In Perl (and other languages) a conditional ternary operator can be expressed like this:
my $foo = $bar == $buz ? $cat : $dog;
Is there a similar operator in VB.NET?
This question is related to

iif has always been available in VB, even in VB6.
Dim foo as String = iif(bar = buz, cat, dog)
It is not a true operator, as such, but a function in the Microsoft.VisualBasic namespace.
If() is the closest equivalent but beware of implicit conversions going on if you have set "Option Strict off"
For example, if your not careful you may be tempted to try something like:
Dim foo As Integer? = If(someTrueExpression, Nothing, 2)
Will give "foo" a value of 0!
I think the '?' operator equivalent in C# would instead fail compilation
Just for the record, here is the difference between If and IIf:
IIf(condition, true-part, false-part):
If(condition, true-part, false-part):
