Join Bruce Van Horn for an in-depth discussion in this video Alternate if-else formats and the ternary operator, part of C# Essential Training: 2 Flow Control, Arrays, and Exception Handling.
- So we've seen a basic If statement at work.…I thought I'd show you a couple of…different formats for this.…Let's add another method to our flow control class.…This one is going to be very similar…to what we have on line ten.…This is going to be public bool IsYourFavoriteColorRed.…And this time I wanted to show you that…if you have only one thing in your If statement,…as we actually do in the blue version of this,…we don't really need to put the curly braces in there.…
So it looks like this.…We can say if(color.ToLower() == "red")…then we'll return true.…Otherwise, there's no need for an else here,…"return false;".…The reason this works is because…if it is actually red, then the statement returns here,…it exits the method and line 12 never actually runs.…But if it's false then it falls through to line 12,…and line 12 handles the return.…
It's a slightly more terse way of writing…what we have down here in the blue version.…And if you like terse, let me show you…an even more terse method,…and that's the ternery operator.…
