XmlSerializer serialize generic List of interface

Question

I\'m trying to use the XmlSerializer to persist a List(T) where T is an interface. The serializer does not like interfaces. I\'m curious if there is a simple way to serializ

Answer 1

Do you have to use XmlSerializer? This is a known issue with XmlSerializer.

You can use BinaryFormatter to save to a stream:

BinaryFormatter bf = new BinaryFormatter();
MemoryStream ms = new MemoryStream();
bf.Serialize(ms, animals);

Other alternative is to use WCF's DataContractSerializer and provide types using KnownType attribute.
