Personally I prefer the IComparer to the IComparable interface (especially in your case where you may have many different ways of comparing the items).

Could you not implement the IComparable interface in the DocumentReference class. This requires you to implement a single method, CompareTo that determines if another object is "bigger than" , "equal to" or "less than" the implementing object. The Sort methods of Array and ArrayList use this method to decide what the order of items in the array are. How you determine the relative position is strictly up to you. You can use one property or a dozen; it is strictly your call. You could even use a random number if that were your fancy.Jon Stonecash > Date: Fri, 15 Sep 2006 14:06:54 -0400> From: [EMAIL PROTECTED]> Subject: [ADVANCED-DOTNET] ArrayList Sort Method> To: [email protected]> > I have an unusual situation or at least I think I do.
