Possible bug in array-related syntax

The last line of code:

var i1 as Integer = Array("A", "B", "C").IndexOf("B")

var s as String = "B"
var i2 as Integer = Array("A", "B", "C").IndexOf(s)

Does not compile on Win Xojo 2020R2.

The first line does compile and produces the correct result.

Is this a bug or intentional?


I meant 2022R2

This DOES work:

var s As String = “B”
var a() As String = Array(“A”,“B”,“C”)
var i1 As Integer = a.IndexOf(“B”)
var i2 As Integer = a.IndexOf(s)

What you are describing seems like a bug or inconsistency to me but in practice the above code is more likely to be what you’d actually use. Otherwise you’re creating an array just to throw it away.

Yeh, but something like

dim s as string = "("
dim isPartOfANumber as boolean = array("0", "1", "2", "3", "4", "5", "6", _
    "7", "8", "9", "+", "-", ".", ",").IndexOf(s) >= 0

would be most useful in a lot of places.

True enough but on a hot path I would define that array once in advance of the loop or outside a very frequently called method. And I have a tendency to do that if it’s going to be called more than once since it’s easy to do.

All that said … I can see no reason that the OP’s code shouldn’t work fine.

It could also be argued that array would serve better being a static but then statics are a whole other world of why is my code misbehaving…
