I came across an easy way to get rid of some boiler plate code I am always writing when writing event handlers. Consider this example:
public event EventHandler SomethingHappened;
private void OnSomethingHappened() {
var handler = SomethingHappened;
if (handler != null) {
handler(this, EventArgs.Empty);
}
}
In the OnSomethingHappened() method there's a lot of unnecessary boiler plate code to make sure that we don't run into a NullReferenceException.
With a small change to the setup we can do the same with much less coding. Consider another improved example:
public event EventHandler SomethingElseHappaned = delegate { };
private void OnSomethingElseHappened() {
SomethingElseHappened(this, EventArgs.Empty);
}
That was easy! I'm gonna do this from now on!
Happy coding!
