Checking login user role in razor page

Question

@if (Request.IsAuthenticated && User.Identity.Name=="administrator") {      <div id="sidebar">         <div class="module">         <ul class="menu">                             <li>@Html.ActionLink("Home", "Index", "Home")</li>                             <li>@Html.ActionLink("About", "About", "Home")</li>                             <li>@Html.ActionLink("Contact", "Contact", "Home")</li>                         </ul>          </div>          <div class="mainContent">              Hello, @User.Identity.Name !          </div>      </div> 

This is my layout if the user is authenticated as administrator but this sort of check looks no good, I need to check the role of the user not his name.

Here is the controler method

    public ActionResult AuthenticatedUserLayout(string username)      {         var lst=userContext.UserProfiles.ToList();         var user = lst.Select(u => u.UserName == username);          if(IsAdmin(Session["LoginUser"].ToString())) return View(user); else return Index();     } 

I also find that return View(user) is no good, because I don't know how to make any use of that user.

@if (Request.IsAuthenticated && User.IsInRole("Administrators")) {      <div id="sidebar">         <div class="module">            <ul class="menu">               <li>@Html.ActionLink("Home", "Index", "Home")</li>               <li>@Html.ActionLink("About", "About", "Home")</li>               <li>@Html.ActionLink("Contact", "Contact", "Home")</li>             </ul>          </div>          <div class="mainContent">              Hello, @User.Identity.Name !          </div>      </div> }
