c#与XML

用c#写入xml的方法如下：

#region "生成XML"
                    // 创建一个表示所要生成的XML文件路径的字符串。如果该路径指向NTFS分区，则需要相关的访问权限。
                    fileName =  "testHisMon.xml";
                    // 创建一个写入XML数据的文件流
                    FileStream myFileStream = new FileStream(fileName, System.IO.FileMode.Create);
                    // 使用文件流对象创建一个XmlTextWriter对象
                    XmlTextWriter writer = new XmlTextWriter(myFileStream, Encoding.UTF8);
                    writer.Formatting = Formatting.Indented; //缩进格式
                    writer.Indentation = 4;
                    writer.WriteStartDocument();
                    writer.WriteStartElement("OnlineMonXML");
                    writer.WriteAttributeString("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance");
                    writer.WriteAttributeString("xsi:noNamespaceSchemaLocation", "D:\\ming\\OnlineMon\\XMLData\\GDHB_OnlineMonXML.xsd");
                    writer.WriteAttributeString("version", "0.09.0005");
                    // OnlineMonData
                    writer.WriteStartElement("OnlineMonData");
                    // Stations
                    writer.WriteStartElement("Stations");
                    // Station
                    writer.WriteStartElement("Station");
                    writer.WriteAttributeString("strStationType", "污染源自动监测");
                    writer.WriteAttributeString("strAreaID", _strAreaID);
                    writer.WriteAttributeString("nStationID", _stationID);
                    writer.WriteAttributeString("strPassword", _strPassword);
                    // Points
                    writer.WriteStartElement("Points");
                    // Points
                    writer.WriteStartElement("Point");
                    writer.WriteAttributeString("strAreaID", _strAreaID);
                    writer.WriteAttributeString("nStationID", _stationID);
                    writer.WriteAttributeString("nPointID", pointID);
                    // MonDatas
                    writer.WriteStartElement("MonDatas");
                    
                    // return;
                    
                    writer.WriteEndElement();
                    writer.WriteEndElement();
                    writer.WriteEndElement();
                    writer.WriteEndElement();
                    writer.WriteEndElement();
                    writer.WriteEndElement();
                    writer.WriteEndDocument();
                    writer.Close();
                    myFileStream.Close();
