任務：從一個頁跳到另一個頁面，另一個頁面檢查第一個頁面的信息。
1.文件組成:w1.aspx(此頁面從w1 class 繼承而來),w1.aspx.cs(此文件中定義了class: w1)
w2.aspx,w2.aspx.cs(此文件中定義了class:w2)
2.在頁面w1上有button1按鈕,其單點事件中輸入：
Server.Transfer("w2.aspx");
在w1.aspx.cs 的w1 class中公開button1
public button Button1
{
get {return button1;}
}
然後在w2.aspx中的首第一行加入<%@ Reference Page="w1.aspx" %> 注意：一定是第一行
在w2.aspx.cs的w2 class 中聲明對w1的引用：
public w1 SourPage;
在w2中檢查w1的button1的信息：
private void page_load(object sender,system.EventArgs e)
{
SourPage=(w1)Context.Handler;
if Button1.text.ToUpper()=="GOTO W2!!!"
Response.Write("<h3>OK,Come on,w1!!!</h3>");
}
w1.aspx
