Hi Guys,
            What does "!" mean in front of a boolean variable,
eg.

       if (!method.IsPublic)
            {
                return false;
            }


Thank you,
Serge

That's

if method.IsPublic is true, then !method.IsPublic will give you false and vice versa

Note this does not just apply to boolean variables.  ! means not.  So therefore when you see != it means not equal.
