Queue.IsSynchronized Property in C# Last Updated : 04 Feb, 2019 Comments Improve Suggest changes Like Article Like Report This property is used get a value which indicates whether access to the Queue is synchronized (thread safe) or not. Syntax: public virtual bool IsSynchronized { get; } Property Value: This property returns true if access to the Queue is synchronized(thread safe) otherwise, false. The default is false. Below programs illustrate the use of the above-discussed property: Example 1: csharp // C# code to illustrate the // Queue.IsSynchronized Property using System; using System.Collections; class GFG { // Driver code public static void Main() { // Creating a Queue Queue myQueue = new Queue(); // Inserting the elements into the Queue myQueue.Enqueue("C"); myQueue.Enqueue("C++"); myQueue.Enqueue("Java"); myQueue.Enqueue("C#"); myQueue.Enqueue("HTML"); myQueue.Enqueue("CSS"); // Creates a synchronized // wrapper around the Queue Queue sq = Queue.Synchronized(myQueue); // Displays the synchronization // status of both Queue Console.WriteLine("myQueue is {0}.", myQueue.IsSynchronized ? "Synchronized" : "Not Synchronized"); Console.WriteLine("sq is {0}.", sq.IsSynchronized ? "Synchronized" : "Not Synchronized"); } } Output: myQueue is Not Synchronized. sq is Synchronized. Example 2: csharp // C# code to check if Queue // Is Synchronized or not using System; using System.Collections; class GFG { // Driver code public static void Main() { // Creating a Queue Queue myQueue = new Queue(); // Inserting the elements into the Queue myQueue.Enqueue(1); myQueue.Enqueue(2); myQueue.Enqueue(3); myQueue.Enqueue(4); // the default is false for // IsSynchronized property Console.WriteLine(myQueue.IsSynchronized); } } Output: False Note: Retrieving the value of this property is an O(1) operation. To guarantee the thread safety of the Queue, all operations must be done through the wrapper returned by the Synchronized method. Enumerating through a collection is intrinsically not a thread-safe procedure. Even when a collection is synchronized, other threads can still modify the collection, which causes the enumerator to throw an exception.

Queue represents a first-in, first out collection of object. It is used when you need first-in, first-out access of items. 2 min read Queue.Count Property in C# This property is used to get the number of elements contained in the Queue.

This method is an O(n) operation, where n is the total count of elements. And this method comes under System.Collections namespace. Syntax: public void Clear (); Below given are some examples to understand the implementation in a better way: 2 min read Queue.Clone() Method in C# This method is used to create a shallow copy of the Queue. It just creates a copy of the Queue. The copy will have a reference to a clone of the internal elements but not a reference to the original elements. Syntax: public virtual object Clone (); Return Value: The method returns an Object which is 2 min read Queue.Contains() Method in C# This method is used to check whether an element is in the Queue. This method performs a linear search, therefore, this method is an O(n) operation, where n is Count. And this method comes under the System.Collections namespace.

The elements are copied to the Array in the same order in which the enumerator iterates through the Queue and this method is an O(n) operation, where n is Count. This method co 4 min read Queue.Dequeue Method in C# The Dequeue() method is used to returns the object at the beginning of the Queue. This method is similar to the Peek() Method. The only difference between Dequeue and Peek method is that Peek() method will not modify the Queue but Dequeue will modify. This method is an O(1) operation and comes under 2 min read Like
