.NET实现XML与DataTable互转的实例代码

private string ConvertDataTableToXML(DataTable xmlDS)

 {
 MemoryStream stream = null;
 XmlTextWriter writer = null;
 try
 {
 stream = new MemoryStream();
 writer = new XmlTextWriter(stream, Encoding.Default);
 xmlDS.WriteXml(writer);
 int count = (int)stream.Length;
 byte[] arr = new byte[count];
 stream.Seek(0, SeekOrigin.Begin);
 stream.Read(arr, 0, count);
 UTF8Encoding utf = new UTF8Encoding();
 return utf.GetString(arr).Trim();
 }
 catch
 {
 return String.Empty;
 }
 finally
 {
 if (writer != null) writer.Close();
 }
 } 
 private DataSet ConvertXMLToDataSet(string xmlData)
 {
 StringReader stream = null;
 XmlTextReader reader = null;
 try
 {
 DataSet xmlDS = new DataSet();
 stream = new StringReader(xmlData);
 reader = new XmlTextReader(stream);
 xmlDS.ReadXml(reader);
 return xmlDS;
 }
 catch (Exception ex)
 {
 string strTest = ex.Message;
 return null;
 }
 finally
 {
 if (reader != null)
 reader.Close();
 }
 }
