How to loop through controls and negate a certain tool

Question

I'd like to loop through my controls and make an IF conditional, but instead using this:

foreach(Control c in this.Controls)
    {
      if(c is TextBox) {}
    }

I'd like to do something like:

if(!c is TextBox){}

you know ? I'd like to get into the loop only if the control C is DIFFERENT of a TextBox. Of course the method I tried ! does not work with Controls. How may I deny that ?

Yep, `!c` wont work because it cannot evaluate to true/false. `!(c is TextBox)` will work because the expression in the parentheses can. — Evan L, Jun 18 '13 at 13:57
+1 Thanks for the explanation. Of course, it looks so dumb now u.u Thank you ! @Evanlewis — PlayHardGoPro, Jun 18 '13 at 13:59
@PlayHardGoPro No problem. You should consider marking Andrei's answer as the answer since he/she provided code and was the first post. — Evan L, Jun 18 '13 at 14:00

Just include condition into parenthesis:

if (!(c is TextBox)) {}
