Question

I notice that both of these compile without any compiler warnings or errors, even with Option Strict and Option Explicit both turned on:

    Dim x As Exception = New Exception("this is a test")
    Dim y = New Exception("this is another test")

My question is, is it more proper to use the first way (see variable x) or the second way (see variable y)? My guess is that VB doesn’t need the As clause since the variable is being initialized in place, so the compiler can infer the type.

I tend to like the first way as it just “feels” right and is more consistent with other languages like C#, just wondered if there was some good reason for one way over the other. I guess it’s really personal choice.

Answer 1

I’d do Dim x As New Exception("this is a test"). Best of both worlds, no infering but you still only have to type Exception once 🙂
