推荐答案
如果您是ASP.NET的新手并希望实现页面访问安全性，我建议您开始查看：演练：管理带角色的网站用户 [ ^ ]
If you are new to ASP.NET and wanted to implement page access security, I'd suggest you to start looking at: Walkthrough: Managing Web Site Users with Roles[^]
如果您不想进入通用的东西，可以使用Master.FindControl来访问母版页的控件。您的内容页面......
If you do not want to get into something generic, you can access controls of the master page using Master.FindControl from your content page...
