DataSet对XML进行生成、更新、添加、删除等操作
//创建一个数据集 DataSet dsTradeNews = new DataSet(); //读取XML文件用于绑定到DataGrid上 dsTradeNews.ReadXml(@"D:\CorpInfo.xml",XmlReadMode.Auto); //创建一个表 DataTable dtTradeNews = new DataTable("TradeNews"); //创建列 DataColumn dcSimpleName = new DataColumn("SimpleName",Type.GetType("System.String")); DataColumn dcCode = new DataColumn("Code",Type.GetType("System.String")); //将列加入到表中 dtTradeNews.Columns.Add(dcSimpleName); dtTradeNews.Columns.Add(dcCode); //创建行并为每列赋值 DataRow drTradeNew = dtTradeNews.NewRow(); drTradeNew["SimpleName"] = "公司"; drTradeNew["Code"] = "888888"; //将表加入数据集中 dsTradeNews.Tables.Add(dtTradeNews); //生成XML文件或覆盖XML文件 try 
{
dsTradeNews.WriteXml(@"D:\CorpInfo.xml");
} catch(Exception ex) { Response.Write("生成XML文件产生异常：" + ex.Message); return ; } dgTradeNews.DataSource = dsTradeNews.Tables["TradeNews"].DefaultView; dgTradeNews.DataBind();另一种操作方式：
利用：doc、XmlNode //创建XmlDocument的实例 private XmlDocument doc = new XmlDocument(); private XmlElement X_TR; private XmlElement X_Script; private XmlElement X_Connection; private XmlElement X_Time; private XmlElement X_Name; private XmlElement X_Path; private XmlText X_Script_Text; private XmlText X_Connection_Text; private XmlText X_Time_Text; private XmlText X_Name_Text; private XmlText X_Path_Text; const string cfileName = "XMLnote.xml"; const string XmlFile = "ScriptMain"; const string XmlTab = "TAB"; const string XmlConnection = "Connection"; const string XmlScript = "Script"; const string XmlPath = "Path"; const string XmlName = "Name"; const string XmlTime = "Time"; //XML文档起点 private string XMLOP = ""; doc.Load(cfileName); XmlNode Root = doc.DocumentElement; string XMLstart = GetXMLOP(); XmlNode XNode = doc.SelectSingleNode(XMLstart); if(XNode != null) { //产生行元素 X_TR = doc.CreateElement("",XmlTab,""); //产生Script元素 X_Connection = doc.CreateElement("",XmlConnection,""); X_Script = doc.CreateElement("",XmlScript,""); X_Path = doc.CreateElement("",XmlPath,""); X_Name = doc.CreateElement("",XmlName,""); X_Time = doc.CreateElement("",XmlTime,""); //产生该元素的文本 X_Connection_Text = doc.CreateTextNode(XMLLogList.Connection); X_Script_Text = doc.CreateTextNode(XMLLogList.Script); X_Path_Text = doc.CreateTextNode(XMLLogList.Path); X_Name_Text = doc.CreateTextNode(XMLLogList.Name); X_Time_Text = doc.CreateTextNode(XMLLogList.Time.ToString()); //向Script元素添加文本 X_Connection.AppendChild(X_Connection_Text); X_Script.AppendChild(X_Script_Text); X_Path.AppendChild(X_Path_Text); X_Name.AppendChild(X_Name_Text); X_Time.AppendChild(X_Time_Text); //将Script元素添加到行节点下 X_TR.AppendChild(X_Connection); X_TR.AppendChild(X_Script); X_TR.AppendChild(X_Path); X_TR.AppendChild(X_Name); X_TR.AppendChild(X_Time); //将行元素添加到父节点下 XNode.AppendChild(X_TR); } doc.Save(cfileName);另一种操作XML的方式：
利用FileStream、XmlTextWriter操作XML文件 //第一次生成XML记录文件 FileStream XMLStream = new FileStream(cfileName,FileMode.CreateNew); XmlTextWriter XmlWrite = new XmlTextWriter(XMLStream,Encoding.Unicode); XmlWrite.Formatting = Formatting.Indented; try { XMLBuilWriter(XmlWrite,XMLLogList); XmlWrite.Close(); } catch(Exception ex) { cRemark = ex.Message.ToString(); }//开始创建XML文件 static void XMLBuilWriter(XmlWriter Write,LogListAttribute XMLLogList) { Write.WriteStartElement(XmlFile); Write.WriteStartElement(XmlTab); Write.WriteElementString(XmlConnection,XMLLogList.Connection); Write.WriteElementString(XmlScript,XMLLogList.Script); Write.WriteElementString(XmlPath,XMLLogList.Path); Write.WriteElementString(XmlName,XMLLogList.Name); Write.WriteElementString(XmlTime,DateTime.Now.ToLongTimeString()); Write.WriteEndElement(); Write.WriteEndElement(); }
