定义频道父类
 public abstract class ChannelBase

        public  List<Tvprogeam>tv{get;set;}

定义一个工厂类

                   break;
           }
           return channel;
       }

//从XML文件中遍历出，然后存入到list集合中
 public class ChannlManager
    {
      public List<ChannelBase> FullChannels{ get; set; }

//遍历出凤凰卫视xml文件，将其存放在list集合中

将北京电视台xml文件遍历出然后存入list<Tvprogeam>
 public static List<Tvprogeam> list = new List<Tvprogeam>();
        public override void fetch()

            doc.Load("北京电视台.xml");
            XmlNode root = doc.DocumentElement;
            foreach (XmlNode item in root.ChildNodes)
            {
                if (item.Name.Equals("tvProgramTable"))
