Should I use `!IsGood` or `IsGood == false`?

Question

I keep seeing code that does checks like this

if (IsGood == false)
{
   DoSomething();
}

or this

if (IsGood == true)
{
   D         


        

Answer 1

For some reason I've always liked

if (IsGood)

more than

if (!IsBad)

and that's why I kind of like Ruby's unless (but it's a little too easy to abuse):

unless (IsBad)

and even more if used like this:

raise InvalidColor unless AllowedColors.include?(color)
