Use this code (it's a console app):

Module Module1

Public Enum MyColors
RED = 0
GREEN = 1
BLUD = 2
ORANGE = 4
End Enum

Sub Main()
Dim i As Integer = [Enum].GetValues(GetType
(MyColors)).Length
Console.WriteLine("Number of values = {0}",
i.ToString)

For j As Integer = 0 To i - 1
Console.WriteLine("{0} - {1}", [Enum].GetNames
(GetType(MyColors)).GetValue(j), _
Convert.ToInt32([Enum].GetValues(GetType
(MyColors)).GetValue(j)))
Next

Console.ReadLine()
End Sub

End Module
