Cast the sender parameter to a Button and look at it's Id (or Name if WinForms)

Button button = sendar as Button
if (button != null)
{
  string buttonName = button.Id;
}

If you want the actual numeric index from the array I would name the buttons with the index number (e.g. MyButton1, MyButton2) and parse it in the event handler.  Or, if it's a Windows app, you could use the Tag property.

If you have a method already defined:

public void MyClick(object sender, EventArge args)
{
  // Do something
}


then use

CheckBox checkBox = new CheckBox();
/// set properties
checkBox.Click += new EventHandler(MyCLick);
