Arguments passed to the ObjectFormatter.CustomGetValue event.
The CustomGetValueEventArgs class declares properties specific to the ObjectFormatter.CustomGetValue event. This event is designed to supply a custom value that will replace the format item in the string processed by the ObjectFormatter.Format method.
This class is inherited from the HandledEventArgs class. So, you can set the handler's Handled parameter to true. In this instance, if you have not provided a custom value, the format item will be removed from the reulting string.
