What is the use of. NET Foundation EventArgs

Suddenly found that EventArgs is nothing to use, it is similar to ViewModel, just that this class is stored data, do not inherit EventArgs program can also run.

With this there is only one benefit, that is, no matter what eventargs we define, the method can be replaced with this parent class. Such as

public void Btn_click (EventArgs args)

{

}

Similarly, if we are to derive a ViewModel base class for ViewModel in MVC, then all methods that call this ViewModel can also be written as

public void Showmodel (Viewmodel model)

{

}

However, there is no egg to use, and it is necessary to make the parent class as our actual subclass before using the methods in this subclass. It's a chicken-like thing, and the only use of this is to unify the event parameters in the Webform,winform into EventArgs args.
