Cannot WriteXML for DataTable because Windows Search Returns String Array for Authors Property

Question

The System.Author Windows property is a multiple value string. Windows Search returns this value as an array of strings in a DataColumn. (The column's data-type is string[] or String().) When I call the WriteXML method on the resulting data-table, I get the following InvalidOperationException exception.

Is there a way to specify the data-table's xml-serializer to use for specific columns or specific data-types?

Basically, how can I make WriteXML work with this data-table?

System.InvalidOperationException: Type System.String[] does not implement IXmlSerializable interface therefore can not proceed with serialization.
