Description

is somewhere in the queue
Rules at a Glance
obj
must correspond exactly to an item in the queue for the method to returnTrue
.The method searches the queue sequentially. In other words, its performance is inversely proportional to the number of items in the queue.

In comparing objects in the queue with
obj
, the Contains method in turn calls the
BCL’s Object.Equals method to perform the
comparison. The Equals method returns True
if two
object instances are the same instance.
