XML转JSON

              XmlDocument doc = new XmlDocument();
                doc.Load(path);
                string strXml = doc.InnerXml;
                XmlNode node = doc.SelectSingleNode("data");  //data  根节点名称
                string result = Newtonsoft.Json.JsonConvert.SerializeXmlNode(node);


                //string pathFile = System.IO.Path.GetFullPath("../../file/josn.txt");
                FileStream fs = new FileStream(@"../../file/josn.txt", FileMode.Create);

                
                //获得字节数组
                byte[] data = System.Text.Encoding.Default.GetBytes(result); 
                //开始写入
                fs.Write(data, 0, data.Length);
                //清空缓冲区、关闭流
                fs.Flush();
                fs.Close();
