How to check user is "logged in"?
I am using form authentication with below method in my ASP.NET application
FormsAuthentication.RedirectFromLoginPage(txtUsername.Text, true);
How do I check whether user 开发者_开发问答is logged in or not? And how can I get the user name of a logged in user?
I managed to find the correct one. It is below.
bool val1 = System.Web.HttpContext.Current.User.Identity.IsAuthenticated
EDIT
The credit of this edit goes to @Gianpiero Caretti who suggested this in comment.
bool val1 = (System.Web.HttpContext.Current.User != null) && System.Web.HttpContext.Current.User.Identity.IsAuthenticated
The simplest way:
if (Request.IsAuthenticated) ...
if (User.Identity.IsAuthenticated)
{
Page.Title = "Home page for " + User.Identity.Name;
}
else
{
Page.Title = "Home page for guest user.";
}
Easiest way to check if they are authenticated is Request.User.IsAuthenticated
I think (from memory)
