XmlDocument读取XML文档

//加载指定的XML文档
            XmlDocument doc = new XmlDocument();
            doc.Load("sampledata2.xml");

            //或者通过 XmlDocument 载入 XmlTextReader 类的对象来加载XML文件
            //XmlTextReader reader = new XmlTextReader("sampledata.txt");
            //doc.Load(reader);

            //读取XML节点数据
            XmlNodeReader reader = new XmlNodeReader(doc);
            string s = "", v = "";
            while(reader.Read())
            {
                switch(reader.NodeType)
                {
                    case XmlNodeType.Element:
                        s = reader.Name;
                        break;

                    case XmlNodeType.Text:
                        {
                            if (s.Equals("Name"))
                                v = reader.Value;
                            else
                                v = reader.Value;
                        }
                        break;
                }
                Console.WriteLine(s + "\t" + v);
            }

            //关闭 XmlNodeReader
            if(reader != null)
            {
                reader.Close();
            }
