Spaces in Enum

[=?Utf-8?B?THVpZ2k=?=]

Hi all,
is it possible to have spaces in enum values?
I have an enum like this:

public enum Columns
{ Italy = 1, OtherCountryUE = 2, OtherCountryOCS E = 3, OtherCountr=
4 }

and I'd like to have

public enum Columns
{ Italy = 1, Other Country UE = 2, Other Country OCSE = 3, Other
Countr= 4 }

but this form is not valid.

How can I solve?

Thanks a lot.

No. The names have to be valid C# identifiers. You may wish to provide
an attribute for each value, if you want a human-readable form.

You can't. The enum-values have to be identifiers, so you are bound by
the naming rules for identifiers. And that means: no spaces.

Why do you want it?

I assume it's for display purposes (populate drop-down or similar).

I have done it quick-and-dirty like that:

//This is my enum
public enum Status
{
Not_selected = 0,
Pending = 1,
Complete = 2,
Re__Notificatio n_Required //NOTE: __ is later replaced with - for
display purposes; _ is replaced with a space
}
//this is a helper that returns a dictionary ~~~: Make itgeneric
public static Dictionary<int, stringGetCaseFl owStatusSelecti on()
{
Dictionary<int, stringret = new Dictionary<int, string>();
foreach (Status status in Enum.GetValues( typeof(Status)) )
ret.Add((int)st atus, status.ToString ().Replace("__" ,
"-").Replace( "_", " "));
return ret;
}
//consum the solution :-)
this.cmbCurrent Status.DataSour ce = new
BindingSource(M yClass.GetCaseF lowStatusSelect ion(), null);
this.cmbCurrent Status.DisplayM ember = "Value";
this.cmbCurrent Status.ValueMem ber = "Key";


Jon, if easy, could you post an example of the attribute solution.

Thanks Jon and Hans.
The reason is that I have to put these Enum as caption of XtraTreeList of
DevExpress Suite.

Does XtraTreeList allow you any way of converting from a value to the
displayed item? (I'd hope so, for internationalis ation purposes if
nothing else.)

Re: Spaces in Enum

Take a look at the "TypeConver ter" class.

Or check out some fancy implementation such as

Hi,

Well, It's pretty obvious why not. What you can do is using a _ but
IIRC MS guidelines do not recommend this. It does prefer OtherContryUE
format

Hi,

You can have a method that transform the enum for you. Not only that
but you could want it in different languages for example.

I think you can achieve with the displayName / tag / value
combinations. The values being enumerated, display name for DevExpress
Tree item can be set to a different value. And Tag is always there to
help. However you need to set tag value to display value.

A little tricky solution...

I'm not so sure for the header text. In some cases you have a
InitializeLayou t method that you can use for it. Dont' know for this
control though.
It can relay in a resource table for globalization
