Using C# .NET 2.0, I have a composite data class that does have the [Serializable] attribute on it. I am creating an XMLSerializer class and passing that into the constructor:

XmlSerializer serializer = new XmlSerializer(typeof(DataClass));

I am getting an exception saying: There was an error reflecting type.

Inside the data class there is another composite object. Does this also need to have the [Serializable] attribute or by having it on the top object does it recursively apply it to all objects inside?

Any thoughts?
