Remarks

As Microsoft describes in their MSDN documentation, the event model in the .NET Framework is based on having an event delegate that connects an event with its handler. To raise an event, two elements are needed:

  • A class that holds the event data. This class must derive from the base class EventArgs.
  • A delegate that points to a method that provides the response to the event.
When using the BeginConnect method, the class that holds the event data is the ExceptionEventArgs class. A method must be created with the same signature as the delegate. In this example that would mean a method would have to be defined to accept two arguments (an object and a ExceptionEventArgs) and return void. Once this has been done, the delegate must be "connected" to the handling event. This is done by adding an instance of the delegate to the event.

For more information about event handler delegates, see the Using Events In PowerTCP topic.
