数组类型问题

Question

假如有个fccom.xml文件！用循环把LIST读取出来。ArrayList l = new ArrayList();XDocument doc = XDocument.Load("fccom.xml");            var list = (from node in doc.Root.Descendants("FcCom")                        //where node.Attribute("id").Value == id                        select new                        {                            scompany=node.Attribute("scompany").Value,                            id=node.Attribute("id").Value                        }).Take(12);            foreach (var attr in list)            {　　　　　　　l.add(attr.toString());            }请问在这循环中我应该用什么来存放attr好呢！像我用ArrayList 来存放，可返回的值却是System.Collections.ArrayList这种类型的。
