Deconstruction in C# allows us to return multiple values from types. Man scientist

Using extension methods, we can deconstruct ANY type into ANY of its parts. Zombie

Ha that's neat, had no idea that was a thing. A bit more of like scala unapply than an #fsharp active pattern, but I'll take it. Might need to start paying more attention to #csharp.

And it's a C# 7 feature. I saw the tuple pattern matching stuff back then, but never occurred to me to look at user defined deconstruction.

What happens if the type already declares a deconstruct method?

You can have multiple deconstructs, but the same rules apply as they do with Extension methods. So the type one wins out as long as the deconstruction out parameters match.

I wonder why they made it an out-based signature instead of just returning a tuple Thinking face

I like deconstructors - It makes it so much more pleasant when wrapping domain logic (e.g. ways a product number could be structured, or similar things) that you can output them 'nicely' again.

Sadly deconstruction works only for 2+ items, even though you can create tuple with single item Confused face

Thanks Khalid. Like to use it with triples. But I didn’t know, #TIL that we can write our own deconstructer.
