Answer 1

If user login then mentioned the session like this:

if(login==true)
{
    sesssion["UID"]=txtUserID.Text.ToString();
} 

Then, after user click on the login link then check:

if(session["UID"]!=null)
{
    response.redirect("default.aspx");
}
else
{
    response.redirect("LoginPage.aspx");
}

尝试

Page.User.Identity.IsAuthenticated ==true

Answer 3

You have two built-in options when using Membership / Forms Authentication:

1: Use LoginStatus control instead of external link. It will automatically change to Logout when user is logged-in.

Or

2: Use LoginView to display your login and Logout links.
