I'm wondering why should I use a class that inherits from the EventArgs class instead of using a custom class that will do the same job for me when passing event data?
You don't have to inherit from EventArgs, but it allows people using your classes to use and handle generic *Handler(object sender, EventArgs e) declarations.
If you don't inherit from EventArgs, then they have to use explicitly typed
*Handler(object sender, YairsFakeEventArgs e)
仅使用自定义委托也是如此，但它们明显不同.
The same goes for just using custom delegates but they are a lot more explicitly different.
