Compiler Error C3185

  • Artikkeli

'typeid' used on managed or WinRT type 'type', use 'operator' instead

You cannot apply the typeid operator to a managed or WinRT type; use typeid instead.

The following sample generates C3185 and shows how to fix it:

// 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
};
