Decreasing Value In C# Or .NET Enum?

Apr 23, 2012

More for interest than actual it possible to have an automatically decreasing enum in C# or VB.NET?

public enum testEnum
this = -1,

So that that = -2 and other = -3.I'm pretty sure the only way to do it is to specifically assign "that" and "other", but I wondered if there was an automatic way of doing it.

Edit To be clear, I'm simply talking about the automatic assignment of the value, not the actual value of the enum decreasing.

Nullable Enum Verse Enum.None?

May 26, 2010

Which is better, using a nullable enum or adding the value None=0 to your enum list?Using nullables requires more code, but I kind of like it since it forces me to think about the possibility.  Otherwise I'm liable to forget about the None enum and fail to account for it being a special case.

Get Enum Given Its Name (convert From C#)?

Oct 14, 2009

How do I do this C# statement in VB.Net (2005):MainMap.MapType =(MapType)comboBoxMapType.SelectedValue;MainMap only accepts Types so passing the Integer value of the type is not possible. The combo contains a list of strings:comboBoxMapType.DataSource = Enum.GetValues(typeof(MapType));In my case I need to limit the list to less than 100% of the Enum values so code similar to .Datasource= code will not work.So in general I need a way to return an enum given the name of the enum.Maybe I should just do a Collection of Enums (if that is even possible) and use the name as the Key?

Why Does Enum Need To Use A CType

In, I got an Enum defined As Integer:

This works but it adds a lot of noise to the code and it seems like the Enum is already defined as an Integer, making me think, why do I have to assign it again?

An Integer String In An Enum?

Oct 8, 2010

I know this is a proper enum:

Private Enum Months
End Enum

However, I want to have an enum where the string will solely be integers.


Private Enum ColumnCounts
01 = 5
02 = 4
03 = 40[code].....

Essentially, I didn't want to put the f in there, just wanted to do 01. The way this will be called is:

Select Case (nRecordType)
Case "01"
Case "02"[code].....

Because I'm not making an instance of it and not calling a constructor, there's no way to autopopulate a Dictionary.And I don't want to convert to integer so I'm not going to do an array. That is just in case eventually the value gets above 99 and the next value would be A0.I'm trying to think of easy future changes to this and backwards compatability.If you need more explanations, let me know.

Edit 2:This is what I've done now and I think it should work:

Public Class Part
Private Shared columnCounts As Dictionary(Of String, Integer) = New Dictionary(Of String, Integer)
Public Shared Function ValidateColumns(ByRef lstFiels As List(Of String)) As Boolean[code]....

I can't verify that it's going to do what I want to, but it doesn't give me an error when I build it so I'm crossing my fingers.

Generic Based On Enum

Sep 2, 2009

I have a generic class Class MyTestClass(Of T)where I know that T will only ever be an enum.  Is there any way to declare this restriction to the compiler?And a second question: If the answer to my first question is 'no, there isn't', then what's the best way to cast T to a plain integer? Doing that is difficult when the compiler doesn't know that T is always an enum. [code]That certainly works, but it looks nasty as it apparently involves unnecessarily boxing and then unboxing the enum value. Is there a better way of doing it?
