C# equivalent to VB.NET 'Handles button1.Click, button2.Click'

Question

In VB.NET I can do

private sub button_click(sender, e) handles Button1.Click, Button2.Click etc...
do something...
end sub

Answer 1

If you want to keep it maintainable, I would go with something like this:

//btnArray can also be populated by traversing relevant Controls collection(s)
Button[] btnArray = new Button[] {button1, button2};
foreach(Button btn in btnArray) {
  btn.Click += button_Click;
}

Any refactoring to this code is done via a single point of maintenance. For example:

• You decide to bind to a custom button class with a custom event, i.e. MyClick.
• You decide to change logic of how buttons are collected, add or remove buttons.
• You figure button_Click is a bad name, or need to have conditional event binding.
