Understanding Delegates

  • Delegates are used as pointers to methods that handle events
  • You can have multiple Delegates handle the same event. Delegates “daisy-chained” in this way do not pass the return values through the chain
  • You use AddressOf to tell the Delegate where to look for the method it needs
  • .Invoke is used to call the Delegate
  • [Delegate].Combine is used to create a chain of Delegates to handle an event
  • [Delegate].Remove is used to remove a Delegate from the event handler list
