Creating, Altering, and Removing Indexes
In the SQL Server Management Objects (SMO) hierarchy, indexes are represented by the Index object. The indexed columns are represented by a collection of IndexedColumn objects represented by the IndexedColumns property.
You can create an index on a XML column by specifying the IsXmlIndex property of the Index object.
