写 XML 文件的
//public static void SetXmlFileValue(string xmlPath, string AppKey, string AppValue)//写xmlPath是文件路径+文件名，AppKey是 Key Name，AppValue是Value public static void SetXmlFileValue(string xmlPath, string AppKey, string AppValue) { XmlDocument xDoc = new XmlDocument(); xDoc.Load(xmlPath); XmlNode xNode; XmlElement xElem1; XmlElement xElem2; xNode = xDoc.SelectSingleNode("//appSettings"
; xElem1 = (XmlElement)xNode.SelectSingleNode("//add[@key='" + AppKey + "']"; if (xElem1 != null) { xElem1.SetAttribute("value", AppValue); } else { xElem2 = xDoc.CreateElement("add"; xElem2.SetAttribute("key", AppKey); xElem2.SetAttribute("value", AppValue); xNode.AppendChild(xElem2); } xDoc.Save(xmlPath); } 读取 XML 文件节点内容 //public static void GetXmlFileValue(string xmlPath, string AppKey, ref string AppValue)//读xmlPath是文件路径+文件名，AppKey是 Key Name，AppValue是Value public static string GetXmlFileValue(string xmlPath, string AppKey) { string strValue = ""; XmlDocument xDoc = new XmlDocument(); xDoc.Load(xmlPath); XmlNode xNode; XmlElement xElem1; xNode = xDoc.SelectSingleNode("//appSettings"; xElem1 = (XmlElement)xNode.SelectSingleNode("//add[@key='" + AppKey + "']"; if (xElem1 != null) { strValue = xElem1.GetAttribute("value"; } else { // MessageBox.Show ("There is not any information!"; } return strValue; }

代码里面的调用方法 读取：GetXmlFileValue(strXmlPath, "Server"); 写入：SetXmlFileValue("setup.xml", "Server", "value");
