C# 生成xml文件

//创建一个xml文件和主内容;
XmlDocument xmlDoc = new XmlDocument();
XmlElement xmlRoot = xmlDoc.CreateElement("root");
//主内容
xmlDoc.AppendChild(xmlRoot);
//选择节点
XmlNode nodeRoot = xmlDoc.SelectSingleNode("root");

//创建face方格1
XmlElement elemFace1 = xmlDoc.CreateElement("face1");
XmlElement elemFace1Img = xmlDoc.CreateElement("img");
elemFace1Img.InnerText = newFace1Img;
elemFace1.AppendChild(elemFace1Img);
XmlElement elemFace1Link = xmlDoc.CreateElement("link");
elemFace1Link.InnerText = newFace1Link;
elemFace1.AppendChild(elemFace1Link);
nodeRoot.AppendChild(elemFace1);

//创建face方格2
XmlElement elemFace2 = xmlDoc.CreateElement("face2");
XmlElement elemFace2Img = xmlDoc.CreateElement("img");
elemFace2Img.InnerText = newFace2Img;
elemFace2.AppendChild(elemFace2Img);
XmlElement elemFace2Link = xmlDoc.CreateElement("link");
elemFace2Link.InnerText = newFace2Link;
elemFace2.AppendChild(elemFace2Link);
nodeRoot.AppendChild(elemFace2);

xmlDoc.Save(strXmlFilePath);
