如何将套接字转换为处理程序类？

Question

I created a handler class which extends the System.Net.Sockets.Socket class. I am not familiar with casting types, inheritance or C# for that matter, so how do I cast a regular Socket to my Handler class?

I've tried this:

Handler handler = (Handler)socket; 

But I get an InvalidCastException. Also, I do not want to extend the class by using a container class.

Thanks.

You just can't, that's not how inheritance works.

You can't treat some Socket as your Handler . It works the other way around: you can treat your Handler as a Socket .

If you want to use your Handler , you need to create an instance of it, by using something like new Handler() .
