XmlDocument doc = new XmlDocument();
doc.Load("c:\\XMLFile1.xml");
         XmlNode node = doc.SelectSingleNode("//appSettings");
XmlNode newNode = node.CloneNode(true);
newNode.ChildNodes["name"] = "sdfsdf";
newNode.ChildNodes["replytime"] = "sdfsdfsdf";
newNode.ChildNodes["content"] = "sdfsdfsdfsd";
node.AppendChild(newNode);
doc.Save("c:\\XMLFile1.xml");
