Thanks for sharing this operator. I hadn't heard of it.
I can't really see why your example of bad use is any worse than any other use. What is your threshold for deciding if a name is likely to change?
This depends on the nature of your code and how often it changes. If you're working with code that's being regularly refactored or evolved, using 'nameof' makes more sense to prevent outdated string literals.
As for the example, it's demonstrating an unnecessary use of 'nameof'. The variable 'name' is defined locally and is not likely to change or need refactoring. Using 'nameof' here doesn't provide much benefit and could potentially make code more confusing to read, because it's not immediately clear that 'nameof(name)' will output the string literal 'name'.
The primary purpose of 'nameof' is to maintain clear and maintainable code, especially for class properties, method names, and other symbols that could change. Using it elsewhere may not provide extra value and could potentially make code harder to understand.
I hope this clarifies it. Thank you for your comment!
My favourite usage is in Exception logging.
When refactoring, it's far to easy to rename a method but forget to do the same in an error logging message. All of a sudden, the error message becomes meaningless/cryptic as it says an exception occurred in a method that no longer exists.
But with
nameof, the message will be updated too when using refactoring tools.Completely agree with you. Using 'nameof' in Exception logging is indeed useful and prevents the possible confusion that can occur after refactoring. You've mentioned a crucial point about ensuring the integrity of the error messages. It makes the code maintainability much easier, as the error messages stay meaningful no matter how much refactoring is done.
Thanks for your insightful comment.
