Decreasing Value In C# Or .NET Enum?
Apr 23, 2012
More for interest than actual need.is it possible to have an automatically decreasing enum in C# or VB.NET?
public enum testEnum
{
this = -1,
that,
other,
}
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.

I have a URL lets say . some time i need to send HTTP and some time i need to send it to HTTPS for that i created a enum:
Private _protocol As Protocol
Enum Protocol
HTTP
HTTPS
[CODE]...
Now when i get value back from protocoltype it returns me integer value as enum do so tell me how to get string from enum or other substitute.
Dim targetUri As String = setting.protocolType & "://www.mysite.com"

I'm trying to declare an enumeration and one of the names I'd like to use for an item is not usable apparently. Where I am declaring 'STEP = 3', I get this error message in visual studio: "Statement cannot appear within an Enum body. End of statement expected." Is it possible to use STEP as an item name somehow? [Code]

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.

I'm using vb but still learning it. Here is the question, I have following ENUM created so that i can use it all the form. I created this Enum on my main form (startup form) and want to use in another form.
Enum MyStatus
Good = 1
Bad = 2
Normal = 3
End Enum
Now from other form I'm using it like frmMainmenu.MyStatus.red. I was wondering how i can make it public or create it in a way so that i don't need to give the prefix frmmainmenu before using its value.

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?

I have a DataType (text, numeric, date, boolean, money) enum and I need to put that in a file. How should I call the file and where in my DataAccessLayer.Generic namespace should I put the file into? Right now the file is called enum.vb and is in theDataAccessLayer.Generic.DataTypes namespace. The Result is ataAccessLayer.Generic.DataTypes.DataType, but it is misleading because the file is called enum.vb

In vb.net, I got an Enum defined As Integer:
Enum enUtilityTypeDetailStudentEntryWorkflow As Integer
enUTDSEW_Default = 379
[code].....
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?

i have a list as an enum and when I want to select values as following, what is the best way to approach it
Public Enum ScanLocations
station1 = 1
station2 = 2
station3 = 3
station4 = 4
end enum
So if i have "station2" as a value in a textbox etc, and I click a button 'next' then it will give me "station3"if i click 'previous' then it will give me "station1"

I have an enum in one module that's used in another that has a long name:
Public Enum Enumwithaverylongname
foo
bar
end Enum
When I use it, I'd like to alias it to a shorter name like:
f.foo
instead of
Enumwithaverylongname.foo
Can I do that?

I know this is a proper enum:
Private Enum Months
JANUARY = 1
FEBRUARY = 2
...
End Enum
However, I want to have an enum where the string will solely be integers.
Example:
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.

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?

Is there any way to put spaces in a C# enum constant? I've read that you can do it in VB by doing this:
Public Enum EnumWithSpaces
ConstantWithoutSpaces
[Constant With Spaces]
[Code]....
That implies to me that the CLR can handle an enum with spaces.
