I was implementing a method to launch the event PropertyChanged
of INotifyPropertyChanged
. I did the validation of the event in a traditional way, ie with if (PropertyChanged != null)
. But the VS suggested me a leaner form that is PropertyChanged?.Invoke ( this, new PropertyChangedEventArgs ( propertyName ) );
.
It’s obvious that the code is self-explanatory, meaning, "If PropertyChanged
is not null, execute the method Invoke
". But I wanted to know what this resource is called so I can research more information about it.
