Confused about the ? operator in c#

Question

I want to make it so that if the value of subs is not "" then the ULs go before and after it and into the variable sL. If subs is "" then sL get the value ""

var sL = (subs != "") ? "<ul>" + subs + "</ul>" : "";

But it doesn't seem to work.

Is my format correct?

Answer 1

When in doubt, add more brackets:

var sL = subs != "" ? ("<ul>" + subs + "</ul>") : "";

However, your code should work fine already; that syntax is fine.

Answer 2

Susan, your code is correct and it works. I just tested in LinqPad. Perhaps your ss variable is null and not empty. I recommend you change your line to:

var sL = !string.IsNullOrEmply(subs) ? "<ul>" + subs + "</ul>" : "";
