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

From the answers so far, this seems to be the consensus:

1. The short form is best in most cases. (IsGood and !IsGood)
2. Boolean variables should be written as a positive. (IsGood instead of IsBad)
3. Since most compilers will output the same code either way, there is no performance difference, except in the case of interpreted languages.
4. This issue has no clear winner could probably be seen as a battle in the religious war of coding style.
