Try this 

Dim m As MenuItem = TryCast(sender, MenuItem)
audioDevice = (IIf(m.Index>0, filters.AudioInputDevices(m.Index-1), Nothing))

IIf Function MSDN Documentation

As IIf Function is deprecated use like this

If m.Index>0 Then
    audioDevice = filters.AudioInputDevices(m.Index-1)
  Else
    audioDevice = Nothing
  End If

Sample

Hope it helps

Here is probably the best tool I have ever found! And having been a developer for over 10 years, when I found this (And with most examples online being in C, this was just GOLDEN!) .. Hope this helps you! (And anyone else that hasn't stumbled across this 'gem'... Finally VB coders have better access to online examples... NOTE* this isn't the only code converter, but it's by far the best one I have ever used.. Perhaps if you convert the code again using this, your troubles might be solved.......

Are you running VB.Net 2008 or later? The If operator is not supported in earlier versions.

Since the non-short-circuit Iif function will cause the true-part of the expression to cause an index out of range, you should use an If Then Else statement if you want a version prior to 2008 to be supported.
