Queue.Count Property in C# (original) (raw)

Last Updated : 04 Feb, 2019

This property is used to get the number of elements contained in the Queue. Retrieving the value of this property is an O(1) operation and it comes under the System.Collections namespace.Syntax:

public virtual int Count { get; }

Property Value: This property returns the number of elements contained in the Queue. Below programs illustrate the use of the above-discussed property:Example 1:

csharp `

// C# code to illustrate the // Queue.Count Property using System; using System.Collections;

class GFG {

// Driver code
public static void Main()
{

    // Creating a Queue
    Queue myQueue = new Queue();

    // Displaying the count of elements
    // contained in the Queue
    Console.Write("Total number of elements"+
                     " in the Queue are : ");

    // The function should return 0
    // as the Queue is empty and it
    // doesn't contain any element
    Console.WriteLine(myQueue.Count);
}

}

Output:

Total number of elements in the Queue are : 0

Example 2:

csharp `

// C# code to illustrate the // Queue.Count 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");

    // Displaying the count of elements
    // contained in the Queue
    Console.Write("Total number of elements "+
                       "in the Queue are : ");

    Console.WriteLine(myQueue.Count);
}

}

Output:

Total number of elements in the Queue are : 6
