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

We tend to do the following here:

if(IsGood)

or

if(IsGood == false)

The reason for this is because we've got some legacy code written by a guy that is no longer here (in Delphi) that looks like:

if not IsNotGuam then

This has caused us much pain in the past, so it was decided that we would always try to check for the positive; if that wasn't possible, then compare the negative to false.
