Which data structure is better in a particular case?

Question

Data Structures

Which is more performant in CIL for FIFO implementation: Queue or a class that has a List listName and contains an Enqueue method whose implementation looks like this: listName.Insert( 0, listItem);

Answer 1

Well, Queue will be more reliable - a thoughtful, tested and time-tested class.
There must be a good reason to write your turn

Answer 2

Firstly, take it and conduct a test, if performance is so critical to you, guessing in such situations is useless.
Secondly, I am more than sure that Queue will be enough for your eyes and ears, and you are simply distracted by unimportant things.
