Answer 1

ds.ReadXml得到datatset，下面就简单了

Answer 2

用xmlDocument阿XmlDocument doc = new XmlDocument();          
            doc.Load("test.xml");            XmlNodeList node = doc.SelectNodes("/list/*");//取得list下面的所有节点
             foreach (XmlNode n in node)
            {
                if (n.ChildNodes.Count > 0)//判断，也就是list1,list2等节点
                {
                    n.ChildNodes[0].InnerText;//type element
                    n.ChildNodes[1].InnerText;//method element
                }
            }
大概这个意思

Answer 3

或者你可以通过序列化的方式

Answer 4

这个好象事先需要定义一个XMLSCHEMA....
不过确实比较简单~

Answer 5

序列化...1个list 作为 1个对象

Answer 6

楼上的都不错第一楼方法最好，你可以接机会总结XML操作的这个技术点，

Answer 7

可以用DataSet ,可是怎样处理DataSet
