Custom object for undefined values

Hi!

 

i'm not really sure if this is the topic for this forum but...let's give it a
try ;)

 

I want to make a public class for undefined values. So, what do I mean by that
huh? For example, when I set values for some object in constructor, I would like
to assign undefined value let's say for integer. Something like: Undefined.Int
(where the value would be I don't know, -274356238?). Something like bulit in
string.Empty thing...

 

Can someone sets me in the right direction, I need some clues. I don't want
enumerator. I want to access this class from wherever (Page, CodeBehind,
business logic layer, DAL...)

 

Thanks!

How about using nullable values? 

int? i = null;

if (i.HasValue)
{
  // i has non-default value
}
else
{
  // i has no value; i == null evals to true
}

You could use Nullables. I often use MinValue, but if you wanted your own values
(for value types), something like: public static class DefaultValues {   public
static readonly int Int = -274356238;   public static readonly string String =
"NULL"'; // not actually a value type, but since it's immutable, we
can treat it as one   public static readonly DateTime DateTime = new DateTime(1,
1, 1900);} should do the trick.
