請用心「品嚐」網絡電視精靈

市場上有許多電視軟件，所以咱們開發屬於本身的電視軟件！對於咱們初學者來講也是拿來對付行外人吹牛的資本「^_^」

本套軟件所用的技術：

01.C/S架構，數據存儲在XML文件中 

    02.簡單工廠模式

    03.繼承和多態

    04.解析XML文檔技術

   05.深刻剖析內存中數據的走向

  06.TreeView控件的使用

首先你得建立如下這麼多類！

{
    //頻道基類

12         public override void Fetch()
13         {
14             XmlDataDocument doc=new XmlDataDocument();
15             doc.Load("北京電視臺.xml");
16             if (TVlist==null)
17             {
18                 TVlist = new List<TVprogram>();
19             }

25                 {
26                     foreach (XmlNode mynode in item.ChildNodes)
27                     {
28                         TVprogram tp = new TVprogram();
29                         tp.PlayTime = DateTime.Parse(mynode["playTime"].InnerText);
30                         tp.MyProperty = mynode["meridien"].InnerText;
