EventDescriptor

EventDescriptor

---

System.ComponentModel (system.dll)

abstract class

This class, derived from MemberDescriptor , encapsulates the information about an event. In addition to the base functionality, you can discover the ComponentType that declares the event, and the EventType that describes the delegate for the event. You can also determine whether the delegate IsMulticast .

AddEventHandler() and RemoveEventHandler() allow you to control the binding to the encapsulated event.

 public abstract class  EventDescriptor  : MemberDescriptor {  // Protected Constructors  protected  EventDescriptor  (MemberDescriptor  descr  );    protected  EventDescriptor  (MemberDescriptor  descr  , Attribute[]  attrs  );    protected  EventDescriptor  (string  name  , Attribute[]  attrs  );  // Public Instance Properties  public abstract Type  ComponentType  {get; }    public abstract Type  EventType  {get; }    public abstract bool  IsMulticast  {get; }  // Public Instance Methods  public abstract void  AddEventHandler  (object  component  , Delegate  value  );    public abstract void  RemoveEventHandler  (object  component  , Delegate  value  ); }
