| System.Runtime.InteropServices (mscorlib.dll) | sealed class | This class exposes the method RegisterObjectCreationCallback( ) , which specifies a delegate that manufactures instances of a managed type. Use this to build managed types that extend unmanaged types. Since a managed type cannot directly inherit from an unmanaged type, the managed type needs to aggregate an instance of the unmanaged type. The delegate that you register with RegisterObjectCreationCallback( ) takes care of creating the unmanaged type. public sealed class ExtensibleClassFactory { // Public Static Methods public static void RegisterObjectCreationCallback (ObjectCreationDelegate callback ); } |
