ArrayList to List<myType> and item disposal

[info]

Hi All,
Suppose you need to release unmanaged resources when you remove an
item from a colletction.

We are now using an override of the ArrayList.Remove() method that
dows the job.

We wanted to move to generics but the List<Tcollection does not
feature any virtual method.

How should we proceed?

We need to release unmanaged resources immediately and cannot rely on
the GC delayed cleanup.
Thanks!

Collection<Tprovides the necessary virtual methods - but it will be
up to your code to ensure that nothing else (other than the
collection) is still using it when it gets disposed.

Nice, but in many cases we resize it to 100,000 and use 90,000. In
your sample this is not possible. In addition resizing would clear the
array contents. I hope that something is changed in .NET 3.5. Do you
know if Collection<Tin .NET 3.5 is more capable?

Thanks again,

Alberto

No problem; I'm glad it helped

Where did you learn these tricks?

Trial and error (mainly error...); and by watching / asking questions
on forums like this.
