compare a brush and color

Question

if (backBrush == SystemColors.ActiveCaption)

This fails. Says you can't compare a brush and a color.

How do I find the color of the brush?

Answer 1

If backBrush is a SolidColorBrush (based on what you're trying to do it probably is) you can use:

if(((SolidColorBrush)backBrush).Color == SystemColors.ActiveCaption)

Answer 2

If the brush is a SolidBrush you can compare the Color member of the brush. Something like this.

SolidBrush solidBrush = brush as SolidBrush;
if (solidBrush != null && solidBrush.Color == SystemColors.ActiveCaption)
{
  // ....
}

The above is for WinForms, for WPF you would use SolidColorBrush rather than SolidBrush.
