iif and type inference

[Maurizio Colucci]

Hello,

Is there a way in VB.NET to do something like

dim myInt = if foo() then bar(3) else 4

and have the compiler infer that myInt is an Integer, since bar()
returns an integer and 4 is an integer?

Thanks a lot for any info.

No, there is not a short equivalent of if-else in VB.NET as there is in C#
(condition ? true : false) but if you are sure that both statements return
an object of the same type, you can cast the result of IIf: CInt(IIf(foo(),
bar(3), 4)) in your case.

Hello Maurizio,

Since the code is not sooo difficult - why don't you just give it a try?

Best regards,

I'm sorry, I don't think I understand that you mean.

Thank you, I was afraid that was the only way. It also does not use
lazy evaluation.

Which version ? If VB 2008, you could use the new If function :

Dim myInt = If(foo(), bar(3), 4)
