推荐答案

创建4个链接，分别为登录，注销，注册和用户名.登录用户后，即会话处于活动状态，隐藏两个链接，进行登录和注册，并显示其他两个链接.
如果您发现会话处于非活动状态.隐藏这两个并显示其他.

create 4 links login, logout, register and username. Once you have logged in user i.e session is active hide the two links login and register and show other two.
If you find session inactive. hide these two and show other.

我想如果登录详细信息匹配，您将重定向到Home.aspx.所以我的建议是对home.apsx.put上的页面加载进行以下代码更改.

i guess you redirect to the Home.aspx if the login details matches. so my suggestion is to do changes from page load on home.apsx.put following code.

protected void Page_Load(object sender, EventArgs e)
       {

        // this will set the username to login
        ((Label)Master.FindControl("signup2")).Text = Session["Username"].ToString();

       }

使用该代码，您可以访问母版页的控件.但是我的建议是要有单独的链接来登录和注销.您可以根据需要显示或隐藏它们.

谢谢.希望对您有所帮助.

using that code you can access master pages''s controls. But my suggestion is to have separate links to Login Log out and register. you can show or hide them as it needed.

thanks. hope this helps.
