1、 using System.Xml;/从配置文件读信息private static string xmlFile = System.Configuration.ConfigurationSettings.AppSettingsxmlFile; / / 创建XML / protected void infoPutIntoFile() /ProTool.XMLTools xmlTool = new ProTool.XMLTools(); /xmlTool.CreateXML(); string name = TextBox2.Text; string age = TextBox1.Text; Xm

2、lDocument xmldoc = new XmlDocument(); XmlDeclaration xmldecl; xmldecl = xmldoc.CreateXmlDeclaration(1.0, GBK, null); /xml版本号,编码(简体中文) xmldoc.AppendChild(xmldecl); XmlElement xmlelem;/加入一个根元素 xmlelem = xmldoc.CreateElement(, Information, ); xmlelem.SetAttribute(id, 01); xmldoc.AppendChild(xmlelem); /

3、添加子节点 XmlNode info = xmldoc.SelectSingleNode(Information); XmlElement objChildNode = xmldoc.CreateElement(Student); /创建XmlElement对象 objChildNode.SetAttribute(id, 1); info.AppendChild(objChildNode); XmlElement objElement = xmldoc.CreateElement(Name);/?结点和元素的区别?方法都一样. objElement.InnerText = TextBox2.T

4、ext; objChildNode.AppendChild(objElement); XmlElement age1 = xmldoc.CreateElement(Age); age1.InnerText = TextBox1.Text; objChildNode.AppendChild(age1); /保存创建好的XML文档 xmldoc.Save(xmlFile); xmldoc = null; / / 是否能连通指定的主机 / / ip 地址或主机名或域名 / true 通，false 不通 public static bool Ping(string ip) System.Net.Ne

5、tworkInformation.Ping p = new System.Net.NetworkInformation.Ping(); System.Net.NetworkInformation.PingOptions options = new System.Net.NetworkInformation.PingOptions(); options.DontFragment = true; string data = Test Data!; byte buffer = Encoding.ASCII.GetBytes(data); int timeout = 1000; / Timeout 时

6、间，单位：毫秒 System.Net.NetworkInformation.PingReply reply = p.Send(ip, timeout, buffer, options); if (reply.Status = System.Net.NetworkInformation.IPStatus.Success) return true; else return false; / / 添加子节点 / / / public XmlElement CreateFPMLNode(XmlDocument xmldoc) XmlElement FPXMNode = xmldoc.CreateEle

7、ment(business); FPXMNode.SetAttribute(id, FPMX.DZFP); FPXMNode.SetAttribute(comment, 单张发票信息); XmlElement group1 = xmldoc.CreateElement(group); FPXMNode.AppendChild(group1); XmlElement xmlelem = xmldoc.CreateElement(data); xmlelem.SetAttribute(name, wdbh); xmlelem.SetAttribute(value, 网点编号); group1.Ap

8、pendChild(xmlelem); for (int i = 0; i 2; i+) xmlelem = CreateMXNode(xmldoc); group1.AppendChild(xmlelem); return FPXMNode; / / 添加子节点 / / / public XmlElement CreateMXNode(XmlDocument xmldoc) XmlElement MXNode = xmldoc.CreateElement(business); MXNode.SetAttribute(id, MXXX); MXNode.SetAttribute(comment

9、, 票据明细信息); XmlElement group1 = xmldoc.CreateElement(group); MXNode.AppendChild(group1); XmlElement xmlelem = xmldoc.CreateElement(data); xmlelem.SetAttribute(name, hwmc); xmlelem.SetAttribute(value, 货物名称); group1.AppendChild(xmlelem); return MXNode; / / 向xml加相关的数据(增) / / public static bool addXML()

10、bool Value = true; try XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load(xmlFile); XmlNode root = xmlDoc.SelectSingleNode(business);/查找 XmlElement xe1 = xmlDoc.CreateElement(book);/创建一个节点 xe1.SetAttribute(genre, 李赞红);/设置该节点genre属性 xe1.SetAttribute(ISBN, 2-3631-4);/设置该节点ISBN属性 XmlElement xesub1 = x

11、mlDoc.CreateElement(title); xesub1.InnerText = CS从入门到精通;/设置文本节点 xe1.AppendChild(xesub1);/添加到节点中 XmlElement xesub2 = xmlDoc.CreateElement(author); xesub2.InnerText = 候捷; xe1.AppendChild(xesub2); root.AppendChild(xe1);/添加到节点中 xmlDoc.Save(xmlFile);/保存 catch return false; return Value; / / XML信息删除 / / /

12、 public static bool XmlDelete() try XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load(xmlFile); XmlNode root = xmlDoc.SelectSingleNode(business); string Node = book;/Xml是严格区分大小写的. /root.SelectSingleNode(Node).ParentNode.RemoveChild(root.SelectSingleNode(Node); root.RemoveChild(root.SelectSingleNod

13、e(Node); /保存 xmlDoc.Save(xmlFile); catch return false; return true; / / XML信息更新 / / / public static bool XmlUpdate() /XmlDoc.SelectSingleNode(/Root/StudentName=tree1/Name).InnerText = tree2; try XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load(xmlFile); XmlNode root = xmlDoc.SelectSingleNode(busi

14、ness); root.SelectSingleNode(book).Attributesgenre.Value = 雷; /保存 xmlDoc.Save(xmlFile); catch return false; return true; /XML读取（查询） public static string XmlQuery() XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load(xmlFile); XmlNode root = xmlDoc.SelectSingleNode(business); XmlNodeList NodeList = root.SelectNodes(book);/查询全部的student节点 string content = ; /循环遍历节点，查询是否存在该节点 for (int i = 0; i NodeList.Count; i+) content += NodeListi.ChildNodes0.InnerText; /查询单个节点,/表示全部匹配的元素./表示以此为根的子元素.javascript下的查询也是一样. return content;
