when i compile the code below and i run it, i've got the following
exception:
Unhandled Exception: System.InvalidOperationException: The type Car was
not expected. Use the XmlInclude or SoapInclude attribute to specify
types that are not known statically.
can you help me, how can i solve it? how to serialize the non primitive
type (ArrayList with the instances of the Car class)?
thanks

i try to use serialization for storing of configuration in my app.
the problem is, i've got some data stored in ArrayList, and they are
not primitive types - they are instances of classes or some structs.
so it looks like this:
[Serializable]
public class Entry
{
public string type;
public int price;
}
[Serializable]
public class CConfiguration
{
...
public ArrayList vehicle;
...
}
// in my app...
Entry e = new Entry();
e.type = "truck";
e.price = 200;
vehicle.Add( e );
but it doesnt work. how can i do that?
What doesn't work? Did your get an exception? If so, which one?
