version of this topic can be found at Compiler Error C2819.

type 'type' does not have an overloaded member 'operator ->'

You need to define operator->() to use this pointer operation.

The following sample generates C2819:

// C2819.cpp  
// compile with: /c  
class A {  
   public:  
      int i;  
};  
  
class B {};  
  
void C(B j) {  
   j->i;   // C2819  
}  
  
class D {  
   A* pA;  
  
   public:  
      A* operator->() {  
         return pA;  
      }  
};  
  
void F(D j) {  
   j->i;  
}  

C2819 can also occur when using C++ Stack Semantics for Reference Types. The following sample generates C2819:

// C2819_b.cpp  
// compile with: /clr  
ref struct R {  
   void Test() {}  
};  
  
int main() {  
   R r;  
   r->Test();   // C2819  
   r.Test();   // OK  
}
