How to hide the action link?

I want to send a simple request to my controller asking if the person who is logged in is admin or not?

I do not want to use IsAuthenticated option

Answer was simple

                      @if (Convert.ToBoolean(ViewData["admin"])==true)
                      {

                           <li>@Html.ActionLink("Admin", "Admin", "Admin") </li>

}

You may also be able to do something like this:

@if (Page.User.IsInRole("admin"))
{
   <li>@Html.ActionLink("Admin", "Admin", "Admin") </li>
}

if (User.IsInRole("Admin")) 
{ 
    <li>@Html.ActionLink("Admin", "Admin", "Admin") </li>
}
