Avoiding primitive obsession in .NET

[Richard Deeming]

Wrapping every primitive value in a class like that is going to dramatically increase the memory usage of the application, and potentially decrease the performance. After all, there's a reason Java has stack-allocated duplicates of certain heap-allocated classes. The author should really be using a struct for the wrappers - and preferably a record struct.

You can report anything you want; anything you feel violates CodeProject's ethos. There is a big difference between my comments on the history and linguistics of the Vedas and Sanskrit, on the Mahabharata as drama and metaphysical allegory, and a direct quote from a scripture used as a talking point. I very carefully avoided anything that showed disrespect for Hinduism the same way as I would carefully avoid showing disrespect for Christianity, Islam, etc. The quote (in Urdu) I used from Kabir is poetry. Glad to hear you read my posts !

What, no "stringly" typed data?

Bill, It's probably just poetry. My way of expressing myself in Walcott-esque style. [THE LIGHT OF THE WORLD - Derek Walcott - Saint Lucia - Poetry International](https://www.poetryinternational.com/en/poets-poems/poems/poem/103-28371\_THE-LIGHT-OF-THE-WORLD) Read it to see if you can find that deeper meaning. Might have to read it three or four times. :thumbsup:

Yeah, it's called semantic types, and I wrote about this[^] in 2018. :rolleyes:

I thought the author’s “fixed” code was awful. Why leave email as a string? Boolean is the worst primitive for this, why did the author leave a boolean? I am trying to get a law passed that all booleans should be converted enums. If I see a class named ClubMember, I would never expect to call ClubMember.isMember(), ever. Maybe ClubMember.getMembershipStatus(). Oof!

In a similar vein, the ClubMember type in particular made me wish (again) that C# supported enum types with methods.

Extension methods will get you close to that:

public enum ClubMember
{
NonMember,
Member,
}

public static class ClubMemberExtensions
{
public static decimal CalculateAmount(this ClubMember member, decimal productValue) => member switch
{
ClubMember.Member => productValue - 10,
_ => productValue,
};
}

That's easy:

public enum Bool
{
True,
False,
FileNotFound,
}

Too funny. I used to visit that site, but their security was so bad that I thought I would pick up a virus from the comments. That very meme flashed through my mind while I was posting.
