Using ternary operator to output a string containing whitespace in Razor

Question

I'm trying to use a ternary operator in Razor, similar to this question, but what I want to output contains whitespace. This code

@(selectedGoal == null ? "" : "value=" + selectedGoal.Name)

should produce

value="Goal 3"

as the value of selectedGoal.Name is "Goal 3". Instead, I get

value="Goal" 3

which is no good. I've tried a bunch of different combinations of escaped quotes, @ symbols and no @ symbols, and I just can't get this to work, i.e.

@(selectedGoal == null ? "" : "value=" + "selectedGoal.Name")
@(selectedGoal == null ? "" : "[email protected]")

and then I just get something like

value="selectedGoal.Name"

Anyone know how this should be done?

Nothing you are showing would produce those results. Clearly, the problem is in whatever sets the value of selectedGoal.Name. — Erik Funkenbusch

I use selectedGoal.Name elsewhere in the page and it works fine, no misplaced quotes or anything. — wohanley

Something is placing those quotes, and the code you have shown is not doing it. — Erik Funkenbusch

Does this answer your question? How to use ternary operator in razor (specifically on HTML attributes)? — Michael Freidgeim

Your value attribute is missing its own quotes, so they are being automatically added before the space. Try moving value outside of the expression.

value="@(selectedGoal == null ? "" : selectedGoal.Name)"

Comes out like this: value=""Goal" 2".

@wohanley, I'm not sure where those extra sets of quotes would come from. Does .Name actually contain the quotes as part of the string?

It really, really shouldn't, but if this Razor is correct then maybe that's the only possibility. I'll triple-check.

There should be nowhere that quotes are added to Name, and it's working fine (that is, quote-free) in other places on the same page.

@wohanley, you're right try the updated answer. I think @ is encoding the quotes again. My previous answer wrapped with @Html.Raw instead of just @ seems to work, but this way is a little cleaner anyways.

What about

@(selectedGoal == null ? "" : "value=\"" + selectedGoal.Name + \")

Or you can try rendering them directly as an HTML block, using my method on Html literal in Razor ternary expression

It will escape the HTML encode the quotes, so this won't work. Did you just guess?
