lists, get last item, 2 second question

[Nick Valeontis]

Is there a way to get the last item added to a generic list? That is,
without using the count property.


Something to improve this code:


schedule.jobs[schedule.jobs.Count-1].tasks.Add( ... );



With regards,

Nick

What's wrong with using that code?

 

[Nick Valeontis]

Nothing wrong.

I can't remember where (book or site etc) but I would swear I have seen a
better way to get the last index of a generic list.

Like a property, eg : schedule.jobs.getlastitem.tasks.add( ...);

But I can't find it now, so I guess it was in my imagination, or perhaps a
different language ;-)

Nick,

I suppose you could do the following.

schedule.jobs.FindLast(delegate(Job x) { return true; });

That's assuming that FindLast actually starts it search from the last
item. It's pretty ugly if you ask me.

A lambda expression would be pretty elegant; perhaps more so than the
..Count - 1 technique.

schedule.jobs.FindLast(x => true);

You'll have to wait until C# 3.0 for that though.

K, thanks Brian!

I will have that in mind.

You may be thinking of a linked list that has Last and RemoveLast methods.
Depending on what your doing a LL may be a better choice anyway.
