Solution 1

XML

private XmlDocument DataTableToXmlDocument(ref DataTable dt)
<pre>{
  XmlDocument xml= new XmlDocument();
  StringBuilder sb = new StringBuilder();

  sb.Append("<?xml version='1.0' encoding='utf-8' ?>");
  sb.Append("<DocumentElement>");

  foreach (DataRow dr in dt.Rows)
  {
    sb.Append("<" + dt.TableName + ">");

    foreach (DataColumn dc in dt.Columns)
      sb.Append("<" + dc.ColumnName + ">" +
              dr[dc].ToString() +
           "</" + dc.ColumnName + ">");

      sb.Append("</" + dt.TableName + ">");
  }

  sb.Append("</DocumentElement>");
  xml.LoadXml(sb.ToString());

  return xml;
}
