Compiler Error C3633

  • Article

cannot define 'member' as a member of managed 'type'

CLR reference class data members cannot be of a non-POD C++ type. You can only instantiate a POD native type in a CLR type. For example, a POD type cannot contain a copy constructor or an assignment operator.

Example

The following sample generates C3633.

// C3633.cpp
// compile with: /clr /c
#pragma warning( disable : 4368 )

class A1 {
public:
   A1() { II = 0; }
   int II;
};

ref class B {
public:
   A1 a1;   // C3633
   A1 * a2;   // OK
   B() : a2( new A1 ) {}
    ~B() { delete a2; }
};
