XmlDocument doc = new XmlDocument();
            doc.Load("e:\\1.txt");
            XmlNodeList nodes = doc.DocumentElement.SelectNodes("Type");
            foreach (XmlNode node in nodes)
            {
                //node.InnerText，这个就是name的内容，自己判断
            }

            string Name1="";

           string Name3 = "";
           string xmlstr = "<?xml version=\"1.0\" encoding=\"utf-8\"?>";

           XmlElement root = doc.DocumentElement;
           XmlNodeList nodes = root.SelectNodes("Type");
           for (int i = 0; i < nodes.Count; i++)
           {
               XmlNode xmlnode =nodes.Item(i);
               switch(xmlnode.SelectSingleNode("ID").InnerText)

          //Name

找ID为1的节点：
XmlNode incrementPidUploadNode = domIncrementIndex.SelectSingleNode("/Group/Type/ID[text()='" + 1 + "']");
然后找下个节点，取值便可
