A PriorityQueue is a list that always keeps its items sorted based on some rule, like smallest to largest. So, when you take an item out, you always get the one with the highest (or lowest) priority.

The ConcurrentStack and ConcurrentQueue classes, lock-free and thread-safe implementations of the Stack and Queue classes, build thread safe collections in .Net ...

Among other things, the paper demonstrates that the Adapter pattern is useful for designing stacks and queues. The demonstration code is shown in Listing 1. Listing 1.

You can create lists that function as stacks (first in, last out lists) or queues (first in, first out lists). Using a List as a Stack To use a list as a stack, use the INSERTC, INSERTN, INSERTL, or ...
