Using string constant for notify property changed

Question

I am working with some existing code and trying to figure out the advantage (if any) of using a string constant for the name of a property when implementing INotifyPropertyC

Answer 1

There isn't an advantage compiler wise, since both will end up being a constant value.

I can't imagine a real advantage in using the code like that way. Either ways it is easy to make a typo, and you are not going to reuse that constant for anything, so it is pointless.

I had love to see the new nameof keyword implement in the next version of .NET. Or even better, if possible, use [CallerMemberName] as Marc Gravell suggested.

The use of nameof will be useful when having custom calculated properties (like in WPF for example) that don't have their own getter / setter.
