這個是用XML作爲數據庫。
用來做一些類似欄目推廣啊，反正就是小型的窗口推廣之類的。
上代碼
- <?xml version="1.0" encoding="utf-8"?>
- <root>
- <group id="1">
- <ad id="1" lnkurl="images/pto/0.jpg" imgurl="images/pto/0.jpg">我愛好C#</ad>
- <ad id="2" lnkurl="images/pto/1.jpg" imgurl="images/pto/1.jpg">My book2</ad>
- <ad id="3" lnkurl="images/pto/2.jpg" imgurl="images/pto/2.jpg">My book3</ad>
- <ad id="4" lnkurl="images/pto/3.jpg" imgurl="images/pto/3.jpg">My book4</ad>
- </group>
- <group id="2">
- <ad id="1" lnkurl="images/pto/0.jpg" imgurl="images/pto/0.jpg">My book1</ad>
- <ad id="2" lnkurl="images/pto/1.jpg" imgurl="images/pto/1.jpg">My book2</ad>
- </group>
- </root>
以上就是XML文件
下面上ASPX文件內容

說一下思路：
因爲某些客戶，老是要在網頁的某個地方插入一些廣告。
所以就把廣告這個抽象了一下～
我主要是想分組，用來爲以後擴展做準備。
但是平常用也就一個組～所以就寫了兩個方法，根據組ID來存儲數據～
多組以後補上吧～
就是這樣了，源碼就不上傳了。
