Queue.Synchronized() Method in C#

This method is used to return a new Queue that wraps the original queue and is thread-safe. The wrapper returned by this method locks the queue before an operation is performed so that it is performed in a thread-safe manner. Syntax:

public static System.Collections.Queue Synchronized (System.Collections.Queue queue);

Return Value: A Queue wrapper that is synchronized (thread safe). Exception: This method will give ArgumentNullException if the queue is null. Below programs illustrate the use of above-discussed method: Example 1: Output:

myQueue is Not Synchronized.
sq is Synchronized.

Example 2:

Runtime Error:

Unhandled Exception: System.ArgumentNullException: Value cannot be null. Parameter name: queue
