Event Handling in .NET Using C#

Conclusion

Other popular object oriented languages like, Java and Smalltalk do not have the concept of delegates. It is new to C# and it derives its root from C++ and J++. I hope that the above discussions will clear this concept to programmers who are starting out C# as their first object oriented language. If you are using Visual Studio IDE for your C# GUI development, attaching your delegate methods to the events generated by GUI controls (like mouse click on a button) can be done without you writing the code. Still, it is better to know what is going on under the hood.

    While it's very nice to know the "How" when explaining syntax, more importantly is they "why" in terms of practical real-life use within a C# application.  It would be nice of you would have included some true examples of when you would need to use one and why.

    Line:


    public class MyEventArgs  EventArgs {


    should read:


    public class MyEventArgs : EventArgs {


    Otherwise, great article!

    How can I create asynchrous events?
    Using delegates and events I get synchronous calls?
    Please advise.

    Hi,

    I am using certain, COM Components, I need to know the delegate signature, to create event handler. Is there any tools to do this? or if I need to do manually which is the easiast way to know the exact signature of those events raised by the COM components.
