How can I make a generic class convertible in type?
If I have a generic class:
class Collection < G > {
public G[] stuff
}
and I have two other classes, one of which can convert to the other (though more complex than this!)
class Foo {
public Foo( int i ) { myInt = i; }
public int myInt;
}
class Bar {
public Bar( float f ) { myFloat = f; }
public float myFloat;
public static implicit operator Foo( Bar bar ) {
return new Foo( Math.Ceil(bar.myFloat) );
}
}
And I have collections of both:
Collection < G > fooCollection = new Collection < Foo > ();
Collection < G > barCollection = new Collection < Bar > ();
I want to be able to do something like this:
Collection < G > fooCollection2 = barCollection.Convert( typeof(Foo) );
How would I go about that?
This isn't a Unity-related question. I suggest asking this on a more general program$$anonymous$$g board, like Stack Overflow.
Oh right. Thanks, I've done that. Still, if anyone's got an answer here it'd be much appreciated.
Could you define an implicit or explicit conversion?

Otherwise, you may just have to define a Convert method as in your example, though you'd probably need to define it as Convert< T >() - I don't remember offhand if you can pass types as arguments.
You can pass types as arguments. Do you mean add a Convert method to the Collection class, or to the Bar class? On StackOverflow someone suggested this:
Collection<Foo> fooCollection = new Collection<Foo> { stuff = barCollection.stuff.Select(bar => (Foo)bar).ToArray() };
But I don't think that's available in .NET 2.0, is it?
Sure, lambda expressions and LINQ can be used in Unity. Used it alot even on Android and iOS ;)
FanTASTic! Do you mean they can be used straight out of the box, no messing around? Someone on StackOverflow said I would need LINQBridge...
