Compiler Error C2844
'member' : cannot be a member of interface 'interface'
An interface class (C++ Component Extensions) cannot contain a data member unless it is also a property.
Anything other than a property or member function is not allowed in an interface. Furthermore, constructors, destructors, and operators are not allowed.
The following sample generates C2844:
// C2844a.cpp
// compile with: /clr /c
public interface class IFace {
int i; // C2844
// try the following line instead
// property int Size;
};
The following sample generates C2844:
// C2844b.cpp
// compile with: /clr:oldSyntax /c
#using <mscorlib.dll>
__gc __interface IFace {
int i; // C2844
// try the following line instead
// __property int Size { get; set; };
};
