比如从test1.aspx页面点击按钮进入test2.aspx页面，如果想在test2.aspx页面中得到test1.aspx页面中某些控件的值.
test1.aspx前台代码,
这里要注意的按钮一定要设置postbackurl="test2.aspx" 属性,不能在它的CS代码中比如用Redirect 的方法
--> 1<%
@ Page Language="C#" AutoEventWireup="true" CodeFile="test1.aspx.cs" Inherits="Print_test1" %>

在test2.aspx.cs
代码中使用类似((TextBox)this.PreviousPage.FindControl("TextBox1")).Text 的方法来访问前页的属性或方法.
