xml与datatable互转

DataTable转Xml --dt为已获得的DataTable

StringBuilder xml = new StringBuilder();XmlWriter writer = XmlWriter.Create(xml);XmlSerializer serializer = new XmlSerializer(typeof(DataTable));serializer.Serialize(writer, dt);writer.Close();xml.ToString();

Xml转DataTable --只能从DataSet转 xml为上面的xml变量

DataSet dss = new DataSet();dss.ReadXml(new StringReader(xml.ToString()));
