Is there by any chance an equivalent in Kotlin of .NET Enumerable.Select to convert from enumeration<type1> to enumeration<type2>? Thanks!

[bezrukov]

.map { it.totype2() }

[Sylvain Patenaude]

I'm not sure I follow. I would have to apply/provide some kind of transform method (such as fun transform(t1: Type1): Type2) because Type1 and Type2 are custom types.
Digging a little further, it looks like associateTo might do the trick, wouldn't it?

[Sylvain Patenaude]

Well, associateTo seems to imply a Map as return type, so not quite what I'm looking for, but closing in...

map does exactly what you want

[bezrukov]

listOf(1, 2, 3).map { it * 2} // 2,4,6 as result

[Sylvain Patenaude]

Ah, ok I misunderstood you at first. Thanks Denis!

in c# you will write something like:
users.Select(u => u.name)
in kotlin it
users.map { it.name }
or
users.map {u -> u.name} which make it more similar to c#
