Xml Serialization of ArrayLists in Managed C++

[Meta-Meta]

Hi,

I'm trying to use XmlSerializatio n (C++ .NET) for ArrayLists and am getting
frustrated! I'd appreaciate any explanations (the ones I found on google so
far didn't do it for me).

Here's my example :
public __gc class ServerConfig
public:
ServerConfig(vo id)
{
}

__property String* get_Description (){return description;};
__property String* get_Database(){ return database;};
__property String* get_Hostname(){ return hostname;};
__property String* get_ConnectionT ype(){return connectiontype; };

private :

String* description;
String* database;
String* hostname;
String* connectiontype;

};

and elsewhere I have an Arraylist containing ServerConfigs and would like to
serialize it :

ArrayList* srvCol = new ArrayList();
// some code to load the arraylist with ServerConfig items

How do I serialize the arraylist ? I tried variations around :

Type extraTypes[] = new Type[1];
extraTypes[0] = typeof(ServerCo nfig*);
XmlSerializer* ConfSerializer = new XmlSerializer(a lSrvCol->GetType(),
extraTypes);

but keep getting compile errors such as :
1- C2691 System::Type invalid for __gc array element
2- C3861 typeof : identifier not found

Many thanks,
