Enumeration

[shapper]

Hello,

I have an Enum:

Public Enum City
NewYork
London
End Enum

How do I get the index of a certain item?

Thanks,
Miguel

All enum values should equal an integer value, so you can just cast it
as an integer.

Hello,

After much reading and much googling I came up with this:

Get names and indexes of enum:

For Each color As Color In [Enum].GetValues(GetType(Color))

Dim name As String = MyF(color, Thread.CurrentThread.CurrentCulture)
Dim index As Integer = CType(color, Integer)

Response.Write("Name: " & name & " | Index: " & index.ToString & "<br
/>")

Next

MyF is a function which returns a string for a giving culture and enum
name:

Public Function MyF(ByVal color As Color, ByVal culture As CultureInfo)
As String
....

Get one enum name from its index:

Dim s As String = "20"
Dim i As Integer = CType(s, Integer)

If Color.IsDefined(GetType(Color), i) Then

Dim name As Color = CType(i, Color)
Response.Write(name.ToString)

End If

Need second opinion. What do you think?

I am asking this because my Response.Write seems to show the right
results but further on in my code I am having some problems and I am
not sure if it comes from here and until now I wasn't able to figure
this out.

Thanks,

Miguel
