XML 数据绑定datagridview

DataTable dt = new DataTable();
                dt.Columns.Add("name", typeof(string));
                dt.Columns.Add("value", typeof(int));
                dt.Columns.Add("para", typeof(string));
                string filename = AppDomain.CurrentDomain.BaseDirectory + "DefaultStart.xml";
                XmlDocument xmlDoc = new XmlDocument();
                xmlDoc.Load(filename);
                XmlNode xmlNode = xmlDoc.SelectSingleNode("DocumentElement");
                string xmlData = xmlNode.InnerXml;

                //加载XML数据，也可XElement.Load("文件名")
                var xdoc = XElement.Parse(xmlData);
                var m = (from mod in xdoc.Elements("Node")
                         select new
                         {
                             //给DataTabel添加数据行
                             a = dt.Rows.Add(mod.Element("name").Value, mod.Element("value").Value, mod.Element("para").Value)
                         }).ToList();

                dataGridView1.DataSource = dt;
