I was asked this during an interview. I had not heard about Single-
thread delegate or multi-thread delegate. I did a search on google and have not found any reference about either. Anyone can tell me what they are? |

Anyone can tell me what they are? Could the question have been regarding Multicast vs. Singlecast delegates? An example of multicast delegates would be that the events raised by an object may be subscribed to by multiple objects. |

What do you mean by "events raised by an object"? Can you give an example? I also am not clear about the relation between events and delegates. Can you show an intuitive example? |

Well, a form closing raises events. In an MDI application, the main application form and a child which opens a details form may subscribe to the form closing event of the lowest level form. The lowest level form just broadcasts the event (via a delegate), hence the term multicast delegate. > > I also am not clear about the relation between events and delegates. > Can you show an intuitive example? Perhaps http://msdn.microsoft.com/en-us/libr...xt(VS.71).aspx and then follow the link for "Raising an Event". |
