I have a function that takes a value is as System.Enum and I want to be able
to look at that value and determine if it is a regular enum or an enum that
has a <Flag()> attribute set on it.
I am trying to write a wrapper function that takes an enum and an integer
value and validates if the value is actually part of the enum. Just trying
to use .IsDefined will not return accurate results (as far as I can find) if
the enum is a flag so if it is I want to jump to some other code and try to
validate another way.
I have been looking all over and can't find a way (probably using
reflection) to inspect this and look for any applied attributes.

Hi Raymond,
See it this helps:
<Flags()> _
Public Enum MyEnumWithFlags
A = 1
B = 2
End Enum
Public Enum MyEnumWithoutFl ags
A = 1
B = 2
End Enum
Private Sub Form1_Load(ByVa l sender As System.Object, ByVal e As
System.EventArg s) Handles MyBase.Load
Call f(MyEnumWithFla gs.A)
Call f(MyEnumWithout Flags.A)
End Sub
Sub f(ByVal e As System.Enum)
Dim objType As Type
objType = e.GetType
If objType.GetCust omAttributes(Ge tType(FlagsAttr ibute),
True).GetLength (0) > 0 Then
MsgBox("It has Flags attribute")
Else
MsgBox("It does not have Flags attribute")
End If
End Sub

That is VERY close to what I ended up coming up with :) Spent some more time
working on it last night after I posted and ended up getting it.
Thanks for the post.
I am always in awe of the way people help others here.

I have a custom enum to list comparison operators: =, <, <=, >, >= . I have
created it as follows:
public enum Comparator {Equal, LessThan,
LessThanOrEqual,GreaterThan,GreaterThanOrEqual}
Now I have to create static functions to convert these enum values to/from
the actual comparison operator strings. As I understand it, I can't add
methods to an enum, so is there any more elegant way to do this?

The ToString() function, when applied to a variable that is an enumeration
type, results in a string that is the name of the enumerated value that was
defined in the source code. This is cool, but how does one override the
function to have some values return a different string?
For example, suppose I have an enum with value for the types of DVD media
like
public enum DVD_Media

The help file says that "bit fields can be combined using a bitwise OR operation, whereas
enumerated constants cannot", and yet this code works:
enum Blah { a, b, c }; // without
....
Blah x = Blah.a | Blah.b;
So what is the purpose of the Flags attribute? I understand it's
potentially useful for reflection, so that (for example) the IDE's
IntelliSense knows which enums are meant to be combined, but does it

When working with enums, I've noticed some behaviour that seems
completely counter-intuitive to me. I was wondering if someone here
could help restore my sanity, or at least help me to understand the
"why" of the behaviour.
After dimensioning an enum of type integer, any attribute referenced
seems to, by default, return the name of that attribute as a string,
instead of the integer value assigned to it.

So I was needing some extra power from my enums and implemented the
typesafe enum pattern.
And it got me to thinking... why should I EVER use standard enums?
There's now a nice little code snippet that I wrote today that gives me
an instant implementation of the pattern. I could easily just always
use such an implementation instead of a standard enum, so I wanted to
know what you experts all thought.
Is there a case for standard enums?
