I have a list of strings each represented by a number. I want those
string to be constant and put as litle hit as I can on the performance
of my application. The strings are mutualy exclusive, juste like an
Enum. I would use the Enum, but my string contains special caracter
and spaces. I would use a dictionary, but then the string could be
changed at runtime and it would add unnecesary overhead to my
application.
What would be the best solution?

Hmmm... Maybe a custom EnumConverter? http://weblogs.asp.net/mnolton/pages...merations.aspx

Interesting to say the least. I think it is a litle too complicated
for my project though. It seems to adds a lot of complexity to the
code.

You could make an enum using underscore instead of space to gain all the
benefits of an enum. As needed, you could do such things as overriding
ToString to replace underscore with space, etc.

You could use constants or 'ReadOnly' string fields instead of the

For the latter would generics do a fine job.

The string are constant. It's the type of supplier in a financial
application. The problem is, in some flat files, the type are written
in string, but in the database, they have been mapped to an integer
field to save space.
ex:
1 Intermédiaire
2 Personne morale
3 Personne physique
...
etc.
As you can see, the type have space in them and some spécial caracter
i'd rather not have or can't in a enum name. What i would realy liked
would have been an enum where I could have used the space and special
caracter

Look pretty good I could probably tinker with it. It's probably not as
efficient as an enum, but I doubt I can have both world.

No, a standard dictionary would do, I need the key as an integer and
the value as a string.
I believe I'll have to fall back to some form of arbitrary enum like
M. Wagner suggested. It's probably more efficient that using a read
only Dictionary

I was to track some additional properties around an enum I have - for

it could be used for all enums.
I also need to be able to store and manage a collection of these

If a class inherits from another class, say Form inherits from control, then
I can assign the Form to a variable of type Control without needing an
explicit conversion, eg
Form1 f = new Form1();
Control c = f;
An enum value inherits from int but it doesn't get implicitly converted:

So I was needing some extra power from my enums and implemented the
typesafe enum pattern.
And it got me to thinking... why should I EVER use standard enums?
There's now a nice little code snippet that I wrote today that gives me
an instant implementation of the pattern. I could easily just always
use such an implementation instead of a standard enum, so I wanted to
know what you experts all thought.
Is there a case for standard enums?
