Use / not use a css class with a condition – Asp.net

I am working on an MVC project,
what I need is to have custom css classes to use one when there is a user logged in to the site, and the other when accessing the site as a guest.
I thought about using a function in the controller that checks if there is a logged in account and a ViewBag to pass a true / false value to the view.
What I ask myself is:

How do I create a condition so that taking this ViewBag with the true / false value can enable a css class and disable another?

    You can use the following code to apply different css using C# variable.
    Assuming you have user and guest css class created, and you want to check is user logged in through ViewBag.UserLoggedIn:

    @{
    var cssName = "";
    if (ViewBag.UserLoggedIn)
    {
        cssName = "user";
    }
    else
    {
        cssName = "guest";
    }
}


<div class="otherclass @cssName"> Hello </div>

    You can set the Session value when User gets logged in. And check for that Session value in View

    Controller

    Public ActionResult LogIn()
{
    Session["User"] = your_value;
    ...
}

    View

    @if(Session["User"] != null)
{
    <p class="your_class">User Logged In</p>
}
else
{
    <p class="your_class">Guest User</p>
}
