?: condition in Razor C#

I'm Migrating an old website to ASP.Net MVC 5, I had a link like this:

<a href="/contact"><%=User.Identity.IsAuthenticated?"Support":"Contact Us"%></a>

I googled and tried several things and I ended up with the following code:

<a href="/contact">@if{User.Identity.IsAuthenticated){@Html.Raw("Support");}else{@HtmlRaw("Contact Us");}</a>

But this seems not to be the solution as it is much more complicated than the first one, while Razor is created for the simplicity

Just wrapping your ternary expression in @() should work. 

<a href="/contact">@(User.Identity.IsAuthenticated ? "Support" : "Contact Us")</a>

Edit:

If you need HTML elements, you can wrap your ternary expression in @Html.Raw().

i.e.

@Html.Raw(User.Identity.IsAuthenticated ? "<div>Support</div>" : "Contact Us")

I think this one is more readable.

@if(User.Identity.IsAuthenticated){
   <a href="/contact">Support</a>
}
else{
    <a href="/contact">Contact Us</a>
}

The operator you are referring to is called the ternary operator, it is used to have inline if statements

In your example, it can be used like so

<a href="/contact">@(User.Identity.IsAuthenticated ? "Support" : "Contact Us")</a>
