Argument Modifiers: 'ref', 'out', 'params' and 'this'
Some c-sharp devs must slink through their whole skanky career, utterly ignorant about argument modifiers.
There's usually a way to avoid thinking about them: if you're willing to write a lot more code and have your existing stuff crash and get patched many more times.
The best known 'argument modifier' is probably '
ref' -- and it's purpose is pretty damn powerful. I assume you know its purpose: but just imagine you've just gone from a state of not knowing what the
ref param modifier does, to a state where you know what it does. Think of all the things you couldn't do before that are now open to you. Hold that thought.
I'd say that I use '
out' possibly a little more often than I use '
ref' -- yet I wouldn't rank it quite so high on the 'mind-blowing' stakes. The '
params' argument modifier is certainly mind-blowing, if you've never used it before. It gives the language a whole big chunk of 'affordance' -- allow you to achieve, very simply, ranges of motion that are otherwise almost inachievable.
But what about the '
I'd wager that 70% of the C sharp devs out there haven't yet parsed the '
this' argument modifier.
And when they do -- i hope to see the nightsky light up with the colourful spectacle of a hundred thousand minds noisily exploding under the power of extension methods.
If you're part of that sad 70%, go now and learn how to implement an extension method or ten.Next → ← Previous
