Is queue entry and exit thread-safe?

Queues themselves are not thread-safe. There are two ways to ensure thread safety:

1. Manual locking.

Queue my collection = new Queue()；

Lock (myCollection. Synchronization root)

{

Foreach (object item in my collection)

{

//Insert your code here.

}

}

2. Call the Synchronized method, and you will get a thread-safe queue.

Queue mySyncdQ = Queue。 Synchronization (myq);
