Hi all,
In the following example, I'd like to replace int by a generic. In
order word, I would like to replace int by float, double, byte or
something like that. I've tried to find a common interface or
something like that, but I didn't find.
public static int MaxSum(int[] source)
{
int maxSoFar = 0, maxEndingHere = 0;
for (int i = 0; i < source.Length; i++)
{
maxEndingHere = Math.Max(maxEnd ingHere + source[i],
0);
maxSoFar = Math.Max(maxSoF ar, maxEndingHere);
}
return maxSoFar;
}
In would like to replace this method signature by public static T
MaxSum<T>(T[] source) where T : I???. Thank you for your help.

There isn't one, I'm afraid. This is the kind of thing that generics
just don't work for in their current form :(

Nor in the forthcoming version, AFAIK...
Would you know if this sort of functionality is even being considered for
the future...?

Hi John and Mark,
Thank you for you answer. So, if I understand well, I have to cut and
paste this method with different signature?
- public static int MaxSum(int[] source)
- public static float MaxSum(float[] source)
- public static double MaxSum(double[] source)
- etc.

I wouldn't, I'm afraid. I dare say I wouldn't be allowed to give any
details if I *did* know what's being planned for C# 4, but I'm probably
allowed to say that I don't have the faintest idea what's coming up on
that front.

Yes, I'm afraid so.
If you weren't summing them, you could probably use a constraint of
IComparable<Tan d use CompareTo instead of Math.Max, but I don't know
of any "adding" interface.

I've had the pleasure of meeting Anders a few times. The man could take
on all of the MVPs single handedly in debates over language design and
general programming issues. He's just that knowledgable on the subject, to
the point where it isn't even worth trying to debate him on an issue that he
knows about.

.... if that were true, he would have put in Multiple Inheritence by now.
Obviously, it's not in there because he doesn't understand how it works and
how beneficial it can be (... and if ya believe that one, I've got some
swampland for sale).

I think of generics like I do about operator overloading.
Great to have as a language-feature, as it defines the language more
completely. Great to use.

Hello NewsGroup,
Reading up on Generics in the .NET Framework 2.0 using C# 2005 (SP1), I have
a question on the application of Generics. Knowingly, Generic classes are
contained in the System.Collections.Generic namespace. Literature I have
read on this ties generics in with collections, hence articulate their
examples as such. That's fine, I understand what is being said.
My question is more towards the application and implementation...
