讀：

xmlDocument xmlDoc = new XmlDocument();XmlReaderSettings settings = new XmlReaderSettings();settings.IgnoreComments = true;settings.IgnoreWhitespace = true;XmlReader reader = null;reader = XmlReader.Create(fileName, settings);xmlDoc.Load(reader);//獲取名為Root的節點XmlNode root = xmlDoc.SelectSingleNode("Root");//節點的屬性,clazz屬性值XmlAttribute xmlAttr = root.Attributes["clazz"];String type = xmlAttr == null ? null : xmlAttr.Value;//遍歷這個節點的子節點foreach(XmlNode subNode in root){ //節點值 subNode.Value;}

寫：

XmlDeclaration Declaration = xmlDoc.CreateXmlDeclaration("1.0", "utf-8", null);xmlDoc.InsertBefore(Declaration, xmlDoc.DocumentElement);//創建Root節點XmlNode rootNode = xmlDoc.CreateElement("Root");xmlDoc.AppendChild(rootNode);//Root的子節點branchXmlNode branch=xmlDoc.CreateElement("branch");rootNode.AppendChild(branch);//給branch添加屬性type="branch"XmlAttribute attr=xmlDoc.CreateAttribute("type");attr.Value="branch";branch.Attributes.Append(attr);//保存到文件xmlDoc.save(fileName);
