Try this?

        DataSet ds = new DataSet();

        DataTable dt = new DataTable();
        dt.Columns.Add("col1");
        dt.Columns.Add("col2");

        DataRow rs = dt.NewRow();
        rs[0] = "test1";
        rs[1] = "test1";
        dt.Rows.Add(rs);

        ds.Tables.Add(dt);
        ds.AcceptChanges();


        StreamWriter serialWriter;
        serialWriter = new StreamWriter(@"C:\1\test1.xml");
        XmlSerializer xmlWriter = new XmlSerializer(ds.GetType());
        xmlWriter.Serialize(serialWriter, ds);
        serialWriter.Close();
