This class contains no event data; it is used by events that do not pass state information to an event handler when an event is raised. If the event handler requires state information, the application must create a subclass of this class to hold the data. For example, the AssemblyLoadEventArgs class is used to hold the data for assembly load events, and contains a System.Reflection.Assembly object that describes the loaded assembly.

For details on events, see EventHandler.
