Let's say I have an Enum
Enum Items
Item1 = 0
Item2 = 1
Item3 = 2
Item4 = 4
End
and I have a method which accepts this Enum as parameter:
Sub Test(byval Item as Items)
'Code
End Sub
Is it possbile to provide an integer value, corresponding to the Enumeration
index?
Like: Test(3)
Of course I get an error in IDE,if Option Strict is On, so how to convert
this intger to the corresponding Enum?
TIA 5 1170
One of the reasons for enums is to make code easier to read. If you are
going to pass the value 3 why not just pass the enum that represents that
value? Thats really the purpose of an enum as I understand them.

simply use CType whenever you want conversion in between integer and your
enum.

Actually would it not be better to use DirectCast?
I always get confused between the two (DirectCast and Ctype) and when to use
them.

Yes DirectCast is generally considered faster as it only does CASTING and
not conversion as compared to CType.
Here are couple of links that might explain more http://msdn.microsoft.com/library/de...tinternals.asp http://groups-beta.google.com/group/...b28bc12e70c56d http://groups-beta.google.com/group/...ceb63f71df6bb1

As a side note, I would mention that casting a 5 to your enum will not
generate any exception. If you do not trust the client of your routine (for
such a problem) it could be worth to check the value is valid.
