Android Question Does SELECT CASE needs the EXIT statement?

[wonder]

Which one is correct?

'Example A:
Dim n = 0 As Int
Select n
    Case 0
        n = 1
        Exit
      
    Case 1
        n = 100
        Exit

End Select

or

'Example B:
Dim n = 0 As Int
Select n
    Case 0
        n = 1      
      
    Case 1
        n = 100      

End Select

Thank you!

it already implements a break. some languages (PHP for example) require that you set it yourself tho.

I'm almost sure that you can even add a break (which is not needed) using Continue (it works on loops).

Damn, now I have to try

Tried: it's False , Continue cannot be used.

Exit case is not a Basic statement. In C and related dialects you need to Exit since every subsequent statement will be executed also if it"s not the case...
In Basic every single case is tested.

With VB.Net you can exit from a single case, using Exit Select:

Dim a As Integer = 3
Dim b As Integer = 30

Select Case a
    Case 3
        Debug.WriteLine("Executed before exit")
        If b = 30 Then
            Exit Select
        End If
        Debug.WriteLine("Executed after exit") ' <--- this line will not be executed
End Select
