什么？还是看着眼熟？没错，是不是和前边我定义的那个类差不多？是，本来asp.net就
是把这个页当作一个对象，注意类定义的那行代码：public class Register :
System.Web.UI.Page ， 前面你可以理解，是定义一个Register对象，那:号后面的Syst
em.Web.UI.Page是什么意思呢？它说明这个Regsiter类是System.Web.UI.Page类的派生
类（子类），也就是说Register类除了自己成员变量、属性、方法外，还继承
System.Web.UI.Page类的所有公共(public)或保护(protected)成员变量、属性和方法。
明白了这些，你可以
安心坐下来研究代码了，做好下面关于表单验证内容的学习准备。
