How to convert IEnumerable<table> to xml or dataset

This is the code:

IEnumerable<table> results = db_dane.ExecuteQuery<table>开发者_Python百科(query);

• table - is a database table,
• query - sql query (example: select * from table),
• db_dane - linq datacontext.

How to convert results of this query to xml or dataset?

My best thought is to convert it to a List through ToList(), and then looping through that to convert it to a data table.

Messy, but should work.
