How to understand the thread safety of Queue in C #, many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can get something.

Enumerating through collections is not a thread-safe process in nature. Even when the collection is synchronized, other threads can still modify the collection, which causes the enumerator to throw an exception. To ensure thread safety during enumeration, you can lock the collection throughout the enumeration or catch exceptions that are thrown due to changes made by other threads.

The following examples show how to synchronize the Queue, how to determine whether the Queue is synchronized, and how to use the synchronized Queue. Unity3D tutorial manual

Using System; using System.Collections Public class SamplesQueue {public static void Main () {/ / Creates and initializes a new Queue. Queue myQ = new Queue (); myQ.Enqueue ("The"); myQ.Enqueue ("quick") MyQ.Enqueue ("brown"); myQ.Enqueue ("fox"); / / Creates a synchronized wrapper around the Queue. Queue mySyncdQ = Queue.Synchronized (myQ); / / Displays the sychronization status of both Queues. Console.WriteLine ("myQ is {0}.", myQ.IsSynchronized? "synchronized": "not synchronized"); Console.WriteLine ("mySyncdQ is {0}.", mySyncdQ.IsSynchronized? "synchronized": "not synchronized");}}

By comparing the running results, it is clear that the Queue wrapped by the Queue.Synchronized method is synchronized, while the unwrapped one is not synchronized. You can declare this at the instantiation

/ / Creates a synchronized wrapper around the Queue. Queue mySyncdQ = Queue.Synchronized (new Queue ()); is it helpful for you to read the above content?
