Global Objects

Really what I want is an enumeration that returns strings rather than
integers. Since, as far as I know, that's not possible, I thought to create
a class with shared members that return strings. Kind of like a qualified
constant list so that you can type the name of the class and then get, via
intellisense, a list of the possible values.

I thought that if I created a class with nothing but shared variables, I
wouldn't have toi instantiate it before I used it, since the members were
all shared. Kind of like using the Math object. You just use it, don't
declare one first.

However, it's not working. The compiler keeps complaining that I don't have
an instance. How do I create a class that acts like a global instance?
Thanks.

If you are using VS 2005, check out the first source code listing at

Hi Jerry,

Thanks for posting!

Herfried's suggestion is appreciated! Since the enumeration type only
allows the storage of numeric type, there are some other ways to approach
the current demand.

In addition, we can use the custom attributes to be a workaround. The
following article from the CodeProject demonstrates how to use the
StringValueAttribute for the enumeration type in C#:
http://www.codeproject.com/csharp/stringenum.asp

I hope this will be helpful. If you need a VB.NET version, please feel free
to let me know. It's my pleasure to be a future assistance.
