Razor If/Else conditional operator syntax

Question

Not having much luck, I have the following if/else statement in Razor which works perfectly

<small>
  @if(deletedView){
     @:Deleted
  } 
  else {
     @:Created
  } by
</small>

I am trying to do something like this:

<small>
  @(deletedView) ? @:Deleted : @:Created by
</small>

But that fails miserably. What is the proper syntax?

You need to put the entire ternary expression in parenthesis. Unfortunately that means you can't use "@:", but you could do something like this:

@(deletedView ? "Deleted" : "Created by")

Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set.

@Andrew Nurse, As per you have mentioned, "Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set". I would like to know what all operators are part of that set? Thanks! – Vikram May 29 '14 at 15:54
