Question

    While True
Start:
        Continue While
        GoTo(Start)
    End While

NOTE: I know GoTo will never get reach in this example. I am just wondering if there is any computational difference between using GoTo (X) and (Exit / Continue) statements? I tend to like to use GoTo statements even where Continue or Exit would suffice. Is this bad style? I don’t see GoTo in other programmers code very often.

EDIT: As people kindly pointed out the GoTo would not evaluate the condition on a conditional while loop. Which leads me to ask would the following two pieces of code compile down to the exact same CLR code:

Dim x as Integer = 0
While x < 5
    Continue
End While

And

    Dim x As Integer = 0
JumpPoint:
    If x < 5 Then
        GoTo JumpPoint
    End If

Answer 1

There is one little difference: For Continue, the condition of the while loop is reevaluated, GoTo simple continues execution from the Start label without looking at the while condition.

Start:

    GoTo(Start)

Would be the same as

While True
    Continue While
End While

in terms of “what happens”. But as soon as a condition is introduced, the GoTo wouldn’t do the same.

For your updated question: Yes, there is one difference, again. The first statement includes the Continue which does (basically) the same as the GoTo. But what is not included in your example is a case where the Continue or GoTo is not called because of any operation which took place in between. If Continue is skipped, the End While will just loop over to the next While evaluation and run.
