Question

foreach loop iterates over Queue starting from the oldest item and ending with newest.
What if I need to start with newest and end with oldest (probably interrupting at some point as in most cases I just need to iterate over several newest items)?

i’m looking for straighforward and efficient solution. without recreating new objects.

You could use Linq’s Reverse() function:

Queue myQueue;

foreach (var item in myQueue.Reverse())
{
    // do things
}
