Hi folks,
There are some cases when you need to pass an empty EventArgs to an event handler. I’ve been seeing the following code (which makes me really sick) lately over and over again:
MyEventHandler(this, new EventArgs());
Take a look at MSDN and you’ll see there’s a static read only field named Empty in the EventArgs class to be used in such scenarios. Therefore, the correct way to make the above call follows:
MyEventHandler(this, EventArgs.Empty);
The framework also contains more classes with the Empty field, say, String, Type, Color, Point and Size to name a few:
- String.Empty means the literal ” “.
- Color.Empty means “new Color()”.
- Point.Empty means “new Point()”.
- Size.Empty means “new Size()”
- Rectangle.Empty means “new Rectangle()”
- Type.EmptyTypes means “new Type[] { }”.
Happy coding!
