Serializing Collections with Interface members

I have a collection class and in order to make it type safe etc , I only add
and retrive members of Interface types.

But during XMLSerialization I get errors.

Is there any workaround ?

public class OrgRatingCollection:CollectionBase

{

public void Add(IRating item)

{

this.List.Add(item);

}

public IRating this[int index]

{

get

{

return (IRating) this.List[index];

}

set

{

this.List[index] = value;

}

}

}

}to serialize a collection, all object in the collection must be
serializable. defining a interface has no impact.
