Compiler Error C3185
Visual Studio 2010
'typeid' used on managed type 'type', use 'operator' instead
You cannot apply the typeid operator to a managed type; use typeid instead.
The following sample generates C3185:
// C3185a.cpp
// compile with: /clr
ref class Base {};
ref class Derived : public Base {};
int main() {
Derived ^ pd = gcnew Derived;
Base ^pb = pd;
const type_info & t1 = typeid(pb); // C3185
System::Type ^ MyType = Base::typeid; // OK
};
Managed Extensions for C++
You cannot apply typeid to a managed type; use __typeof instead.
The following sample generates C3185:
// C3185b.cpp
// compile with: /clr:oldSyntax
#using <mscorlib.dll>
__gc class Base {};
__gc class Derived : public Base {};
int main() {
Derived *pd = new Derived;
Base *pb = pd;
const type_info & t1 = typeid(*pb); // C3185
// OK
Type * t = __typeof(Base);
Type * t1 = __typeof(Derived);
};
