Gets a value indicating whether the font is a member of SystemFonts.
Assembly: System.Drawing (in System.Drawing.dll)
When the user changes the system font, the property could return true, even if the font is not actually a system font. To avoid this situation, if you are using system fonts in your application, you should track user preference changes by handling the UserPreferenceChanging or UserPreferenceChanged event.
