1.一个循环

  #region  一个循环
            //解析xml找一个工具 一个类XmlDocument
            //1.1 在Cache中构建一个新的文档对象
            XmlDocument doc = new XmlDocument();
            //1.2用Load渲染数据 doc对象
            doc.Load("XMLFile1.xml");
            //1.3属性DocumentElement;
            XmlNode root = doc.DocumentElement;
            foreach (XmlNode item in root.ChildNodes)
            {
                string id = item.Attributes["id"].Value;
                Console.WriteLine("编号;"+id);
                Console.WriteLine("名称:"+item["Name"].InnerText);
                Console.WriteLine("价格:" + item["Price"].InnerText);
                Console.WriteLine("CPU:" + item["Cpu"].InnerText);

2.两个循环

            //1.2用Load渲染数据 doc对象
            doc.Load("XMLFile1.xml");
            //1.3属性DocumentElement;
            XmlNode root = doc.DocumentElement;
            foreach (XmlNode item in root.ChildNodes)
            {
                foreach (XmlNode Child in item.ChildNodes)
                {
                    switch (Child.Name)
