Remove All Objects from the Queue in C#

To remove all objects from the Queue, the code is as follows −

Example

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(){
      Queue<string> queue = new Queue<string>();
      queue.Enqueue("Gary");
      queue.Enqueue("Jack");
      queue.Enqueue("Ryan");
      queue.Enqueue("Kevin");
      queue.Enqueue("Mark");
      queue.Enqueue("Jack");
      queue.Enqueue("Ryan");
      queue.Enqueue("Kevin");
      Console.Write("Count of elements = ");
      Console.WriteLine(queue.Count);
      queue.Clear();
      Console.Write("Count of elements (updated) = ");
      Console.WriteLine(queue.Count);
   }
}

Output

This will produce the following output −

Count of elements = 8 
Count of elements (updated) = 0

Example

Let us see another example −

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(){
      Queue<string> queue = new Queue<string>();
      queue.Enqueue("A");
      queue.Enqueue("B");
      queue.Enqueue("C");
      queue.Enqueue("D");
      queue.Enqueue("E");
      Console.WriteLine("Count of elements = "+queue.Count);
      queue.Clear();
      Console.Write("Count of elements (updated) = "+queue.Count);
   }
}

Output

This will produce the following output −

Count of elements = 5 Count of elements (updated) = 0
