Question

I am trying to serialize a class several of the data-members are Nullable objects, here is a example

[XmlAttribute(\"AccountExpirationDate\")]
public Nullabl         


        

Answer 1

You can only serialize it as an XmlElement, not as an XmlAttribute, as the representation is too complex for an attribute. That's what the exception is telling you.
