Compiler Error C2801

'operator operator' must be a non-static member

Remarks

The following operators can be overloaded only as nonstatic members:

• Assignment =

• Class member access ->

• Subscripting []

• Function call ()

Possible C2801 causes:

• Overloaded operator is not a class, structure, or union member.

• Overloaded operator is declared static.

Example

• The following example generates C2801:

// C2801.cpp
// compile with: /c
operator[]();   // C2801 not a member
class A {
   static operator->();   // C2801 static
   operator()();   // OK
};
