Two things are obvious when implementing the Serialization pattern using a runtime environment like .NET. The first is that you don t need the WriteTo and ReadFrom methods, because a runtime environment like .NET has the ability to use metadata. Using metadata is a better solution, because this makes the serializer more flexible to do what is necessary, and it s in control of the serialization. Going back to the C++ MFC example, one of the problems was the inability to convert the serialization routines to XML. Using metadata, that problem is solved. When using a metadata approach, fine-tuning is required, and this is made possible using .NET attributes. In general, this is a good approach. What is tedious is that each serialization (binary or XML) requires its own attributes. Now imagine wanting to serialize to five different mediums does that mean you use five different sets of serialization attributes The second thing to consider is based on the first specifically, the need to use custom attributes for each medium. Those attributes are necessary, but the real question that must be asked is whether it s even possible to implement a universal Serializer pattern. Ideally, you d like to be medium independent for now and in the future. The trouble is that it s a holy grail, and not attainable. Binary serialization isn t XML serialization, and each serialization technique requires its own set of fine-tuning. And when I cover O/R mapping, there is yet another set of attributes to learn. Additionally, the following problems make implementing a Serializer pattern very complicated:

g_node_append_data() g_node_insert()

int Display() { return MessageBoxW(0, m_message, m_caption, m_type); } ~MessageBoxClass() { delete m_message; delete m_caption; } };

g_node_insert_after()

You have to specifically attach tags and do things that are specific to a serialization technique (for example, XML serialization attributes aren t usable in binary serialization). If you change the internal structure of your data class, then binary serialization can become problematic due to data members that are new or have been removed.3 XML serialization breaks the Immutable pattern, because all properties must have a get and set method, and there must be a parameterless constructor. Serialization can conflict with existing architectures and can make them less secure and maintainable. You may experience odd behavior in that what works with one serialization technique might not work with another serialization technique. In a nutshell, serialization is problematic in that you need to decide what medium you want to serialize to. Once you decide, you re locked into that medium. Of course, you can use different attributes, recompile the source code, and run the application to use another medium. But there is no magic solution with respect to serialization and universal .NET attributes. Going back to the introduction of the chapter, this is why persistence is a topic for never-ending debate.

Listing 13-15 shows the corresponding source file containing the main method. Listing 13-15. Using Your Message Box Class // native_message_box.cpp #include "native_message_box_class.h" int main() { MessageBoxClass* messageBox = new MessageBoxClass( L"Do you like this example ", L"Native message box", static_cast<MessageBoxType>(YESNOCANCEL | ICONASTERISK)); int result = messageBox->Display(); wchar_t wstr[1024]; swprintf_s( wstr, L"The dialog result was %d", result); messageBox->SetMessage(wstr); messageBox->SetType(OK); messageBox->Display(); } Try recompiling the code in Listing 13-15 with the /clr option. It works fine. You can also use the /clr:pure option in this case. As you ve seen before, the Windows headers and the CRT are both supported in pure mode. Whether you compile with /clr or not, the link command line is the same, and the executable looks similar, but they are in fact very different. Once you ve recompiled, if you want to expose the native libraries to other managed assemblies, you need to write a wrapper layer. The wrapper layer is compiled into the same assembly as the recompiled native code. Listing 13-16 shows a wrapper layer for the message box example. The code in this listing uses the marshaling library to simplify the conversions. Listing 13-16. Wrapping Your Message Box Class // message_box_wrapper.cpp #include "native_message_box_class.h" #include <vcclr.h> using namespace System; enum class MessageBoxTypeEnum { OK, OKCANCEL, ABORTRETRYIGNORE, YESNOCANCEL, YESNO, RETRYCANCEL, CANCELTRYCONTINUE, ICONHAND = 0x10, ICONQUESTION = 0x20,
