XmlDocument xmlDocument=new XmlDocument();
XmlElement root = xmlDocument.CreateElement("", "root", "");
xmlDocument.AppendChild(root);
XmlNode rootnode = xmlDocument.SelectSingleNode("root");
for (int i = ; i < table.Rows.Count; i++)
{
XmlElement item = xmlDocument.CreateElement("item");
item.SetAttribute("number", table.Rows[i]["number"].ToString());
item.SetAttribute("name", table.Rows[i]["name"].ToString());
item.SetAttribute("specification", table.Rows[i]["specification"].ToString());
item.SetAttribute("comments", table.Rows[i]["comments"].ToString());
root.AppendChild(item);
}
string xmlstr = xmlDocument.InnerXml;
以上是C# xml的写入方法,从数据库表读取的数据,写入xml中,保存为字符串格式。
