I have an application where I would like to show list of all the logged in users in a partial view. I know we can do it using memberships, but not sure how to implement it exactly.
my Controller code
[Authorize(Roles = "Admin")]
public ActionResult ActiveUsers()
{
//ViewBag.Message = "Your contact page.";
// MembershipUserCollection users;
// Bind users to ListBox.
List<MembershipUser> onlineUsers = new List<MembershipUser>();
foreach (MembershipUser user in Membership.GetAllUsers())
{
if (user.IsOnline)
{
onlineUsers.Add(user);
HttpRuntime.Cache["onlineUsers"] = onlineUsers;
}
}
return View();
}
View
@if (HttpRuntime.Cache["onlineUsers"] != null)
{
List<string> LoggedOnUsers = (List<string>)HttpRuntime.Cache["onlineUsers"];
if (LoggedOnUsers.Count > 0)
{
<div class="ChatBox">
<ul>
@foreach (string user in LoggedOnUsers)
{
<li>
<div class="r_row">
<div class="r_name">@Html.Encode(user)</div>
</div>
</li>
}
</ul>
</div>
}
}
With the above code when I access the active users page, it threw me following exception
Server Error in '/' Application.
Specified method is not supported.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Can I get a better way to do it?
