C# C# Objects Encapsulation and Arrays Ternary If

What does this mean: Did you include the boolean expression to evaluate?

Why doesn't this statement pass the challenge:

return (value < 0) ? textColor ="red" : textColor = "green" ;

CodeChallenge.cs 
int value = -1;
string textColor = null;

return (value < 0) ? textColor = "red" : textColor = "green";

The message isn't neaningful, the evaluation system is obviously confused about the syntax being used.

But here's a few hints:

  • a "return" is only allowed in a function, you won't use one here
  • a ternary should not contain complete statements (like assignments), just the things to choose from
  • but a ternary can be used on the right side of an assignment

Okay, I got it now. This worked: textColor = (value < 0) ? "red" :"green";

Thank you Steven!
