C#解析XML文件的代码实例分享

 XmlNodeReader reader = null;
            try
            {
                XmlDocument xd = new XmlDocument();
                xd.Load(filename);
                reader = new XmlNodeReader(xd); //创建新的XML reader
                string nodeType = null;
                while (reader.Read())
                {
                    switch (reader.NodeType)
                    { 
                         case XmlNodeType.Element://判断读到的是否为节点
                            nodeType = reader.Name;
                            break;
                        case XmlNodeType.Text://判断读到的是否为节点值
                            switch (nodeType)
                            {
                                case ROOT:
                                    rootValue = reader.Value;
                                    break;
                                default:
                                    break;
                            }
                            break;
                        default:
                            break;
                    }
                }
            }
            catch (Exception e)
            {
                System.Console.WriteLine("Read XML File Error:" + e.Message + e.StackTrace);
            }
            finally
            {
                if (reader != null)
                {
                    reader.Close();
                }
            }

最后不要忘记把reader close 掉
